I sell and ship goods. And using DHL Express for delivery. But would my Customers to view the tracking info through my Wix web site and use the one on DHL website.
on the Wix website, would be one Box to input the Tracking-Number provided by DHL, a click and the get the information displayed, collected from the API.
No need to ingrate with Cart, label or orders, ... just the tracking tool.
Already have the API keys available from DHL.
support will be much of help.
