Fulfillment API returns 201 Created but shipment not reflected in Seller Hub
Hello,
We are encountering an issue when creating a shipment using the eBay Fulfillment API.
The request to create a shipping fulfillment returns a 201 Created response, indicating that the request was successfully processed. However, the shipment information does not appear in the eBay Seller Hub order details, and the order still appears as not shipped on the marketplace platform.
Below are the details of the request:

Despite the successful API response, the fulfillment does not appear in Seller Hub and the order status is not updated.
Could you please help us verify whether the fulfillment was properly registered on your side or if there is any issue with the request?
Thank you for your assistance.
