Zavier
About this gig
Need a custom REST API or a reliable connection between your applications?
I can develop and integrate REST APIs using Node.js and help connect your website, web application, mobile app, or third party service with the backend it needs.
My service can include:
- Custom REST API development
- API integration with third-party services
- Node.js backend development
- API endpoints and JSON responses
- Authentication and authorization
- Webhook integration
- Database integration
- API testing with Postman
- API documentation with Swagger
- Connecting existing applications to APIs
I focus on building clean, practical integrations that are easy to test and maintain. If you already have an API that isn't working correctly, I can also review the existing setup and identify what needs to be changed.
Before placing an order, please send me your requirements, API documentation, or a short explanation of what you want to connect. This helps me confirm the scope and choose the right package for your project.

I help businesses connect their apps and services through reliable API integrations. I can build, connect, test, and troubleshoot REST APIs, webhooks, third-party APIs, and custom integrations. Whether your API is failing, two platforms aren't communicating, or you need a new integration, I'll work to find the cause and deliver a clean, practical solution that works.
FAQ
What type of API can you develop?
I can develop custom REST APIs and backend endpoints using Node.js, including JSON-based requests and responses.
Can you integrate a third party API with my website or application?
Yes. I can connect supported third-party APIs to your website, web application, or backend and handle the required requests, responses, and authentication.
Can you connect the API to a database?
Yes. Database integration is available in the Standard and Premium packages. Please contact me first if your project has complex database requirements.
Can you fix an existing API instead of building a new one?
Yes. I can review an existing REST API or Node.js backend and troubleshoot integration, endpoint, authentication, or response-related issues.
What do you need before starting?
Please provide your project requirements, API documentation, existing code or repository when applicable, access to a test environment, and any relevant credentials or configuration details. Never send unnecessary production secrets.
