About this gig

Need to connect your React, Nextjs, JavaScript, or TypeScript application to an external API?


I can integrate third-party APIs into existing web applications and handle the frontend and backend logic needed to make the connection work reliably.


I can help with:


  • REST API integration
  • React and Nextjs API connections
  • JavaScript and TypeScript integrations
  • Node.js backend integration
  • API authentication and authorization
  • Multiple API endpoints
  • Webhooks and event handling
  • Data fetching and processing
  • Error handling and validation
  • Forms and API submissions
  • External services and platforms
  • Troubleshooting existing API integrations


I focus on clean implementation, reliable data handling, proper error handling, and integrating the API without unnecessary changes to your existing application.


Please contact me before ordering if your integration requires OAuth, webhooks, payments, multiple services, or complex backend logic so I can review the API documentation and recommend the correct package or custom offer.
