# Courier and Postman

> Explore and test Courier’s API using the official Postman collection—fork it, configure environments with your API keys, and start making requests with ease.

Courier's Postman collection is available for everyone who wants to get familiar with Courier's API. We'll help you get started in this guide.

From Postman, you'll need to fork the Courier API Collection into your Postman workspace and create [Postman environments](https://learning.postman.com/docs/sending-requests/variables/managing-environments/) that map to your [API environment keys](/platform/workspaces/environments-api-keys) from Courier.

## Getting Started with Courier's Postman Collection

<Steps>
  <Step title="Install Postman">[Install Postman](https://www.postman.com/downloads/) to get started with Courier's API collection.</Step>
  <Step title="Fork the Collection">Navigate to [Courier's API Postman Collection](https://www.postman.com/trycourier/courier-s-public-workspace/collection/aiy9mtt/courier-api?action=share\&source=copy-link\&creator=38408779) and fork the collection so that you can pull any changes we make to the source collection.</Step>
</Steps>

## Configure your Courier API Key Environments

You can create a Postman environment for each of your Courier environments. You can store your API keys in environment-level variables and easily use them when making API calls with our different endpoints.

You can follow Postman's instructions on how to set up environments [here](https://learning.postman.com/docs/sending-requests/variables/managing-environments/).
