Server-to-Server Integration — Overview

If you need more customization, flexibility, and efficiency for your collections — bank transfers in NGN, or mobile money in GHS, KES, UGX, RWF, TZS, and XOF— this integration is built for you.

This solution is for businesses that need full control over their payment processing workflow. It provides a direct, app-native API for initiating payins across all supported currencies and payment methods through a concise set of endpoints.

With Startbutton's S2S (server-to-server) integration, you build your own UI, tailor your payment flow, and control the customer experience end to end.

Choose the integration that matches your payment method:

• S2S — Cards
