When create an APP in Pluggto you will register a URL that all users will be redirect when they click your application.
In the URL we will gonna send a parameter called "pluggtocode" that you should access an send to our API with your "client_id" and "client_secreat", passing it as the parameter "code". This code is valid only for the first called, or few minutes, and will give as return the user access_token and refresh_token that you should keep in your database.
To get a access_token from plugin authetication method you need 4 credencials.
- client_id - Plugin API id
