Payment Verification with the Connect Widget

Legacy Guide

This guide is for Platform API v2011101. For guidance on the newest version, see Connectivity Integration Guides.

This guide uses our Connect Widget to gather end user’s credentials and fetch the appropriate data to enable payments.

To learn more about the widget, see Connect Widget.

We’ll use our Widget SDK to integrate the widget into your application. For more information on the Widget SDKs, see Implementation Guides. Your integration method depends on whether you’re building a web or mobile application. If you’re building a web application, use our Web Widget SDK. If you’re building a React Native application, use our React Native Widget SDK.

To make this guide easier to follow, we don't cover multifactor authentication (MFA) or OAuth. We have in-depth guides on how to manage MFA or OAuth depending on the product you’re using.
