Since the Visma.net ERP API was released authentication has been handled by an implementation of the OAuth 2.0 protocol called VNI. This has served us well, but it has some limitations that makes it somewhat cumbersome to work with both for you as developers and internally in Visma.   Since the release of the Visma.net ERP API, the importance of APIs and number of integrations has grown rapidly and the amount of traffic we have received on the API has doubled year over year. More importantly, the requirements to securing the APIs are constantly increasing, and protecting our customers' data is always a top priority for us.   In the last few years we have developed our Visma Connect product into a state of the art implementation of the OAuth 2.0 protocol, including surrounding tools like the Visma Developer Portal and Visma App Store.   Using Visma Connect as the authentication provider for the Visma.net ERP API is therefore an important step to keep your integrations and our customers' data secure.     Why should you switch? There are multiple reasons why you should upgrade your applications to use the Visma Connect authentication provider. Visma Connect is more secure than VNI. Visma Connect supports the Client Credentials-flow, this makes it possible to create machine-to-machine integrations. Handling of your application is done self-service in the Visma Developer Portal, this includes creating new applications, managing credentials (ClientId and Secret), managing token lifetimes, scopes and much more. The new next generation APIs for Visma.net ERP, like the Sales Order Service uses Visma Connect, therefore when you switch to Visma Connect for your application you can reuse the same authentication.   All new integrations should use the Visma Connect authentication mechanism. The existing VNI authentication-mechanism will be deprecated during 2023, so please consider changing your integrations already. The attached PDF is a detailed guide on how you could migrate your existing integrations to use Visma Connect.
