I will fix API errors, webhooks, and integration issues
Lee Adams
About this gig
Having trouble with an API, webhook, or integration that just won't work properly?
I can help debug and fix issues with APIs, webhooks, backend connections, authentication, JSON data, failed requests, broken responses, payment/status updates, and more.
I'm Lee, a UK-based developer with 6+ years of programming experience. I work with JavaScript, Node.js, TypeScript, Python, PHP, and modern backend frameworks, and I'm comfortable jumping into existing codebases to find what's going wrong.
I can help with:
- API errors and failed requests
- Webhook setup or debugging
- REST API integrations
- Authentication/API key issues
- Frontend-to-backend connection problems
- JSON/data formatting issues
- Database-backed integration bugs
- Stripe/payment/order status webhook issues
Why work with me?
- Clear, friendly communication
- Clean and maintainable fixes
- Fast delivery without rushed work
- I'll explain what I changed in plain English
Please message me before ordering so I can check the issue and recommend the right package.

FAQ
Should I message you before ordering?
Yes, please. API and webhook issues can vary a lot. Send me the problem, any error messages, what should happen, and your tech stack. I’ll check the scope and recommend the right package before you order.
What counts as a small API or webhook fix?
A small fix is one clear issue, such as a failed request, broken webhook handler, auth/API key problem, bad endpoint, JSON issue, or frontend-to-backend connection bug. Larger flows may need a bigger package.
Can you work with my existing codebase?
Yes. I can work with existing projects if the code and setup details are available. I mainly work with JavaScript, Node.js, TypeScript, Python, and PHP. If your stack is different, message me first.
What access will you need?
It depends on the issue. I may need code access, API docs, logs, test credentials, webhook settings, environment details, or a staging site. Please avoid sending production secrets unless needed and rotate them afterwards.
Will you test the fix before delivery?
Yes. I’ll test the fix as much as your access allows, including API responses, webhook payloads, logs, or the affected user flow. If full testing needs third-party access, I’ll explain what I verified.
Do you build full API integrations from scratch?
This gig is mainly for fixing and improving existing API, webhook, and integration issues. I can build small integrations or endpoints too, but please message me first for larger custom work.
