Working with Visa APIs

The steps below outline the end-to-end process around engaging with our APIs and building a new project. Explore the details below.

Visa is with you every step of the way

Visa Developer offers a set of Application Programming Interfaces (APIs) that gives you the ability to incorporate Visa functionality into your projects.

We are excited to work with you to innovate on the next generation of applications using Visa and our proprietary APIs. Each step below outlines what it takes to get your project off the ground. From finding a use case that meets your needs, to launching that project to your customers.

Create a Project

Once you register on the site, you get access to our sandbox environment that allows you to start engaging with our sample code and APIs. On the account-specific dashboard, you will have a place that you, or others on your team, can all work together to build something amazing.

Learn what authentication code you need for your project based on the APIs you are using. We have both tips and tricks, as well as sample code that can help get you going with both Two-Way SSL or X-Pay Token methods.

Managing Certificates

For all Two-Way SSL (Mutual Authentication) projects, inbound credentials have an expiration date. Once it is about to expire, you can request a new set of credentials (this is only available in the sandbox environment). You can also access the Visa Developer Platform public certificates used to identify Visa API endpoints.

Message Level Encryption

The next step in the process is to find out if your project API requires message level encryption to get going. Note: not all APIs need MLE today.

Outbound Configuration

A project created with certain APIs on Visa Developer enables you to register the URLs on which you want to listen to events using Outbound Configuration. The callback triggers an HTTP POST to the configured URL when an event occurs. The client can then be notified on the URL and has the flexibility to take appropriate action on the notification.
