Wordpress - CPA and Point Rewards - how to

Hello guys,
I`m making a website. The idea is that there will be CPA offers and when the user completes them successfully a plugin or something has to recognize this and give them points in their profiles. Do you have any idea with what plugin I can achieve this?
Thank you in advance!

Best regards,
Monika

I suggest looking into MyCred, but you'll have to hack into their code or build your own plugin to do this. I've tried this in the past and it's a headache to do with Wordpress.
