Should you encounter any error during the installation of Shipup's Magento app, you'll find below a few steps that might help getting back on the right track.
Invalid url error
Make sure that the url you're sending is the main url of your store and not one that redirects to your store. Basic syntax errors such as forgetting the "www" part of the url or using "http://" instead of "https://" might be the reason of the error.
Also, the root of the store should be sent, please do not include any custom route:
bad: https://mystore.com/admin, http://mystore.com/soap
Invalid API key or url error
Please make sure you created the webservice role and user with the correct info, and that you correctly linked the role to the user.
I successfully created my app but don't see any package imported
Please verify that the store id provided is the one your orders are registered on. Shipup will only import your packages once per hour (plus once at app creation) and will only import orders where a tracking number can be found (tracking numbers need to be added in the "shipment" tab of the order").
If the above steps didn't fix your problem, feel free to contact us by email or chat (firstname.lastname@example.org) and we'll do our best to help !
