# About Server-to-Server JSON V1 Integration

> Our default [Server-to-Server integration](/payments/payment-gateway/s2s-integration/redirect) is simple.

* The payment creation request returns a variety of responses. All of these responses need to render on your customer's browser to push the payment forward.

* These responses result in redirecting the browser to a bank or gateway page to complete payment authentication.

However, if you want more control over how the customer is redirected, you can use the JSON API endpoint. The response to this endpoint contains only the necessary details and information about the next steps to be taken. Your integration is required to handle different flows to be able to process a payment.
