Can modify APIs but unable to create revisions

Question

We are using a shared/centralized API Management service within Grundfos and we can update/modify the operations within our existing APIs.

However, we are getting an error when trying to create a revision.

We would like to clarify why creating revisions are not permitted when they are within the same API. Is the permission different from creating revisions?

Answer 1

@Kim Patrick Delos Reyes Thanks for reaching. Can you please confirm what permission do you have on the APIM resource for which you are trying to perform the operation? If you have API Management Service Contributor then you should be able to perform the create revision operation. In case you are using the custom roles then make sure that you are providing the Write permission for the revisions so you can able the revisions on your APIM service.

Answer 2

Kim Patrick Delos Reyes Thanks for sharing the additional context. Based on my understanding, you are using a custom role instead of built-in roles with specific actions, scopes assigned to users instead of whole APIM instance like described in doc: Custom Roles.

For updating and modifying Operations within an API, you need Microsoft.ApiManagement/service/apis/operations/write (or Microsoft.ApiManagement/service/apis/*/write) however, for creating a revision, you require Microsoft.ApiManagement/service/apis/write as referenced in the example in the doc.

For full list of operations and corresponding permissions required, please refer Microsoft.ApiManagement. We will add a note to specifically mention about creating revision in the doc.

I hope this helps with your question and feel free to let me know if any other questions.
