In this tutorial, i will show you how to create rest api in laravel 5.8 application with passport authentication. In this tutorial we will be using passport for api authentication. we will create register and login api with simple retrieve user details.

Laravel comes with default login authentication, but when we want to create APIs we have to use tokens instead of sessions for authenticating users, as APIs does not support session variables. After login via API, user must be assigned a token and sent back to the user which is further used for authenticating API requests. Laravel provides Passport authentication which makes it easy creating REST APIs in laravel.

Testing the REST API

Our Authentication API is ready to test. I will use Postman to test the API.

Register Api :-
Verb: POST
URL :http://localhost:8000/Api/v1/register

Login Api :-
Verb: GET
URL :http://localhost:8000/Api/v1/login

getUser Api :-
Verb: GET
URL: http://localhost:8000/Api/v1/getUser

When testing getUser API it requires user to be authenticated, you need to specify headers. Make sure in getUser api we will use following headers as listed bellow.

Basically, you have to specify access token as a Bearer token in the Authorization header. The access token is what you received after login and registration.
