When we talk about OAuth, it's the process in which you're generating the token. There are four main ways. First is merchant generated (Merchant Web Dashboard > Settings > API Tokens). This is purely for testing and limited access to APIs.
Second is `Token` from OAuth Request. This is also limited to testing.
Third is the `Code` you see in the radio selection in the image above. That's the one you'll need to use in order to generate a proper OAuth token for all access to our APIs. Fourth is the
Android generated token, which should have all access as well.
If you're having issues with generated `Code` OAuth, please take a look at this video: https://www.youtube.com/watch?v=6riNP_wlKcU
