When attempting to assign a user to an application, the following error occurs:

An error occurred while assigning this app.
Automatic provisioning of user <userName> to app <appName> failed: com.saasure.application.generic.client.AppApiException: javax.ws.rs.NotAllowedException: HTTP 405

The above error was reported on the Zuora application.

• Provisioning
• Zuora
• Okta Integration Network (OIN)

The request method used for the resource is rejected because the credentials used to connect to the API were invalid.

Ensure that the API credentials used for the application integration have administrator-level access to the resource. This may involve checking the application's permission settings or the API key configurations. Verify that the credentials have the authority to perform the required actions, such as user assignment and provisioning.

It is recommended to reach out to the Service Provider to further investigate the error encountered.
