Did you try to access that via the browser URL?
If so thats the problem. I just did it via POSTMAN with the appropriate accesstoken and it works just fine.
POSTMAN is a website that makes it easy to test apis. I tested the endpoint via POSTMAN and it worked fine.
I'm having the same issue.
I just rolledback from API version 2023-04 to 2023-01 and it works.
So using PUT to themes gives 404 for the 2023-04 version.
I also tried the new API version 2023-07 which also gives 404.
I can't find any difference in the API documentation, except scopes which I have (and if that was the case should a 401 be returned instead of a 404).
Have you identified the issue?
You can only fill out the form for your application to be exempted. If you still want to use the API to update assets.
