Fix webhook issues in your website or backend
- Views 12
What you get with this Offer
I can help debug and fix one clear webhook issue in your website, app, or backend. This could be a failed webhook event, bad payload handling, missing signature validation, authentication issue, incorrect response, broken endpoint, duplicate event handling, or a backend status update that is not working properly.
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 webhook logs, payloads, backend code, API responses, and third-party documentation to find what is actually going wrong.
What I can help with:
- Webhooks not firing
- Failed webhook requests
- JSON payload issues
- Signature or token validation problems
- Authentication/API key issues
- Backend webhook handler bugs
- Duplicate event handling
- Payment/order/status webhook issues
- Webhook response or error debugging
What is included:
- Investigation of one clear webhook 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 webhook issue and confirm it fits this offer. If the task involves multiple systems, a full integration rebuild, complex payment flows, or database-heavy changes, 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 webhook issue
- What is currently happening
- What should happen instead
- The webhook provider or service involved, if you know it
- Any webhook logs, error messages, failed requests, or screenshots
- Example payloads or event data, if available
- The endpoint URL/route involved, if relevant
- Any API/webhook 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, sandbox details, or webhook dashboard access 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, webhook secrets or credentials are required, test credentials or temporary access are best where possible.
