Can no longer post offline conversions to Adwords

[Sofia Agboatwalla]

I was using the  Adwords API for sending offline conversions to Adwords. They were going through and I could see them under Conversions in my Adwords accounts.

Then suddenly, I am seeing this error :

AuthorizationError.USER_PERMISSION_DENIED @ ; trigger:'']

What could have been a possible cause?

Hi Sofia,

Did your account structure or login access change recently? Does the conversions you are uploading belong to an account that you (i.e. the account for which you have OAuth2 accessToken) have access to?
