n8n automation, built by engineers and handed over working

1. An AI music radio that produces its own shows

Two workflows. The first runs on a schedule: it gathers the latest music news, has GPT-4 write a script, renders the voice with ElevenLabs, mixes background music under it with FFmpeg, saves the record to Google Sheets and sends the segment to the radio platform through its API. The second manages the video library: it walks artists in sequence, fetches their videos, keeps only those in a set length window, picks one that has not played yet, updates the playlist and calls the next part of the workflow.

1. Select next artist
2. Fetch all videos
3. Keep eligible lengths
4. Pick an unseen video
5. Edit fields
6. Call part 2

The detail that makes it work unattended is the "unseen" filter: without it, a random pick can play the same video again.

2. Browser order automation for WooCommerce

The main order process runs through browser automation rather than by hand. The workflow pulls new WooCommerce orders on a schedule, removes duplicates, then loops through them one at a time with a wait between each, writes the customer details to a file the browser automation reads, runs it, parses the result and marks the order in WooCommerce only if it was really created.

Removing duplicates before the loop, not after, is what stops one order being placed twice.

3. A whole property launch campaign from one form

A developer enters a project once: name, location, price, target buyer, incentives, brand book, masterplan and renders. The system builds a Google Drive folder tree and a tracker row with a project ID and slug, then makes one Gemini call that returns the entire bilingual content library as structured JSON. That payload is parsed, saved to Drive and fanned out to separate workflows for the HubSpot landing page, posters, video reels through JSON2Video, and a Meta ads campaign, which was deactivated in the build shown. Apollo supplies a targeted outreach list.

6. UploadGoogle Drive
7. Update statusGoogle Sheets
8. Repackage payload
9. Call landing page, poster, reels workflows

One structured call rather than twenty separate prompts is deliberate: every piece of copy comes from the same brief, so the landing page and the ads never contradict each other.

4. AI email support that knows when not to answer

Each incoming Gmail message is classified by intent, then searched against a knowledge base using embeddings. The matching passages become context for the response model, which returns a structured answer with a confidence score. Above the threshold the reply is sent and logged as resolved; below it the email goes to a review queue and the support team is alerted in Slack. A second, weekly workflow summarises the logs and posts the digest to email and Slack.

3. Classify intent
4. Search knowledge baseembeddings
5. Build context
6. Generate response
7. Confidence check
8. Auto-send and log
9. Or: review queue, Slack alert

The confidence check is the whole point. An AI that answers everything is a liability; one that escalates what it is unsure of is a colleague.

5. Shipping labels the moment an order is paid

A paid WooCommerce order triggers it. The workflow extracts the order, validates the address through the Shippo API, calculates weight and dimensions, fetches rates, selects the carrier and generates the label. It then updates the order in the store, downloads the label PDF, saves it to Google Drive and emails the team and the customer. A bad address or a failed label each raise their own alert.
