Integration with Bulk Sell failing

[oldtimecruiser]

I took over a project that has an integration with file exchange, which uses this endpoint: 

https://bulksell.ebay.com/ws/eBayISAPI.dll?FileExchangeUpload

That endpoint now redirects to an error page.  I'm looking for a migration guide for this endpoint, or really any information on it and what's become of it.

File Exchange has moved into Seller Hub, where a spreadsheet can be manually uploaded for listing in bulk.

https://www.ebay.com/sh/resources/reports 

The File Exchange column headings are currently acceptable in Seller Hub, which has exploded the words in headings for better readability.

To use a programmatic method, eBay now requires token setting to access a feed API. It will not be a simple switch to a new endpoint.

Here are links to the Seller Hub fx-feeds page, and related pages:

https://developer.ebay.com/api-docs/sell/static/feed/fx-feeds-references.htmlhttps://developer.ebay.com/api-docs/sell/static/feed/general-feed-tasks.html

In order to use the new feed endpoint with OAuth, you will need to sign up for a developer account.

Currently, many new signups are being rejected, and I don't know why.

The developer forums have recently been moved here:

https://community.ebay.com/t5/Developer-Forums/ct-p/developergroup

And, unfortunately, the wealth of historical forum help has been lost. 😞

Below are my conversion notes from two years ago, although I have not attempted anything and don't know how to use the methods described. eBay recently purged or lost many of the developer support pages, so there may be some dead links (sorry about that) but I wanted to lay out the notes as they were given.

Please use scope https://api.ebay.com/oauth/api_scope/sell.inventory while generating a user access token to execute the createTask call for FX_LISTING feedType.

OAuth endpoint at
https://api.ebay.com/identity/v1/oauth2/token

feedType = FX_LISTING (for creating, revising, ending listings)
POST event

The taskId generated in the Feed API is alphanumeric format (task-xx-xxxxxx).

A schemaVersion parameter is required for the createTask method.
This parameter sets the version number of the API schema that you are programming against.
For File Exchange feed types, the value of schemaVersion should always be set to "1.0".
