Step 4: Test and validate your integration

You can begin to test your system's integration using these test cards in your sandbox environment. Each currency requires its own Merchant ID, so if you intend on accepting multiple currencies, you will need to create a new integration for each one.

Once you have completed your integration, please reach out to our Integrations team at dl-integrations.na.isv@worldline.com to validate your integration before pushing your code to production.

Lastly, go live!

When you are ready to go live, book a call with one of our specialists to discuss go-to-market strategies in accepting payment in your software with your sub-merchants.
