[SOLVED] Cant get members for my Campaign via oauth2 V2 in PHP

I’m trying to get my campaign information via the new BETA API via this link:


The ******* replaced with my numeric seven digit campaign ID of course.
However, it gives me following error every time:

Unauthorized, The server could not verify that you are authorized to access the URL requested. You either supplied the wrong credentials (e.g. a bad password), or your browser doesn’t understand how to supply the credentials required.

I’m certain I send the correct token since the old API works fine with the link:


What could be the problem?

Thank you for your help!


I figured out that you MUST register a v2 client for it and it works now!
Maybe this should be stated more clear in the documentation, as it is only mentioned in a side note at the moment and it sounds like its optional.

How can I add members to a campaign using API.
I have different campaigns and want to subscribe a user to a campaign of $5, I have 3 campaigns.

Hi @logixsol! You cannot do this at this time, the members endpoint is read-only. Feel free to reach out if you have any more questions!
