> **TIP:** Be sure to run the requests **in order**. This collection uses [Postman variables](https://learning.getpostman.com/docs/postman/variables-and-environments/variables/) to connect each step to the next one, so you may get errors if you run them out of order.

## ShipStation API Reference

This collection contains sample requests for *every* ShipStation API endpoint. It's great for reference purposes, or to see a birds-eye view of all of ShipStation API.

In addition to this collection, we also have [API definitions](/apis/shipengine/docs/getting-started/tools#api-definitions) in various formats. These also include every ShipStation API endpoint.

#### Instructions

1. **Run in Postman**
Click the following button to automatically open the collection. [![Run in Postman](https://run.pstmn.io/button.svg)](https://app.getpostman.com/run-collection/2261346-0abc3d46-f996-40bd-8763-4edf28304864?action=collection%2Ffork&collection-url=entityId%3D2261346-0abc3d46-f996-40bd-8763-4edf28304864%26entityType%3Dcollection%26workspaceId%3De5d9107f-16a5-4b34-800a-db42aca71bc2)
2. **API Key**
Select the "*ShipEngine*" environment in Postman, which has your API key.
3. **Send Requests**
Start with the "*Carrier Integrations*" folder, and the "*List your carriers*" request. Be sure to run requests **in order**, since many steps of the walkthrough rely on previous steps.
4. **Descriptions**
Each folder and request has a description explaining what it does. You'll need to click the arrow next to the request name to see the description.
5. **Visualizations**
Rather that viewing raw JSON responses, try [Postman's Visualize view](https://learning.getpostman.com/docs/postman/sending-api-requests/visualizer/) to see the API response in a friendlier format.
