I will integrate apis into your app, website or software


About this gig
Need to connect an API to your app, website, or software?
I can integrate third-party APIs, REST APIs, webhooks, authentication, and external services into your existing application.
I can help with:
- REST API integration
- Third-party API integration
- Webhooks and API authentication
- OpenAI and AI API integrations
- Telegram and WhatsApp integrations
- Backend and database integrations
- Connecting external services to existing applications
- Fixing or completing existing API integrations
I work with Node.js, Express.js, JavaScript, PostgreSQL, and other API-based services.
I have hands-on experience building full-stack products with multiple external integrations, so I understand both the API side and how it needs to work within the complete application.
Please contact me before ordering if your integration is complex or you are unsure which package fits your project. I can review your requirements and recommend the right scope.

FAQ
What do you need from me to start?
Please provide the API documentation, details about your existing application, the functionality you want to integrate, and any required API credentials or test access.
What is included in the Basic package?
The Basic package is intended for one simple API endpoint in an existing application. Authentication, multiple endpoints, webhooks, database work, or more complex logic may require a Standard or Premium package.
Can you integrate an API that is not listed in your Gig?
Yes. I can work with many REST APIs and third-party services. Send me the API documentation and your requirements before ordering, and I will confirm whether I can integrate it.
Can you work with an existing project or codebase?
Yes. I can integrate APIs into existing applications and also troubleshoot, fix, or complete existing integrations. Please contact me first if the codebase or integration is complex.
