We have an ebay dev account and through ebay application, the token works fine (when we click on the user token/oauth application token).
As we are working on the ebay integration, we tried to generate a token during our development as mentioned in the ebay developer documentation. But it fails for no reason. Without authentication we are not able to proceed further. Tried using postman but same error.
As a work around also tried copying the user token from the ebay application and inserted that in the place of authorization in psotman but nothing works.
