Create REST API Keys

REST API keys are used to enable secure communication between the merchant and Visa Acceptance Solutions when using REST APIs. To enable payments using the REST API, see: Getting Started with REST

The REST API supports two types of security keys:

P12 certificate
for using JSON Web Token authentication. See Create a P12 File.

Shared secret key
for using HTTP signature authentication. See Create a Shared Secret Key Pair.

REST API keys expire after 3 years.

Security keys can be used to make any request, including payments. Treat your security keys as you would any secure password.

You must use separate keys for the test and production environments.

When you sign up for a Sandbox account, your confirmation email contains a key and shared secret key for HTTP Signature authentication.

For more information about the REST API, see the REST Getting Started Guide.

Create a Shared Secret Key Pair

Follow these steps to create a shared secret key pair.
