Shopify API - Order Fulfillment/add tracking info call not working?

1 0 1

Hello Everyone - 


Wondering if anyone has run into this before.  We have orders in Shopify and I'm trying to write back to that order tracking info.  When I do, the post call, however, the tracking info is not passed but no error or success message is returned.


Have anyone encountered this before?  Here is the documented calls I'm trying to make:


I've also tried creating a fulfillment, but that returns the same 'no message'.


Thanks for any help/experience you can lend!

Hi There,


would need to see your call(s) to be of more help. I have used this before and it worked without issue.
