# Postman

Here is our Optty postman for create order flows:

{% file src="/files/tws2gLQ3W3fFifxVJiTm" %}

Pre Requisites

1. Download the postman collection.
2. Replace `webhook_url` in the collection variables to a url you can receive webhook messages on. <https://webhook.site> is an easy way to do this.
3. Go through the Order flow outlined in the Postman collection (Steps 1, 2 and 3)
   1. Follow the redirect URL in step 3 to complete payment and test the other order management end points

This Postman collection is linked to an existing Optty merchant with pre-enabled payment methods. While sufficient for basic testing, more in-depth testing requires signing up for your own merchant account[ here](https://www.optty.com/merchant-account). Once registered, replace the \`client-id\` and \`client-secret\` with your new merchant's credentials in the collection level variables. You will also need to enable payment methods using the Optty credentials linked at the bottom of this page.

## APM Simulation

To ensure a smooth integration, we recommend using the Optty Sandbox APM for the majority of your testing. This tool allows you to simulate the full order lifecycle—from creation to final status—without relying on third-party sandbox environments.

Why use the Sandbox APM?

* Total Control: Simulate specific edge cases (e.g., specific error codes or pending states) that third-party sandboxes may not consistently support.
* Higher Stability: Avoid external downtime or credential issues often found in third-party test environments.
* Faster Iteration: Test complex asynchronous flows (like webhooks) on your own terms.

***

## Third-Party Sandbox Testing

While the Sandbox APM covers most needs, we understand you may occasionally require a "live" simulation within a specific third-party environment (e.g., ZIP AU) to verify the end-to-end redirect experience.

Below, you will find the Credentials required to enable these methods in your Optty Merchant Dashboard and the Test Payment Data needed to complete the checkout on their respective pages.
