How I build an automation workflow

A job that used to be somebody’s morning now runs on a trigger, validates its own input, and reports when it fails.

A walkthrough of the build itself, not a single engagement. Client names and numbers go up here as clients sign off on them.

Service: Automation workflow build
What it covers: Triggers, validation, routing, retries
Runs on: n8n

The system that got built

Webhook

Called by the upstream system

Scheduled run

Fires on its own interval

New GoHighLevel contact

Triggers on contact create

Validate and enrich

Bad input stops here, loudly

Retry on failure

Backoff, then hand it to a human

Route by condition

One branch per case

GoHighLevel

Contact, tag, or pipeline update

Google Sheets

Appends the run’s row

Slack alert

Only when a human is needed

The problem

Someone opens a laptop every morning and moves the same data between the same three tools. It takes an hour, it gets skipped whenever they are away, and when it goes wrong nobody finds out until a customer does.

What I built

An n8n workflow with one branch per real case
A webhook, a schedule, or a new contact as the entry point
Input validation that fails loudly, not silently
Enrichment before anything downstream runs
Conditional routing, so each case does only what it needs
Retry with backoff, then a Slack alert to a human
Writes back to GoHighLevel, Sheets, and Slack
Run logging, so a failed run can be traced

How it’s wired

Trigger

The run starts from a webhook, a schedule, or a new contact rather than from someone remembering. That is the whole point of the build.
Validate

Input is checked before anything downstream runs, so bad data fails in one place instead of corrupting three systems.
Route

Conditions split the run into one branch per case, each doing only what that case needs.
Recover

Failures loop back through validation with backoff; if they still fail, a Slack alert names the run so a human can pick it up. Silent failure is the thing being designed out.

What you get

The workflow lives in your own n8n, not rented from me
Every run logged, and every failure named
A retry path that runs before a human is involved
