Found an issue this morning where the Authorization process was not working. The dealer was sent to a normal eBay login instead of the third party authorization login. This would result in the client logging in and landing on the eBay home page with no authorization occurring. The issue is in the URL.
We were using https://signin.ebay.com/saw-cgi/eBayISAPI.dllfor the last 16 years.
But as of today you need to use.
https://signin.ebay.com/ws/eBayISAPI.dll.
Your welcome.
