# Postman collection

> Use Circle's Postman collection to send API requests and explore the Circle Mint APIs.

Circle's Postman collection provides sample requests for the Circle Mint APIs.
Run them in [Postman](https://www.postman.com/), an API client. The collection
matches the layout of the
[API reference](/api-reference/circle-mint/general/ping).

## Run in Postman

Select **Run in Postman** below. Choose one of the following options:

* **Fork**: Copies the collection and keeps a link to the parent.
* **View**: Lets you try the API without importing it.
* **Import**: Copies the collection without keeping a link to Circle's copy.

| Collection          | Link                                                                                                                                                                                                                                                                                                                                                |
