ShipEngine Reference

Reference Docs

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

In addition to this collection, we also have API definitions in various formats. These also include every ShipEngine API endpoint.


  1. Run in Postman
    Click the following button to automatically open the collection. Run in Postman

  2. API Key
    Select the "ShipEngine" environment in Postman, which has your ShipEngine 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 to see the API response in a friendlier format.
