What you get with this Offer
I can help debug and fix one clear API request or response issue in your website, app, or backend. This could be a failed request, 400/401/403/404/500 error, bad JSON response, missing header, authentication issue, incorrect endpoint, timeout, or frontend-to-backend API problem.
I'm Lee, a UK-based developer with 6+ years of programming experience. I work with technologies such as JavaScript, Node.js, TypeScript, Python, PHP, FastAPI, Laravel, and more. I'm comfortable checking request data, response bodies, logs, headers, API documentation, and backend code to find what is actually causing the issue.
What I can help with:
- Failed API requests
- 400, 401, 403, 404, or 500 errors
- Bad or unexpected API responses
- JSON request/response issues
- Missing headers or incorrect request data
- Authentication or API key problems
- Frontend-to-backend API bugs
- Endpoint, route, or payload debugging
- API error logs and response troubleshooting
What is included:
- Investigation of one clear API request/response issue
- A clean fix where the issue is within the agreed scope
- Testing where your access/setup allows
- A clear explanation of what was changed
- Friendly communication throughout
Please message me before ordering so I can check the API issue and confirm it fits this offer. If the task involves multiple APIs, a full integration rebuild, complex backend changes, or several unrelated errors, I can still help but we may need to agree a custom scope first.
What the Freelancer needs to start the work
To get started, please send as much of the following as you can:
- A short description of the API request or response issue
- What is currently happening
- What should happen instead
- The API provider/service involved, if there is one
- Any error messages, logs, status codes, or screenshots
- Example request data, headers, payloads, or response bodies, if available
- The affected endpoint URL/route, if relevant
- Any API documentation from the third-party service
- The technology/framework used, if you know it
- Access to the code, repository, staging site, or backend files needed to investigate
- Any test credentials, API keys, or sandbox details needed for testing
If you are not sure about some of this, that is completely fine. Just send what you have and I’ll guide you from there.
Please avoid sharing sensitive production secrets unless they are genuinely needed. If API keys, tokens, or credentials are required, test credentials or temporary access are best where possible.
