In-App Payment Solutions
Use a Square SDK for mobile devices to take payments in a mobile application for Android and iOS platforms.
The In-App Payments SDK provides a mobile application client and a customizable card payment interface that allow buyers to make purchases. The SDK generates a secure payment token that gets passed to the server backend, which creates the payment using the retrieved token.
Use the Quickstart sample application to start building with the In-App Payments SDK. For more information, see In-App Payments SDK Quickstart.
