I am Developing a new warehouse integration for the company I work for as there was not existing solution.
I have gotten almost every feature to work including fulfillment request and stock requests and even registered a carrier service for real time shipping rates however for some reason i can not get the /fetch_tracking_numbers call to fire from shopify according to the documentation
"Once per hour Shopify will make a request to this endpoint if there are any completed fulfillments awaiting tracking numbers from the remote fulfillment service."
however I have added logs to the call so i can trouble shoot it however it seems that shopify never makes this call to the server.
The product Vairent is set to the custom fullfillment company however I am still not getting any calls to my server from shopify for tracking numbers.
I tried both completing the fullfillment and leaving it as pending just to see if I get a call from shopify but I am still not getting anything.
If I visit the url myself i can fire the code (logs and all) however it doesn't seem like shopify is doing so in the install I made sure to provide a valid call back url (thats why fetch stock works fine) and set the tracking support field to true but still nothing
There are also no log information on failed attempts in the orders event stream
