payment form that's not listed?

Hi...I am making a school registration form and we use a new smart tuition tool for online payments. Can I use a different payment tool? If so, how?

You can use only the integrated payment gateways listed:

What is the name of the payment gateway you need, we can send a request to our second level to have an integration with it, but be aware that the request can be approved or declined, and if it gets approved, there is no estimated time-frame for it's implementation.
