Postman collection

The collection covers health, create payment (full, minimal, 3-D Secure), open a hosted checkout session, lookup, refund, simulated postbacks to your own server, and eight common errors.

  1. Import the collection into Postman.
  2. Set the collection variables baseUrl, merchantIdentifier, apiKey, midName and postbackUrl, or import the staging environment, select it, and fill in merchantIdentifier, apiKey and midName.
  3. Open the folder 0. Read me first and run Health check, then work through the folders in order.

Each request in 5. Common errors breaks one rule on purpose so you can see the exact response your code must handle.
