Fulfillment - Required parameter missing or invalid

New Member

I am getting an error message when posting a Fulfillment REST request with the following parameters:

  "fulfillment": {
    "location_id": {a valid location},
    "tracking_number": null,

Per the documentation (https://shopify.dev/docs/admin-api/rest/reference/shipping-and-fulfillment/fulfillment#index-2020-04) the only required field is the 'location_id'.

What am I missing?

Hey @igreisman,

Kindly provide the X-Request-ID value from the response headers of your call, and I'll try to get more information from our logs.
