Hello Together I would like to generate a fulfillment status in Shopify. As long as I follow the API documentation of Shopify. I get an error message: Bad Request Status 400.
I also tried it in the POST-Request instead of Custom-Request. Write here Error Code 500. I'd appreciate any solution. Thank you.
Here is the Shopify API documentation.
