This module makes PayPal’s functionality in WHMCS almost identical to a credit card gateway except that instead of supplying credit card information to a gateway, the module would supply the PayPal reference transaction token to make a charge. Basically, this module acts like a credit card module, but for PayPal.
This module is different than the default functionality that is built into WHMCS which creates a recurring payment profile for a customer.
