Postman API Suite

Use Circle’s Postman collection to send API requests and try CPN APIs.

Circle’s Postman collection provides template requests to help you learn about the Circle Payments Network APIs. These requests run on Postman, an API platform for learning, building, and using APIs. The Postman CPN workspace includes a collection that matches the organization of the API References.

Run in Postman

To use the Postman collection, click the Run in Postman link below. You can fork the collection to your workspace, view the collection in the public workspace, or import the collection into Postman.

• Fork: Creates a copy of the collection while maintaining a link to the parent.
• View: Allows you to quickly try out the API without importing anything into your Postman suite.
• Import: Creates a copy of the collection but does not maintain a link to Circle’s copy.

Authorization

To authorize your session, use Circle’s Postman variable apiKey and add your API key to the environment or collection variables. See Postman’s using variables for details.

You can get an API key for CPN from the CPN Console. Contact your Circle representative to get access to CPN.
