How can I automate the event of a new customer paying to join my group, triggering a webhook to notify my team via email/slack/whatever?

We have a good gamification system going in our community where users unlock new content when they reach a certain level. It's been really great overall for promoting engagement... However, it's starting to crop up bit by bit that the quality of content is going down slightly, and some folks are pretty transparently engaging in "point farming." I searched already but didn't find anything... is there anyway to combat this?

I accidentally have affiliate credit for Skool for groups I know I shouldn't have credit for. How can I transfer their affiliate credit?

How can I invite people to join skool so that they'll both get to join my private group AND be added as an affiliate lead when they create their own group?
