Which Piwik version are you using now and which one did you use before? From what I see there were no changes to this method over the last months.

How do you call this API method? Via JavaScript? PHP? Do you actually get a success message as a return from the API? Can you post the response here?

Which Piwik version are you using now and which one did you use before?

I am using version 2.15.0. I don’t recall which version I was using before.

From what I see there were no changes to this method over the last months. How do you call this API method? Via JavaScript? PHP?

I use Ruby on Rails to make the call.

Do you actually get a success message as a return from the API? Can you post the response here?

Yes. I do get a success message. The message is below.

result
success message="ok"/
/result

I also tried testing the call by attempting to set user access for a user that doesn’t exist and it returns the correct error message below.

result
error message="User 'mc_user_ulhe349mx35' doesn't exist."/
/result

However, when I do another test setting user access for a website that doesn’t exist, I get a success message again instead of getting the appropriate error message.
Thank you.

Setting user access for non-existing websites is covered here: #8697

I had a look again at the code and it should work fine. Does it work for you when you change permissions in the UI itself?

Maybe you can let us know how you call it (the parameters that you are sending to that API method), what you expect to happen and what actually happens? This way we can maybe reproduce it.

I can change access thought the UI just fine. Only through the API is it not working.

The URL I am sending to Piwik is below. I removed the token auth info since this is a public forum but I am using a super user token auth. It returns success message but user access does not get set. Thanks.

I just tried the exact same call just with a different siteId and it works just fine (created a user having the same login name). Do you have access to the database? Maybe the permission is actually set but something else is not working? You can verify in the access or piwik_access MySQL table.

Just to be sure: In the users manager, do you select the website 707 to check whether permissions were set?

oh shoot. sorry about that. That was it. I needed to select the correct website in Users manager to see the access set. Thank you!

No worries :)
