We now have a way to check order status for an order that you've submitted.
Click here: https://www.trepstar.com/http-gateway-api.asp then scroll down to the getOrderStatusByInvoice section
Summary:
Retrieve order status from a previously submitted order.
Your software will initiate an http get or post request (a webhook) to a TrepStar HTTP Gateway URL (https://www.trepstar.com/custdataXML.asp). The response will be in XML format.
The getOrderStatusByInvoice function will retrieve the status of a previously placed order. The status will contain delivery status, and a shipping tracking id if applicable. Each http call to the service results in a single XML response.
Input: Invoice used when creating the order (the invoice you specified when ordering).
output: XML Response
