I want create api for mobile app so how can i create api for android mobile app. I want a login url for login using username and password.

You need to use JWT Auth API for login user and then use api generator for generate your apis adding

->middleware('\Tymon\JWTAuth\Middleware\GetUserFromToken');

to {root}\plugins\ahmadfatoni\apigenerator\routes.php

so you can integrate jwtauth to your api
