Is your n8n workflow failing because of a webhook, REST API, authentication, JSON mapping, duplicate event, retry, or rate-limit problem? I will diagnose the reported failure, repair the agreed workflow path, test it with buyer-approved sample data, and document the changes. I am Fiverr Pro-vetted for Support & IT with hands-on experience building n8n workflows and troubleshooting APIs, webhooks, authentication, mappings, retries, and rate limits. Deliverables may include: - failure diagnosis and an agreed repair - corrected export or approved instance changes - buyer-approved test evidence - change log and remaining limitations - reliability improvements where included Contact me before ordering if the workflow uses custom code, AI agents, community nodes, multiple integrations, or a production-critical system. These packages repair existing workflows. New builds, infrastructure, third-party outages, major JavaScript rewrites, prompt/RAG work, and vector databases require separate scoping. Never send passwords, tokens, API keys, private keys, or sensitive payloads through Fiverr messages or exports. Live changes require buyer approval and temporary least-privilege access.

FAQ
Can you guarantee that every workflow will be repaired?
No. I first confirm whether the reported issue appears reproducible and feasible. Third-party outages, unavailable APIs, undocumented restrictions, and platform limitations cannot be guaranteed.
What access do you need?
We begin with a sanitized workflow export, redacted logs, and sample data. Temporary least-privilege access is requested only when implementation or live validation requires it.
Do you support n8n Cloud and self-hosted n8n?
Yes, at the workflow layer. Server, Docker, database, networking, proxy, SSL, and upgrade work are not included unless separately scoped.
Do you build new workflows?
These packages repair existing workflows. Minor changes needed for the agreed fix are included; new workflows or substantial new business logic require a custom offer.
How are credentials handled?
Never send raw passwords, tokens, API keys, or private keys in Fiverr messages or exports. Install temporary credentials in your own n8n credential store and revoke access after delivery.
Do you troubleshoot AI workflows?
Yes, when the issue involves orchestration, APIs, webhooks, mappings, authentication, or error handling. Prompt redesign, model quality, RAG, and vector databases require separate scope.
