PayPal setting up auto-acceptance of payments?

Question

PayPal

Can you please tell me how to automatically accept payment?
This is the case, there is a payment on the site, as soon as the user has paid, the payment has come to the stick, but it must be accepted as soon as it arrived. Since, during this time, the user can use the services of the site, and in fact, return the money as long as they have the PENDING status.
Yes, I will notice this when checking, I will give a ban, and yet, it is necessary to set auto-acceptance of payments, ideally, without the possibility of a chargeback. Since, again, it turns out that the user will come in, use services that are paid, and then charge back the money.
While testing in Sandbox.

well, he can then create a dispute
here only to build an antifraud, accept from confirmed accounts (for the CIS, this is not God knows what, but still better than just a recent map)
