Postman collection

Download the collection and import it into Postman or Bruno:

Download public-api-v1.postman_collection.json

Collection variables (edit before running):

Variable	Description
baseUrl	API host: https://api.saveonexpress.ca (production) or https://api.dev.saveonexpress.ca (development)
apiKey	inex_api_{32 hex}
rateResponseId	Set automatically after Rate (or paste manually)
orderId	Set automatically after Ship
labelType	Default PDF; updated from ship/list labels

Use the Flow (run in order) folder for rate → ship → labels → track → cancel. The Cancel folder can be used on its own when you already have an orderId. For label download, enable Automatically follow redirects in Postman settings if you want the client to fetch the S3 file after 302.
