Full error name: “At least one valid postage service must be specified. ErrorCode: 21915469“
May 3, 2023
eBay returns this error if your listings miss a valid postage service.
Please update the Shipping policy or edit it:
- Open your Policy manager (eBay Business Policies direct link and click on “opt in”)
- Look for the policy you’ve picked on Nembol and update it by clicking on edit, and then on save (in this way you will update the postage info)
- Once done, make sure to select this same policy in your “List to eBay” settings on Nembol – See the screenshot below.
- Remember to save.
If that doesn’t work, please consider editing or creating an additional Shipping policy (even similar) to associate with Nembol.
