Auth Plugin requirements

Description and requirements of a user authentication plugin.

You need a plugin if your application uses another authentication service, not supported by the Platform authorization methods.

We can make a plugin for any authentication service compatible with the following flow:

This is a piece of the full Flow diagram:

pageVPN Platform Flow

oAuth Server - your User authentication service.

App - your application with our SDK

1st phase (Authorization): A user authentication to the oAuth Server. The App gets an oAuth token (Steps 1-3 in the Flow diagram).

2nd phase (Login to Platform):

Step 4: The App calls a POST /user/login method (or calls a login method of our SDK) with the parameter "auth_method" = your plugin name and "access_token" = oAuth token.

Step 5: The Platform verifies this oAuth token in your oAuth Server. In this step, the "GetUserInfo (oauth_token)" method is called (its name can be changed). You should provide this method for us.

Step 6: The example of the response to this method:

{ 
  "result": "OK", 
  "user": 
    { 
      "uid": 690109944 
    } 
}

or

{ 
  "result": "Not found" 
}

If a user's oAuth token verification is successful, the response includes {"result": "OK"} and additional user information (e.g., UID on your side). If a user's oAuth token verification is unsuccessful, the response is {"result": "Not found"} or any similar response.

Step 7: If the verification is unsuccessful, the Platform returns an error code:

{
  "result": "OAUTH_ERROR",
  "error": "failed login"
}

If the verification is successful, the Platform registers the user and his device in the project. The process of registration can include set specific user parameters like Traffic, License, Status, Extref, Description, User country (it depends on your application logic). See descriptions of these parameters:
