We are developing a fulfillment app to get data for orders from Shopify into our fulfillment system. I am able to get the orders but when I post a fulfillment I am getting a strange response shown below.
I am using Postman for testing then building it out one API at a time.
The Order ID I am using is 4606998708436 which should be valid based on this…

With this body…
{
"fulfillment": {
"location_id": 66633203924,
"tracking_number": "123456789",
"tracking_urls": [
"https:\/\/shipping.xyz\/track.php?num=123456789",
"https:\/\/anothershipper.corp\/track.php?code=abc"
],
"notify_customer": true
}
}
This is the response I am seeing in Postman…
When I copy the URL from the continue href I land on this page…
Then I will select my account and land on this page…
I really have no idea what I am doing wrong here but tried to give as much info as possible. Anyone have any idea what is going on here? I have even tried creating a second private app with new API keys but the same thing happens get requests for Orders and Locations both work but then fail on the post to fulfill an order.
