You will get your Broken N8n Workflows & API Fixed > Today?
Project details
Is your n8n workflow "Failing"? Don't panic.
Nothing is more frustrating than an automation that worked yesterday but is throwing a red error today. Whether it’s a Credential Error, a JSON mapping issue, or a Rate-limit headache, I specialize in the "weird" problems that stop you development.
1. The Silent Killer Fix: I find why your workflow says "Success" but the data never actually reaches your CRM or Sheet.
2. API Handshaking: I fix broken OAuth2, Header issues, and "401 Unauthorized" errors that keep you locked out of your tools.
3. Data Rescue: If your data is coming in messy or nested too deep (like tha amazingt AI output youve got), I'll write the Javascript code to flatten it and make it usable.
4. Proxy & Scraper Repairs: Getting blocked? I'll integrate your SOCKS5 proxies and fix your "Wait" logic so your scrapers stay under the radar.
I offer a no fix no fee policy.
Before pruchase this service please drop me a message so we have a quick chat about your requiremnt.

Expert Automation Engineer: n8n Lead Engine Optimization (Apollo + GoHighLevel)
Francesco was fantastic to work with. What he promised he delivered. He has deep technical expertise and the solution he built for us was exactly what we asked for.
I especially appreciated the extra time he took to help us with the setup which was outside of the scope of our original agreement. He also gave us all of the relevant documentation for the solution so we will be able to make changes going forward if we require. Thank you Francesco!

About Francesco
n8n Automation Engineer, AI Agent Builder, Apollo GHL CRM Pipes
London, United Kingdom - 1:08 pm local time
Every new client takes 2-3 hours of manual setup and tag fixes. VAs are scrubbing leads by hand, breaking workflows, and introducing errors that burn your sending domains. Bad data flows into CRM unchecked and corrupts automations you spent weeks building.
I fix the layer underneath the data infrastructure between your outbound tools and CRM that nobody built properly the first time.
Every engagement I deliver:
Cleans and standardises your lead data to a consistent schema before it touches your CRM
Maps industries to your specific verticals so contacts are tagged correctly from day one
Verifies emails at the gate undeliverable addresses never reach GHL
Automates the setup logic that your VAs are currently doing manually
Builds modular n8n workflows with error handling and logging so nothing fails silently
The result is a GHL operation that scales without adding headcount. New sub-accounts deploy cleanly. Leads arrive verified and tagged. Your team stops firefighting and starts closing.
I've built this in production a live pipeline processing thousands of leads per week with zero manual intervention, full audit trail, and automatic failure recovery.
If your agency is managing multiple sub-accounts and you're still relying on VAs to keep your CRM clean that's the problem I solve.
