I'm lost and i need help. The API documentation is just.... I don't know where to start. Why are there not any simple tutorials? I have managed to generate an access token using the Oauth flow. - all good. I am then using postman to test the api: GET:
https://api.ebay.com/sell/inventory/v1/inventory_item Authorization; Bearer Result is a 403 forbidden - that's it nothing more! What is the secret? Why so painful? Please document the process in the docs correctly instead of leading us in a loop of illogical poorly written mess.
Yes I have already read and followed the guides as per your links. But it i not possible to make the request for the user token programmatically. It only works if you make the request from the developer program control panel to manually get the token and paste into whichever application is making the requests. This unfortunately renders the API useless - I already have given up on the idea of being able to use it for anything meaningful.
