About this gig
Need a REST API or webhook connected to your Node.js application?
I build focused third-party API integrations using Node.js, Express.js, JavaScript, REST APIs, and PostgreSQL.
WHAT I CAN DO:
- Connect documented third-party REST API endpoints
- Handle API key or token-based requests
- Map JSON responses to your existing application
- Add basic request validation and error handling
- Receive and process a defined webhook event
- Test requests, responses, and the agreed data flow
PACKAGES:
Basic: 1 simple API endpoint connection.
Standard: 1 API data flow with mapping and testing.
Premium: 1 scoped inbound webhook event flow.
YOU WILL RECEIVE:
- Agreed source-code changes
- Tests of the affected integration
- Brief setup and handover notes
Please message me BEFORE ordering with your API documentation, current tech stack, and expected workflow.
Packages cover an existing Node.js/Express app and documented APIs. OAuth setup, payment processing, complex retries, multi-system sync, hosting, and paid API fees require a custom offer. Never send live API keys in chat.

FAQ
What types of APIs can you integrate?
I work with documented REST APIs and webhooks in existing Node.js/Express applications. I can handle JSON data, API requests, basic authentication, data mapping, and defined event processing.
Can you build webhook integrations?
Yes. The Premium package covers one clearly defined inbound webhook event. Complex retries, multiple event types, payment processing, or advanced synchronization require a custom quote.
What is the difference between your packages?
Basic connects one simple API endpoint. Standard implements one defined API data flow. Premium handles one inbound webhook event flow. Please message me to confirm which package fits your requirements.
What do you need before starting?
Please provide the API documentation, current backend framework, expected behavior, and relevant endpoint details. I will review the requirements and arrange secure test access if needed.
Do you provide testing and documentation?
Yes. I test the agreed API or webhook flow and provide a brief summary of the implementation, including configuration details relevant to the delivered integration.
Can you integrate payment gateways or OAuth?
These may be possible depending on your project, but they are not included in the standard packages. Please contact me first for a custom scope and quote.
