Build API for Payment Gateway Integration in Node.js
Skills Required
Description
Developing a secure and efficient API for payment gateway integration is crucial to ensure smooth and reliable transactions. This project focuses on building an API in Node.js that connects seamlessly with payment gateways, processes transactions, and returns accurate, real-time responses to the client application.
The work will involve setting up a robust backend using Express.js and ensuring all routes are secure. The developer will also handle request validation, error handling, and transaction logging for transparency and troubleshooting.
Integration will cover multiple payment methods, including credit/debit cards and other online payment services, ensuring flexibility for end-users. Security standards such as HTTPS, token-based authentication, and PCI DSS compliance will be followed to protect sensitive payment data.
Database integration using MongoDB will store transaction histories, payment statuses, and user payment preferences. Queries will be optimized for performance to handle high transaction volumes without delays.
Testing will be performed extensively using Postman and automated scripts to ensure every API endpoint works correctly under various scenarios. Mock transactions will be conducted to validate responses and error messages.
The API will be documented clearly, making it easy for frontend developers or other third-party services to integrate with minimal friction. This will include endpoint details, parameters,...
