You can add keys using a post to a non existent key ID like this:
These aren't OAuth tokens obviously, you are just registering a key with Tyk and some access rules + expiry, Tyk will then evaluate that key on inbound requests.
One caveat is that the standard OAuth Authorization header might not work because of the Bearer component of the field value, if you exclude that keyword and just add the key to the auth header it should work fine.
Naturally, with flow 1. You don't get refresh tokens or any of that jazz as that's been delegated to another provider.
hope that helps
