About this gig

I will integrate reliable REST APIs, payment gateways, webhooks, authentication systems, and third-party services into your web application.

I can help you connect your frontend or backend with external services and ensure the integration is secure, stable, and properly tested.

I can help with:

  • REST API integration
  • Payment gateway integration
  • Third-party API integration
  • Webhooks and callback handling
  • OAuth and API authentication
  • Frontend-to-backend API connections
  • API debugging and error handling
  • JSON data handling
  • Existing API integration fixes
  • Node.js, React, TypeScript, and JavaScript applications

Whether you need a simple API connected to your website or a more advanced payment, authentication, or webhook workflow, I can implement it cleanly and efficiently.

For complex integrations or multiple services, please message me before ordering so I can review the requirements and recommend the right package.

Why work with me?

I focus on clean code, secure integrations, clear communication, and solutions that work reliably in production.

Please contact me before placing an order for payment gateways or complex third-party integrations.
