Postman Suite

Use Circle’s Postman collections to easily send API requests and try out our APIs.

Circle’s Postman collection holds sample requests for Circle APIs. Run them in Postman, an API client. The Circle Mint workspace has one collection per area: API Overview, Core Functionality, Stablecoin Payins, and Stablecoin Payouts. Folders follow the same layout as the API References.

How To Use It

Run in Postman

Select one of the six Run in Postman links below. You’ll be asked whether you want to 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 having to import anything into your Postman suite. Import: Creates a copy of the collection but does not maintain a link to Circle’s copy.
