Hello Everyone, we have programmed an .NET-ASP-Interface for the Software of a Customer, which is using the Ebay .NET SDK and communicates to the Trading API. Working fine since couple of months and nothing of the Code in this WebApplication has changed since the Beginning of the Interface. Some days ago the Authentication-Token began to be only valid for a short time. API suddenly says "Verification of the authentication token in the API request was unsuccessful". I create a new Token and everything is working fine. After a short time, the API says again that the Auhtentication Token is not valid. Can Anyone help me please ?!
Hi @gregormannek, Thanks for your post. Can you please send us the request and response files? We would like to check the logs from our end. Also, can you please send us the ebay UserID or seller ID? Please remove the token and send it accordingly. Best Regards, eBay Developer Support
Hi, Thanks for your reply. I checked your Seller ID: and found that the only App which has valid token is 235958(AppID). Can you please let us know if you are able to make calls from this AppID? Also, please specify the AppID that you are using to make calls. Best Regards, eBay Developer Support
