We have just launched our integration with Visma.net but are having problems onboarding our first users. We redirect them to: https://connect.visma.com/connect/authorize?client_id=isv_boardeaser&redirect_uri=https%3A%2F%2Fapp.boardeaser.com%2Fintegrations%2Fvisma_net&response_type=code&scope=vismanet_erp_interactive_api%3Aread&state=state (With some real state, I removed it in this example) They are prompted to login and select their organization, then they are redirect back to our app with a code and the state. We make a POST request to https://connect.visma.com/connect/token username: isv_boardeaser In the body we include: code - that we receive from you in the callback url grant_type=authorization_code redirect_uri=https://app.boardeaser.com/integrations/visma_net The response is 400 with body {"error":"invalid_request"}. Do you have any idea what might be going wrong with this client? We have been successful with connecting it to our own ISV-account.
