Hello! I am a Laravel developer specializing in debugging and fixing API and authentication problems.

If your frontend, mobile app or Postman requests are not connecting to your Laravel backend I can help.

I can fix:

Laravel API not responding

401 Unauthorized / 419 Page Expired

Sanctum authentication not working

Passport token issues

Token mismatch error

Login / Register not working

CORS errors

Session & cookie problems

Mobile app API connection (React, Vue, Flutter, Android, iOS)

Postman API errors

Middleware & guard configuration issues

Common reasons these happen:

misconfigured .env file, wrong APP_URL, session driver, CSRF protection, incorrect guards, HTTPS/cookie settings or server configuration.

What you will get:

Proper debugging and root-cause fix

Clean and stable authentication flow

Guidance on how to avoid the issue again

I support:

Laravel 6 / 7 / 8 / 9 / 10 / 11

Sanctum Passport REST API JSON API

Please send:

Website URL, error screenshot, and what action causes the error.

I respond quickly and will first analyze the issue before asking you to place an order.
