Can I use my own payment gateway and integrate it with Zoho Subscriptions using your API?
No, it’s not possible to integrate and configure your own payment gateway.
Zoho Subscriptions provides Payment Gateway after verifying all the security aspects and compatibility with our systems.
Hence we don’t allow custom Payment Gateways to be integrated and configured as of now. If you’ve any Payment Gateway you want us to consider for integration, put in our user voice forum.
