Hi I hope you are well, I was trying to get a success response with a sample data in the doc by Postman ( https://developer.ebay.com/Devzone/post-order/post-order_v2_cancellation__post.html#Samples) Here is the response I've got [Request] Thu, 16 Jul 2020 09:49:30 GMT
**ServicePostTxnOrderManagementServiceV2Client.PostTxnOrderManagementServiceV2Consumer.HTTP11 is marked down with status APP_AUTO_MARK_DOWN** I don't think it's the success response. I assumed it might be because the order is invalid so tried to list new items to get valid orders but the uploading image feature in sandbox is so broken somehow (you can see the tickets related to it) and couldn't get through it. what do I need to get it right?
Can you provide **any test order data** which is valid for success and failure cases for this cancellation API if it's possible? Thank you for your help in advance
