How do we
1. pass customer data to the register app and
2. link that customer data to the order created inside the register app, and
3. then pass that combined customer and order data back to our CallDock app?"
Thank you for your help in clarifying these points.
Best,
Niall
For more context on the app's user flow
1. Customers information is passed to our app and the merchant would then like to create an order for that user.
2. The user is brought to the Register app, where an order is made and paid for. The user is then brought back to our app with the combined Customer and Order data, where further actions are taken with that information.
