OptimizeMember integrates with most popular payment gateways including but not limited to PayPal, Stripe, Clickbank, JVzoo and PayPro (Dutch).
If you want to integrate a local payment gateway with OptimizeMember, you would require some programming. Please refer to the link below for details:
In case you are not comfortable with coding, please find a developer/programmer that can help you on this matter. They should be able to find general guidance under OptimizeMember >> API Scripting, which has some information on external gateways.
As much as we want to help, we are not able to provide assistance with any 3rd party integrations, as provided in our support policy.
