Introduction to OAuth 2.0 Integration

OAuth 2.0 enables your Visa Acceptance Solutions merchants to securely grant your web-application permission to perform actions on their behalf, such as accessing their customer data and processing transactions. As a technology partner, you can integrate OAuth 2.0 into your web-application through Visa Acceptance Solutions. When your integration is complete, Visa Acceptance Solutions authenticates merchants for you, ensuring that your web-application only performs actions authorized by the merchants. This authentication method securely connects your web-application to the merchant account without the need to receive or store sensitive merchant credentials in your system.

This guide explains how you, a technology partner, can set up and enable OAuth 2.0 for your web-application.

IMPORTANT

OAuth integration through Visa Acceptance Solutions is in the pilot phase. To join the pilot program, and to know which API requests are OAuth-enabled, contact Visa Acceptance Solutions support:
