API Integration for Email Verification

I need help integrating the backend API with the frontend for email authentication verification in my mobile app.

Requirements:

- Configure API routing in the necessary frontend files

Core Technologies:

- Android Java
- MongoDB

Ideal Skills and Experience:
- Proficiency in Node.js and Android Java

The email verification request will be triggered during user registration. You will be working with a ready-to-use API endpoint and using Nodemailer with Gmail SMTP as the email service provider.
