# Postman collection

> Every API endpoint, ready to send from Postman.

> **[Download the collection](https://developers.fastcac.com/postman/fastcac.postman_collection.json)**
>
> `fastcac.postman_collection.json`: one folder per area, one request per endpoint.

1. In Postman, choose **Import** and drop in the file.
2. Open the collection's **Variables** tab and set `api_key` to a test key (`fc_test_…`). Every
   request sends it as a Bearer token.
3. Set `registration_id` and the other id variables as you create objects.

`POST` requests send a fresh `Idempotency-Key` each time. Request bodies are real examples you can
edit.

The collection is generated from the same OpenAPI spec as the [API reference](https://docs.fastcac.com/api-reference/introduction.md),
so the two always match.
