Retrieve info about a Messenger user

Hi,

Facebook APIs are such a mess… I need your help please :).

I have a Facebook Messenger - Watch Message module. When a user send a message to my FB page, i get an operation and i retrieve the PSID of this conversation :

FB - Watch Messages

Now I’d like to know if it’s possible (using a sequence of FB modules available on Make) to find out if the user who has just sent me a message is a user from a specific FBAds Campaign.

I have many users who send messages to my Fan page, and I’d like to sort out those who come from an FBAds ad.

Is there a module available on Make that lets me know which user(s) have clicked on an ad belonging to a specific campaign?

Thanks in advance for your help.
