Hello,
I am trying to integrate with Apple Business Manager to import mobile device data into the CMDB. The ABM API uses OAuth2 with JWT for authentication, and requires that the client assertion be signed with the ES256 algorithm.
I followed this post to generate the client assertion. When I try to use the client assertion to retrieve an access token, I get the error invalid_client.
Has anyone successfully integrated with the Apple Business Manager API?
