Hi there. Thanks for the heads up on this thread.
Regarding payment gateway integrations. I’m sorry but we do not work directly in partnership with any specific payment gateways. s2Member currently integrates with PayPal, PayPal Pro, Authorize.Net, ccBill, ClickBank, and Google Checkout. While we have every intention of integrating with additional payment gateways in the future, we will be adding support for these additional payment gateways on a schedule of our choosing.
If you would like to integrate your payment gateway with the current release of s2Member (on your own, or with help from a WP developer), please consult the documentation made available in the s2Member Dashboard under:
Dashboard -› s2Member® -› PayPal® Options -› PayPal® IPN Integration
› IPN w/ Proxy Key ( optional, for 3rd-party integrations )
Any payment gateway integrated with s2Member will require that payment gateway to POST simulated PayPal IPN’s back to s2Member. The instructions on how to accomplish this have been provided in the aforementioned section of your Dashboard. Please let us know if you have any questions about this.
