Developing an original API function with doorkeeper and oauth2.

I have had an opportunity to develop an API login function between two web services. The way to do that is a little complex and demanding, so I’ve decided to take a not about necessary knowledge.

This is a gem by which you can develop an API feature easily. Moreover, I used this gem for oauth.

That’s all.

With these gems, user can be given a permission, which means an access token, from an authorization server. This system is defined as RFC6749. The details is here.

You can make an API feature with the knowledge above. I hope that this information would be a help to you.
