Since version 8.19 (18.02.2020), a method for retrieving resources with base64url encoded values has been available for all resource endpoints.   This makes it possible to use characters otherwise reserved in URL, i.e: : / ? # [ ] @ & * + ;  To use it, one simply adds b64(encodedValue) in place of the resource name when you make your request.   Below is an example of how this works. Inventory item with several reserved characters: Getting this without encoding the resource name will result in an error: GET /Inventory/:/?#[]@&*+;   If you instead encode the value with base64Url encoding: :/?#[]@&*+;  ⇾ Oi8_I1tdQCYqKzs, and insert it in the b64 method you will get the wanted item: GET /inventory/b64(Oi8_I1tdQCYqKzs)   If you want to read more about base64Url encoding, please have a look at the following links: RFC 4648 § 5  Base64Guru base64encode

About paging When getting lists of data from API-endpoints it will be most efficient for both the client and server to divide the result into portions instead of getting all the data returned at once. The Visma.net API supports this by implementing a method called paging. Paging means that when you request lists of data you should also provide two extra query-parameters called pageSize and pageNumber. pageSize: The maximum number of records you want to have returned on each page (the length of each page) pageNumber: The page you are requesting.   Example In the database you have 350 customers, you make a GET request to the Customer-endpoint to get all these. To limit the number of customers received you can divide this into pages that contain upto 100 customer (pageSize=100). To get the complete list you then have to make 4 requests to the Customer-endpoint:     Request Result 1 GET /customer?pageSize=100&pageNumber=1  Returns the first 100 customers (1-100) 2 GET /customer?pageSize=100&pageNumber=2 Returns the second page of 100 customers (101-200) 3 GET /customer?pageSize=100&pageNumber=3 Returns the third page of 100 customers (201-300) 4 GET /customer?pageSize=100&pageNumber=4 Returns the last page of remaining customers (301-350)   Paging is implemented on all GET endpoints that returns lists in the Visma.net API. It is mandatory to use the parameters pageSize and pageNumber in all requests to endpoints that support this. How paging is implemented in Visma.net API For all endpoints that return lists paging is implemented by providing two queryparameters, pageSize and pageNumber. For all endpoints these parameters are documented in the swagger documentation (https://integration.visma.net/API-index/). For all endpoints that provide these parameters it is important that your integration provide these for all requests. If not provided default-values will be used and you will potentially not receive the complete resultset. In the swagger-documentation you can see the default-value for the specific endpoint. Default parameter values Parameter Default value (if not provided) pageNumber 1 pageSize Can vary from endpoint to endpoint, can also change over time. Maximum value for the pageSize parameter is bound to the default-value that will also represent the maximum value allowed. Meaning that if you specify a value in pageSize that is greater than the default value, the endpoint will only return the number of records defined by the default value for pageSize in this endpoint. In addition to swagger-documentation the maximum allowed value for pageSize will also be returned as part of the metadata-property in the returned JSON-data. The value will have the name maxPageSize.         "metadata": { "totalCount": 450, "maxPageSize": 500 }         Metadata As part of every request to an endpoint that supports paging you will get a metadata-property returned as part of the returned JSON-data. This metadata is provided to give your integration information about the available results and restrictions of the current request. The metadata-property will provide the following values:         "metadata": { "totalCount": 450, "maxPageSize": 500 }           Value Description totalCount The total number of results for the current request regardless of pages. Example: GET /customer?name=Norwegian?pageSize=5&pageNumber=1 This request will return the first page of 5 customers with the name containing “Norwegian”. However, in the database there are 12 customers with names containing “Norwegian”, so the totalCount will have the value 12. maxPageSize The maximum pageSize you can set for this endpoint. If you specify a number higher than this, the result will be restricted to only return the maxPageSize number of records.   You can use the values in the metadata to calculate the number of pages you need to get in order to receive the whole result-set based on the pageSize you are using. Paging in combination with filters Most GET-endpoints in the API contain filter-parameters. These are used to narrow down the resultset to only contain the records that are relevant to the request. It is important to notice that when these filter-parameters are used in combination with the paging-parameters, the resultset is defined as the total resultset for the specified filter-parameters. This means that if the resultset spans across multiple pages, the exact same filter-parameters must be specified for all subsequent requests to get the following pages. The Visma.net API contains no state to store what pages/records have been delivered, so every request will be handled independent of previous requests. The figure below illustrates what results will be included in each page based on three different queries with different values for parameters lastModifiedDateTime and pageSize. Query 1: ?lastModifiedDateTime=2020-03-01T00:00:00&lastModifiedDateTimeCondition=>=&pageSize=3 The resultset will be divided into 4 different pages, meaning that you have to make 4 requests to the API, with the exact same values for parameter   lastModifiedDateTime, lastModifiedDateTimeCondition   and   pageSize. The pageNumber-parameter will define what results you will get, marked by the numbers 1-4 and the colors yellow, pink, green and blue in the figure.   Query 2: ?lastModifiedDateTime =2020-03-01T00:00:00& lastModifiedDateTimeCondition =>=& pageSize =5 The resultset will be divided into 2 different pages, meaning that you have to make 2 requests to the API, with the exact same values for parameter  lastModifiedDateTime, lastModifiedDateTimeCondition  and  pageSize . The pageNumber-parameter will define what results you will get, marked by the numbers 1-2 and the colors green and purple in the figure.   Query 3: ?lastModifiedDateTime=2020-03-06T00:00:00&lastModifiedDateTimeCondition=>=&pageSize=3 The resultset will be divided into 2 different pages, meaning that you have to make 2 requests to the API, with the exact same values for parameter lastModifiedDateTime, lastModifiedDateTimeCondition and pageSize. The pageNumber-parameter will define what results you will get, marked by the numbers 1-2 and the colors blue and gray in the figure.                                                                           If you do not keep these parameters constant (the pageSize is changed), and do the following set of requests:   ?lastModifiedDateTime=2020-03-01T00:00:00&lastModifiedDateTimeCondition=>=&pageSize=3&pageNumber=1 ?lastModifiedDateTime=2020-03-01T00:00:00&lastModifiedDateTimeCondition=>=&pageSize=5&pageNumber=2 This will result in you getting the following records: First request: Record 1,2,3 Second request: Record 6,7,8,9,10 As you can see the records 4 and 5 will not be returned to you. New records added while getting pages Sometimes new records are added to or removed from the database by other uses while you are getting the records using paging. In that scenario the totalCount metadata-property will always change to reflect the new total number of records available for your query. Because of this it is important to always check the value of totalCount for each GET request to retrieve a new page, to be able to calculate the total number of pages needed to get the complete resultset. Example You want to get all the customer with status=”Active”, the results should be divided into pages with 10 customers (pageSize=10). You make the following request to get the first 10 customers. GET/customer?status=Active&pageSize=10&pageNumber=1 As part of the response you get the metadata including the totalCount - property that tells you that the total number of results are 30.     "metadata": { "totalCount": 30 }       3. This means that you have to repeat the request two more times to get the full result-set. 4. You make the second request to get the next 10 customers. GET/customer?status=Active&pageSize=10&pageNumber=2 5. As part of the response you again get the metadata including the totalCount - property, but this now tells you that the total number of results are 32. Meaning that two new customers have been added or changed status to Active by another user         "metadata": { "totalCount": 32 }         6. This means that you now have to make a total of 4 requests to get the complete result-set. (10+10+10+2). This shows that your client should always keep track of the total number of results received and the total count of results available to make sure that you always get the complete result-set. The following code-example represents a possible implementation of this.           def get_all_active_customers(): page_size = 10 # The pageSize we want to use nest_page_number = 1 # The next page to get, initial value = 1 results_recieved = 0 # The number of results we've recieved total_count = 1 # The total number of results available #If we've revieved less than the total number of resultes, we make a new loop while results_recieved < total_count: response = request.get('https://integration.visma.net/API/controller/api/v1/customer', params={ 'status': 'Active', 'pageSize': page_size, 'pageNum': next_page_number }, headers={ 'Accept': 'application/json', 'Authorization': 'Bearer' + token, 'ipp-company-id': company_id, 'ipp-application-type': 'Visma-net Financials' } | ) if response.status_code == 200: result = json.loads(response.text) # Decodes the recieved JSON # {handle the results} # Increments the number of results recieved by the number of results recieved by this request results_recieved += result.len total_count = result[0]['metadata']['totalCount'] # Updates the total_count variable with the current total count of results next_page_number += 1 # Increments the next page to get by 1       Reference:   www.visma.no/erp/api/dokumentasjon/paging Enforcement of pagination on API endpoints and change of maxPagesize - September release (8.25)

Visma.Net Integrations - API Client Configuration In this document we will go through what needs to be done after you completed your Visma.Net Integration certification.  Redirect_URI The first thing you need to do to configure your API client is to set up a redirect_URI.  Redirect URIs are a critical part of the OAuth flow. After a user successfully authorizes an application, the authorization server will redirect the user back to the application with an authorization code in the URL. Because the URL will contain sensitive information, it is critical that the service doesn’t redirect the user to arbitrary locations.    Due to this, it is required to specify one or more redirect URIs when you register your integration with Visma.Net. For production, it is required that the provided URI is set up with HTTPS.  When you have a redirect URI this should be sent your partner service in order for you to get your Client_ID and Client_Secret. When this has been processed, you will receive an Activation email for your registration, the link to activate your Client_Id will be active for 5 days , so make sure to do this when the email is received:     API client types For Visma.Net there are two client types available, API “ test client ” and “ production client ” (also known as live) Test Clients All new API clients are generated as the type “ Test ”. In the test client there is a limit to the allowed calls per hour, which is set  500 calls/hour . When you are ready to go live with your integration you need to contact your partner service to get access to the API production client type.  Production Clients In the Production Client, the limit for calls  is ​15.000 calls / per hour & per company (since version: 8.25)

Using webhooks can significantly improve the performance of your integration. With webhooks you can subscribe to changes and actions that happens in Visma.net and trigger functionality in your application.  This article explains how webhooks works, and how you can implement this.

Setup up your user rights To be able to use Visma.Net API you need to make sure your visma user have the correct roles on the Financials company you want to use it for. Login with your Visma.Net Account : https://signin.visma.net and g o to Admin Panel. Visma.Net Admin To be able to edit the access rights you need to be logged in with a user with “Customer administrator” role. To set your rights, click on Visma.Net Financials in the top left corner and choose Admin.   User and roles When you have accessed Visma.net Admin click on “User and roles”. Head to the “User” tab. Search for your user name and click your name. Company access and rights If the company you want to edit roles for does not exist in the list under your username, click the “Add access to” menu and look for the company you wish to add.      Find the company you want to edit roles for.     On the line for the desired company, press the field for “Financials” and add the roles “Financial Administrator” & “Financials User”.   Swagger Our Swagger is a good point for you to start using the API.   Connect to your Visma.Net account Authorize and get a VNF token to use in Swagger. Click “Authorize” on the right side of the interface.     Tick the box for “financialstasks” and press “Authorize”     You will be directed to a Visma.net login, enter your credentials and sign in.(If you are not asked to enter your credentials but get directed to the next step straight away, please clear your cookies in your browser and retry)     Allow Visma.net Integrations to connect to your account.     When you have allowed the connection you see that you are now authorized in Swagger. Close the window and proceed to use Swagger.   Start using Swagger The first thing you need to do is check what companies your visma.net financials user have access to. You can find the names and Ids via the “Context” endpoint. Scroll down to the “Context” endpoint and expand it.     Expand the first GET method - Get the companies available for this token, and press “Try it out”.     You will now see a button, “Execute”, press it and you’ll notice the result below will have updated to show your available companies. You’ll also see the request URL.     In the list, decide which company you want to use and copy the “id:”, this is the Id you will add to your “ipp-company-id” header when you are making requests. For now scroll back up to the top and paste the ID in the field “ipp-company-id”. When you have filled this field, the requests you execute via Swagger will target that company.     We also recommend taking a look at : OAuth 2.0 Authorization Flow  

Manage environments Creating a new environment You can create a new environment from the: Manage Environments icon New button Launch screen Manage environments icon Click "Manage Environments" icon in the upper right corner of the Postman app.     Select “Manage Environments”. Click the Add button. New button In the header toolbar, click the New button or click the “Gear” Manage Environments icon   Click "Environment" and enter a name for the new environment.   Add the variables you want to save as key-value pairs.   Click the Add/Update button. Manage Environments to change the values with your own   base_uri :currently pointing to API environment < https://integration.visma.net/API > client_id : The client identifier given to the client during the Application registration process. client_secret : The client secret given to the client during the Application registration process. redirect_uri : (CallbackURL)The Application’s callback URL that’s registered with the server. If not provided, Postman uses a default empty URL and extracts the code or access token from it. company_id : Financials companyId that will be used on API calls   scope: The scope of the access request { financialstasks } state: An opaque value that prevents cross-site request forgery auth_URL: The endpoint for authorization server, which retrieves the authorization code.< https://integration.visma.net/API/resources/oauth/authorize > Access_Token_URL: The endpoint for the resource server, which exchanges the authorization code for an access token. < https://integration.visma.net/API/security/api/v2/token >     oAuth2 OAuth 2.0 is an authorization type that enables you to approve an application that contacts another application for you without exposing your password. To use the OAuth 2.0 authorization in Postman In the Authorization tab , select "OAuth 2.0" from the TYPE drop down menu. From the "Add authorization data to" drop down menu, select either "Request URL" or "Request Headers". To set the authorization parameters for a request, you have three options: Click the Get New Access Token button. The screen appears.  Enter the appropriate values, click the Request Token button to populate the "Access Token" field, and then click the Send button. In the "Access Token" field, enter a token, or an environment defined variable, and click the Send button. In the "Available Tokens" drop down menu, select an existing token and click the Send button.     Get New Access Token After clicking the Get New Access Token button , Postman brings the following screen where user should fill out the parameters.     The values used here are the variables defined in the environment. After filling the parameters user needs to click Request Token button.   You will be directed to a Visma.net login, enter your credentials and sign in.     Allow Visma.net Integrations to connect to your account.     After you click the Allow button and if entered data is correct, you will see the Postman window that has the token. By default Postman expects to find a field named: access_token in the response. Since the Visma.Net response contains a field named  token , instead of access_token , Postman cannot auto-detect it as an access_token     Copy the value of token , close the MANAGE ACCESS TOKENS screen and paste it in the Access Token field.       We also recommend taking a look at : Connecting your Visma.Net Financials company to the API OAuth 2.0 Authorization Flow

In this article we'll review an error message that can be returned when invoking POST > Timecard operation via Timecard Endpoint as well as how to resolve this issue. Timecard endpoint is corresponding with "Employee time card" module in the Visma.Net ERP. (Document View "ScreenID=EP305000"  / Module View ScreenID=EP406000 )   Employee field indicates the employee's reference ID that who we want to create a time card for. The correspondent field in the API POST/PUT DTO is  "employee": { "value": "string" },   Based on your Financials ERP Company setup , The ID of the currently signed-in employee is selected by default on the identifier of the employee whose time cards you want to manage. If your Visma.net User which is used while generating an API Token isn't member of a group that is not hierarchically higher order in the company tree than the desired Employee ID  you want to create a time card, TimeCard POST operation returns the following error: "message": "You cannot create timecards for the selected user. Please review the company tree." The same scenario is valid for ERP UI as one cannot select different employee unless above-mentioned settings are configured. Since this is related to your Financials ERP Company configuration, you need to adjust organization/company tree setup. In order to be able to configure this, please follow the instructions below. 1) Workgroup assignment for the Employee Go to Company Tree (ScreenId=EP204060)  Click your Company Name on top left Add a group by clicking (+) under List of Groups Add a Group Member  Update Tree Save                   2) Continuing with, Create a new group under the recently created one.  Click Test Group on the hierarchy tree (left)  Add a group by clicking (+) under List of Groups Add a Group Member (That is different from your current Login, this employee must be registered in the company) Update Tree Save                 3) Then select newly created group e.g (A Group) and click (=>) right arrow, this will give transaction access to your current user on the users these grouped below in the hierarchy.                     4) Now this employee can be selected / used with both UI Employee Time Card and API.

  You can get a recently created object ID by looking into the Response Headers{Location} of the HTTP Response Headers. HttpResponse.GetResponseHeader("location"); This is one of the Response Headers (LOCATION) that API returns after each successful POST Operation which contains created object ID. public string readLocation(string json) { string[] headers = new string[2]; string strResponse = string.Empty; string location = string.Empty; var httpWebRequest = (HttpWebRequest)WebRequest.Create(endPoint); httpWebRequest.ContentType = "application/json"; httpWebRequest.Method = httpVerb.POST.ToString(); httpWebRequest.Headers.Add("ipp-company-id", "<CompanyID>"); httpWebRequest.Headers.Add("ipp-application-type", "Visma.net Financials"); httpWebRequest.Headers.Add("Authorization", "<token>"); using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream())) { streamWriter.Write(json); streamWriter.Flush(); streamWriter.Close(); } var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse(); using (var streamReader = new StreamReader(httpResponse.GetResponseStream())) { var result = streamReader.ReadToEnd(); headers[0] = httpResponse.GetResponseHeader("location"); headers[1] = httpResponse.GetResponseHeader("date"); strResponse = ("ID: "+headers[0].Substring(headers[0].LastIndexOf('/') + 1)+" // Date: "+headers[1]); //Seperate Resource URL - Created Object ID } return strResponse ; } } Disclaimer The sample code on Visma Community > Visma.Net API is provided “AS IS” and any express or implied warranties, including the implied warranties of merchantability and fitness for a particular purpose, are disclaimed.

When posting documents with subaccounts, some times you might encounter errors that look like this: “Error: (.*) of Subaccount do not exist."   To troubleshoot this please have a look at your Segment Key/Value setup of the dimension “SubAccount” ( ScreenId=CS202000&DimensionID=SUBACCOUNT )     Clicking on the “Segment ID” will lead to the screen showing your values for that Segment Key:     If you have validation activated for your Segment Key’s, you need to set up the combinations you want to be using in the SubAccounts screen( ScreenId=GL203000 )      

What is OAuth 2.0 Grant Type? In OAuth 2.0, the term “grant type” refers to the way an application gets an access token. OAuth 2.0 defines several grant types, in Visma.Net Integrations the grant type used as of today is “Authorization Code”. Each grant type is optimized for a particular use case, whether that’s a web app, a native app, a device without the ability to launch a web browser, or server-to-server applications.   The Authorization Code Flow The “Authorization Code” grant type is generally used by web and mobile apps. It’s different from other grant types in that it requires the application to open a browser to initiate the flow. Therefore the client application has to be able to interact with the users browser and receive incoming requests from the authorization server.  The flow is split up in two parts: The application starts an authorization code request. The application opens a browser to send the user to the OAuth server. The user sees the authorization prompt and approves the app’s request. The user is redirected back to the application with an authorization code in the query string. The application starts an access token request. The application requests an access token with the authorization code provided in the previous step. The OAuth server exchanges this authorization code for an access token Getting the User’s Permission The point of using OAuth is to enable users to get access to the parts of the Application that they need. To be able to do this the application first has to decide what permissions it is going to ask for, then send the User to a browser to get their permission to do this. To start the flow the application constructs a URL like the following and opens a browser to that URL.   GET https://integration.visma.net/API/resources/oauth/authorize ?response_type=code &client_id={yourApiClientID} &redirect_uri={yourRegisteredRedirectURI} &scope=financialstasks &state={randomStringGeneratedByApplication}   Here’s each of the query parameters explained: response_type=code - This tells the authorization server that the application is initiating the authorization code flow. - This field is mandatory and has to be “Code”. client_id - The public identifier for the application. - This field is mandatory and is obtained when registering for Visma.Net Integrations redirect_uri - Tells the authorization server where to send the user back to after they approve the request. - This field is mandatory and must match the URI you registered for Visma.Net Integrations scope - One or more space-separated strings indicating which permissions the application is requesting. - This field is mandatory and case sensitive, it has to be financialstasks state - The application generates a random string and includes it in the request. It should then check that the same value is returned after the user authorizes the app. This is used to prevent CSRF attacks. - This field is recommended for the reasons stated previously When the user is redirected to the authorization server they will be prompted to enter their credentials to allow the applications request.   Redirect back to the Application If the user approves the request, the authorization server will redirect the browser back to the redirect_uri specified in the request, adding a code and state to the query string. For example, the user will be redirected back to a URL such as: https://yourApplicationLivesHere.com/redirect ?code={authorizationCodeGeneratedByAuthServer} &state={randomStringGeneratedByApplication}   The state value will be the same value that the application initially set in the request. The application is expected to check that the state in the redirect matches the state it originally set. This protects against CSRF and other related attacks. The code is the authorization code generated by the authorization server. The lifespan of this code is 10 minutes. Exchange the Authorization Code for an Access Token The second part of the Authorization Code flow is to exchange the Authorization Code the user just received for an Access token. The application makes a POST request to the token endpoint. There are two ways of doing this, HTTP Basic authentication and sending the client_ID and client_Secret in the request body. Both ways require a couple of parameters. Here’s each of the query parameters explained: grant_type=authorization_code - This tells the token endpoint that the application is using the Authorization Code grant type. - This has to be “authorization_code”. Code - The application includes the authorization code it was given in the redirect.  redirect_uri - The same redirect URI that was used when requesting the code.  client_id - The application’s client ID. - This is the ID obtained when registering for Visma.Net Integrations. client_secret - The application’s client secret. This ensures that the request to get the access token is made only from the application, and not from a potential attacker that may have intercepted the authorization code. - This is the secret obtained when registering for Visma.Net Integrations. Please note: All these fields are mandatory. 1. HTTP Basic authentication The HTTP Basic authentication scheme is the preferred way and we encourage all clients that can utilize this authentication scheme to use it. It is done by providing an Authorization header on the request:   Authorization: Basic XXXXXXXXXX= - The value of the Authorization header is a string composed from the authorization method a space(“Basic “) followed by a Base64 encoded string obtained from combining client_ID and client_Secret separated by a colon(client_id:client_secret). Example of this can be seen below: Request Header: POST https://integration.visma.net/API/security/api/v2/token Content-Type: application/x-www-form-urlencoded Authorization: Basic Y2xpZW50X2lkOmNsaWVudF9zZWNyZXQ= Request Body: grant_type=authorization_code& code={authorizationCodeGeneratedByAuthServer}& redirect_uri={yourRegisteredRedirectURI}& 2. Request body The second option for the client is to send it's client_id and client_secret to Visma.net Integrations in the request body. This option should be used by clients that cannot utilize HTTP Basic authentication directly. Example of this can be seen below: Request Header: POST https://integration.visma.net/API/security/api/v2/token Content-Type: application/x-www-form-urlencoded Request Body: grant_type=authorization_code& code={authorizationCodeGeneratedByAuthServer}& redirect_uri={yourRegisteredRedirectURI}& client_id={yourApiClientID}& client_secret={yourApiClientSecret} Please note: All the request parameters sent to https://integration.visma.net/API/security/api/v2/token must be sent on request body. Even though the entire transmission is encrypted when using HTTPS, it is not recommended to send sensitive information (password and client_secret) in the URL as query parameters. The URLs are stored in web server logs which means that your sensitive data is saved in clear text on the server. The token endpoint will verify all the parameters in the request, ensuring the code hasn’t expired and that the client ID and secret match. If everything checks out, it will generate an access token and return it in the response. A successful response will look like this: Response headers: HTTP/1.1 200 OK Content-Type: application/json Response body: { "token": "1f729814-1a98-4c8e-860b-76ec004742f5", "token_type": "bearer", "scope": "financialstasks" } Now the client can start using the token and token_type to make requests through VNA against Visma.net Visma.net Financials resources. Please note: Once generated, the token currently does not expire; the token can be used for making subsequent calls towards the exposed endpoints. A new token should not be generated before making a new call; the token is not connected to the session.
