You can chose to pay your affiliates via any of the supported payment methods
We do not support automatic payments via PayPal for multiple reasons
The affiliate has a direct relationship with the merchant ("you"), so it makes sense that they receive payments from you.
It helps you avoid stacking of transaction fees. Merchant > GoAffPro > Affiliates.
We understand that some other apps might support automatic payments, done via the PayPal API with your credentials. However, handing out access keys to a third party is not safe.
You are placing trust in a third party to handle your money. This third party now has access to your entire PayPal account, including funds, transaction history, personal details etc.
Even if the app itself is not malicious, servers can get hacked and data get leaked. In such an event, the unauthorized third party can wreak havoc on your PayPal account.
We at Goaffpro, have decided to trade off better security over convenience.
