The standard UPI tracking function is a simple HTTP callback.
For defined events in the creation process, status changes with definable parameters are transmitted to a URL that they announced.
Below are two examples of a status change (to “Cancellation”) based on the order_number 999999
as well as the customer_number 1234567.
HTTP JSON callback

HTTP callback
https://your_url.de/tracking.php?order_number=999999&item_group_name=flyer&customer_item_name=myfirst order&actual_state=order_stati_7000_4&shipment_number=1&customer_number=1234567
This PHP call writes a “tracking.log” in the same directory with the parameters previously defined by you.
