Why do I get 403 code when try to approve PR via REST API?

[Dmitrij Abashin]

Hi all!

I add a reviewer to a pull request and then try to approve the PR via 

PUT /rest/api/1.0/projects/{projectKey}/repos/{repositorySlug}/pull-requests/{pullRequestId}/participants/{userSlug}

I use the HTTP token from the user whose userSlug I use in the URL.

But whatever I do I get the error: {"message":"You may only update your own status.","status-code":403}

The product is server, I have no option for this, IDKW.

Please give me a clue, I really have no idea what is wrong here.

I'm also encountering this problem. I can approve PRs just fine through the API with basic user credentials (username/password), but not with repository-level HTTP access tokens. I've tried multiple options for userSlug with no success.
