Hello
I am new to shopify and API's. i am trying to update a fulfillment, looking at the document, running the open.json, it changes the status to In_Process, i am receiving The remote server returned an error: (422) Unprocessable Entity.
"https://XXXXXXX.myshopify.com/admin/api/2022-10/fulfillment_orders/5223589642533/open.json"
i have tried a PUT and POST, both return error's
Any suggestions would be appreciated
Regards
John
