I am new to eBay APIs, I understand the API, but I am just stuck on the OAuth2.0 authorisation. I have an application that I am making for my ebay store, no one else will use the application except me. Will I have to sign in everytime I run the application? I am also struggling to get OAuth to work in my application in terms of generating a token etc. Any help would be great, as I said I'm a newbie to the eBay APIs, so I'm pretty sure this is an easy question, with an easy answer for everyone else haha.
