I will debug failed n8n workflows, fix execution errors and troubleshoot API issues


About this gig
Is your n8n workflow failing, stopping at a node, or returning API errors? I diagnose the cause and repair existing automations so your business process can run as intended.
I help founders, operations teams, and agencies who rely on an active workflow and need to unblock lead routing, data transfer, notifications, or AI steps without rebuilding everything from scratch.
I inspect execution logs, node inputs and outputs, expressions, credentials, HTTP responses, webhook payloads, and data mappings. Depending on the agreed scope, I fix the faulty node or request, correct data handling, add practical error handling, and retest the affected path.
You receive the repaired workflow, a concise root cause summary, test notes, and practical steps to reduce repeat failures. I work from a safe export or copy where possible and never change a live system without approval. Third party outages, expired credentials, API limits, and inaccessible services may need your action.
Send a redacted workflow export, the exact error message, what should happen, what happens instead, and your deadline. I'll confirm feasibility and scope before you order.

FAQ
What do you need to diagnose my n8n workflow?
Please provide a redacted workflow export, the execution error or relevant log, the expected result, and the observed failure.
Can you repair API and webhook errors?
Yes, when the issue is reproducible and the required documentation, configuration details and access are available. Third-party outages or permissions may require your action.
Will you rebuild my entire workflow?
Not by default. I focus on diagnosing and repairing the affected path. Rebuilding or adding unrelated features requires a separate scope.
Do you include testing after the fix?
Yes. The agreed repair includes retesting the affected path and a concise explanation of the result. Broader regression testing belongs in a larger package.
Do you provide ongoing monitoring or paid service subscriptions?
No, not by default. Hosting, paid applications, API usage and ongoing monitoring are separate unless explicitly included in the agreed scope.
