Safe referrals

Greetings.
1. I use the referral system in the store. I want to make it safe. How to make a referral replenishment of a wallet after a new member replenishes his wallet by a certain amount? Or how to make a referral replenishment of the wallet after the purchase of a certain product by a new member? Or transfer funds from the wallet of the new member to the wallet of the old member. How to do it automatically?
2. Tell me, how can I make automatic debit from my wallet?
3. Tell me where can I read the documentation?
