In Entra ID, how to access the MS Saleshub (Dynamics CRM) via API from Tenant A to Tenant B

Question

Hello, I would like to use incoming data from Entra ID from tenant A to use this data for an entry in tenant B in the Saleshub. I already have an application in both tenants that is configured as a multitenant. Tenant B has Dynamics CRM user impersonate rights. Tenant A has no rights. If I now try an API call with the ID's of App Tenant A, I get the error message, "The user is not a member of the organization." How should the apps for this case be structured? Greetings

Hello @Fabian Homann , in order to obtain data from tenant A, you need to access authenticate as principal (user or guest or application/service) of tenant A. The "The user is not a member of the organization" error could be happening due to you trying to access tenant B with a non-guest user of tenant A or vice versa.

Fore more information take a look at:

• Properties of a Microsoft Entra B2B collaboration user
