-## Overview
-
 SumUp API Payment Switch is a light integration where your app opens the SumUp app to request and execute a payment. This integration approach has been the go-to solution for web аpplications before the platform-agnostic [Cloud API](/terminal-payments/cloud-api) was released.
 
 Your app initiates a request to charge a card, opens the SumUp app on the merchant's mobile device, and we handle the rest. Once the payment has been processed, the transaction result is communicated back, and the merchant is returned to your app.
