Issue - "error": "invalid_grant", "error_description": "Bad Request"

Hello,

I ended up with the error below when I tested GetCampaigns.php from the PHP client library.

It worked fine with my test account, but went wrong with the production account.

Any help is appreciated.

Thank you.

Hi,

This error occurs because of a mismatch of credentials and tokens. I would recommend clearing the cache and using the newly generated refresh and access token pair.
