I will integrate third party apis into your nodejs backend


About this gig
Need to connect a third-party API to your Node.js backend? I will build a clean, reliable integration using JavaScript or TypeScript and test the complete data flow.
I am a UK-based backend developer experienced with Node.js, REST APIs, authentication, webhooks, databases and production environments.
I can help with:
- REST API integrations
- API keys, OAuth and token authentication
- Webhooks and callback handlers
- Data mapping, validation and transformation
- Database reads and writes
- Error handling, retries and logging
- Express, NestJS, Fastify and other Node.js frameworks
You will receive:
- A maintainable integration in your existing codebase
- Testing of the agreed endpoints or workflow
- Clear error handling
- A summary of what was added
Please message me before ordering with the API documentation, your technology stack, the actions or data you need, and the desired workflow. I will confirm the scope and recommend the right package.
This Gig covers new integrations with documented third-party APIs. Full application development, major infrastructure changes and repairs to existing integrations may require a separate Gig or custom offer.

FAQ
Should I contact you before placing an order?
Yes, please message me first with the API documentation, your current technology stack, and a brief description of the workflow you need. I will review the scope and recommend the appropriate package or a custom offer.
Can you integrate any third-party API?
I can work with most documented REST APIs that are accessible to your project. Please send the documentation before ordering so I can confirm the authentication method, endpoints, limitations and expected complexity.
What counts as one API endpoint or action?
One endpoint or action is one clearly defined operation, such as retrieving a customer, creating an order, sending a message or updating a record. Several requests that form one larger workflow may require the Standard or Premium package.
What access and information will you need?
I may need access to the relevant source code, setup instructions, API documentation, a test or sandbox account, and the required environment variables. Please do not send personal passwords or production secrets. Temporary, restricted or test credentials are preferred.
Do you support authentication, webhooks and databases?
Yes. I can work with API keys, bearer tokens, OAuth, webhooks and database-connected integrations. The required package or extras will depend on the number of actions and the complexity of the workflow.
What does a revision include?
A revision covers adjustments needed for the agreed integration to meet the original requirements. New endpoints, changed workflows, different API providers or additional features are outside the original scope and may require an extra or custom offer.
