Hi,

I have developed a very solid REST API based platform using C# in VS2022. I am basically taking Excel product data and publishing a listing using the required steps. All good. The ImageUrls I loaded in the JSON payload were all hosting on my own domain, around 15 per item.

Oddly; I was about to copy and paste the warning that appeared at the top of the listing; the warning included a link to a page that reads:

It appears you are using images from a self-hosted or 3rd party image provider.

There was a problem uploading your self-hosted image to Ebay, please resubmit your self-hosted images via your 3rd Party Tool or API solution, or contact Customer Support for further help.

BUT now (about 1/2 hour later) the listing appears fine, I cannot see any errors or warnings. Anyone have any insight ?

I do not want to use the legacy API as I have no code set up to manage this, all Tokens are REST based. All Google searches point to UploadSiteHostedPictures on legacy API pages, nothing at-all on the RESTful approach.

Curious indeed.

Do you have a live item number to review. Generally, valid images fail to transload to eBay servers due to the third-party server being too slow to respond to eBay image requests. Typically, a few images make it, and then the remainder fail when eBay overloads the remote server with image requests. Once the images fail to transload, eBay will deliver your third-party URLs to the listing, rather than creating eBay URLs. I don't know if this is your situation, but the solution is to reduce the file size of the images and/or reduce the number of images in the request.

Thanks, this makes sense. I have ensured images are no more than 1200x960 and there shouldn't be too much latency on the server. Links to all images in the listing looked OK before I deleted it. Still some functionality away from my first upload run. Appreciate your insight into the process.
