Hi,

I'm using PHP and followed the step by step guide, but am getting the following error message when trying to make my first call using the GetCampaigns.php script on a test account i've set up.

Any ideas?


Thanks!

Hi Eliot,

Could you tell me the type of OAuth flow used in your application? This error generally occurs if the access/refresh token passed in the request is incorrect/invalid. To verify, you can obtain the access token being used for the request, then pass that through this tokeninfo endpoint to retrieve the token details. Could you try generating a new refresh token and retry the request?

Thanks,

I'm using 'Installed Application' and trying to connect to the test account at CID level within my Test account MCC. I'll try getting a new refresh token now.

Thanks,

Eliot.
