Request for Guidance: Customizing Plugin for Local Payments

I appreciate your excellent plugin.

However, I’m encountering an issue with the payment gateway. While your premium extension supports PayPal and Stripe, these options are not available in my country. Is there any documentation or guidance for developers on customizing or integrating a custom payment gateway?

In my country, all banks, including the national bank, offer payment gateways for e-commerce that are compatible with WooCommerce. I’m hoping to find resources to implement this in your plugin.
