Hi Malcolm and Neon Man,
I’m currently facing the same issue when trying to publish offers on eBay using the Inventory API.
The error messages are related to the Return policy (ReturnsAcceptedOption, ReturnsWithinOption, ShippingCostPaidByOption) and Fulfillment policy, just like what you shared above.
I’ve tried adding a delay (even 3–5 seconds) between the inventory item, offer creation, and publish steps — but the error still persists.
Were you able to resolve this issue in the end?
If so, could you please share what worked for you?
Really appreciate any help!
Thanks 🙏
