I will fix n8n workflow API and webhook errors
Zahurul Islam
About this gig
Is your n8n workflow failing, duplicating records, missing webhook events, or breaking on an API call?
I diagnose and fix n8n automation problems instead of blindly rebuilding the whole workflow.
I can troubleshoot:
Failed executions and node errors
REST API and HTTP Request issues
Webhook triggers and payload problems
OAuth, tokens, and authentication flow
Data mapping and expression errors
Duplicate records and repeated events
Retry and error-handling logic
Conditional routing and branching
Broken app integrations
Slow or fragile workflows
AI workflow output and structured-data issues
My integration work includes production ecommerce and Zoho workflows where missing or duplicated records are not acceptable.
Send me the workflow, failed execution, error message, and expected result before ordering. I will confirm whether the issue fits the selected package.

FAQ
Can you fix a workflow you did not build?
Yes. I can inspect an existing n8n workflow and diagnose the current logic before changing it.
What should I send before ordering?
Please send the workflow JSON or screenshots, the failed execution details, the error message, and the expected result.
Can you fix API authentication issues?
Yes, when the issue is within the available API documentation, credentials, permissions, and n8n setup.
Can you fix webhook problems?
Yes. I can inspect webhook configuration, request payloads, response behavior, routing, and downstream workflow logic.
Do you support self-hosted n8n?
Yes, for workflow-level troubleshooting. Server, Docker, networking, or infrastructure issues should be confirmed before ordering because they can require a separate scope.
Can you fix AI agent workflows?
Yes, when the issue involves n8n workflow logic, API calls, structured outputs, routing, tool calls, or integration behavior. Deep model training is not part of this Gig.
