Re-engage missed property viewings with Google Calendar, Gemini, Gmail, and WhatsApp

## Quick overview When a buyer misses a scheduled viewing, this workflow automatically sends an AI-personalized follow-up by email and WhatsApp using Google Gemini, then logs the outcome to Google Sheets, recovering leads that would otherwise go cold. ## How it works 1. Triggers every 15 minutes when a Google Calendar event is updated in the selected viewings calendar. 2. Checks the event title/summary and continues only if it contains the tag “no-show”. 3. Extracts the lead’s name, email, phone, property address, and scheduled viewing time from the calendar event details. 4. Sends the lead and viewing context to Google Gemini to generate an email message and a WhatsApp message in JSON format. 5. Parses and cleans the AI output into safe HTML for email and a trimmed plain-text WhatsApp message. 6. Sends the re-engagement email via Gmail and appends the follow-up outcome to a Google Sheets log. 7. If a phone number is available, sends the WhatsApp message and updates a Google Sheets status field to record that WhatsApp was sent. ## Setup 1. Connect credentials for Google Calendar, Gmail, Google Sheets, and a Google Gemini (PaLM) API key. 2. Select the correct Google Calendar (viewings calendar) and ensure missed appointments are consistently tagged with “no-show” in the event summary. 3. Create or choose a Google Sheets document and sheet, then fill in the document ID/URL, sheet name, and the columns expected by the append/update logging steps. 4. Configure WhatsApp credentials in n8n (or disable the WhatsApp branch) and ensure lead phone numbers are stored in the calendar event description in the expected format (e.g., Name: ... | Email: ... | Phone: ... |). ## Requirements - Before running this workflow, create a Google Sheet with these exact column headers: Record ID | Lead Name | Email | Phone | Property Address | Original Viewing Time | Email Sent | WhatsApp Sent | Email Message Text | WhatsApp Message Text | Timestamp ## Customization - Edit the AI prompt in "Draft Re-Engagement Messages" to change tone or language - Add SMS or other channels by duplicating the WhatsApp branch pattern - Adjust the "no-show" tag keyword if your calendar uses different terminology ## Additional info WhatsApp is optional. If you don't have WhatsApp Business Cloud API credentials, disable that branch — the email follow-up will still send normally. This template assumes calendar events are tagged with "no-show" in the title and include lead contact info in the event description (Name: ... | Email: ... | Phone: ... |).

Quote freight shipments via WhatsApp with Google Gemini, HighLevel, and Warp

## Quick overview Youtube Video: https://youtu.be/kO4LgKT6oME?si=VpUEz2LKuxMujrUp This workflow receives WhatsApp messages, checks the sender in HighLevel, and uses Google Gemini with Redis chat memory to collect shipment details, then requests an LTL quote from the Warp API, applies a commission, and replies with either a conversational prompt or a final freight quote. ## How it works 1. Receives an incoming WhatsApp message and only continues when the text body is not empty. 2. Looks up the sender’s phone number in HighLevel and stops contacts marked as Do Not Disturb from being processed further. 3. Uses a Google Gemini-powered agent with Redis chat memory to ask for missing contact and freight details in a fixed order, optionally creating the HighLevel contact or marking the lead as DND when the user opts out. 4. Parses the agent’s structured JSON output and checks whether the required shipment data collection is complete. 5. If data is incomplete, sends the agent’s conversational reply back to the user via WhatsApp. 6. If data is complete, posts the shipment details to the Warp LTL quote API, adds a configured commission percentage to the returned price, and sends the finalized quote back to the user via WhatsApp. ## Setup 1. Connect WhatsApp credentials for both the WhatsApp Trigger and WhatsApp “send message” actions, and configure the webhook in Meta/WhatsApp so inbound messages reach this workflow. 2. Add a HighLevel OAuth2 credential and confirm your HighLevel account has permission to search contacts, create contacts, and update the DND field. 3. Add a Google Gemini (PaLM) API credential and a Redis credential for chat memory, and ensure Redis is reachable from your n8n instance. 4. Add an HTTP Header Auth credential for the Warp API and verify the quote endpoint URL, headers, and request body fields match your Warp account requirements. 5. Adjust the commission percentage value (and any quoting assumptions like weight per pallet) to match your pricing policy.

Qualify web leads and send replies with Groq, Gmail, Sheets and Slack

## Quick Overview This workflow receives new lead form submissions via webhook, uses Groq (OpenAI-compatible Chat Completions) to score and draft a reply, then sends the email via Gmail, logs the lead to Google Sheets as a lightweight CRM, and posts a lead alert to Slack. ## How it works 1. Receives a POST request from your lead/contact form via a webhook. 2. Extracts and normalizes common form fields (name, email, message, service interest, phone, company) and stops if no email is provided. 3. Sends the lead details to Groq’s Chat Completions API to generate a lead score/tier, intent summary, urgency, a drafted reply email, and a Slack note. 4. Parses the Groq JSON response and flags leads as “hot” when the score is 8 or higher. 5. Sends the drafted reply to the lead using Gmail. 6. Appends the lead details and AI outputs to a Google Sheets “Leads-CRM” sheet and posts a formatted alert to a Slack channel. 7. Returns a JSON confirmation response to the original webhook request. ## Setup 1. Configure your form provider to POST submissions to the workflow’s webhook URL (path: `/new-lead`). 2. Add an HTTP Header Auth credential containing your Groq API key for the Groq Chat Completions request. 3. Connect Gmail OAuth2 credentials and set the desired Reply-To address (default is `[email protected]`). 4. Connect Google Sheets OAuth2 credentials and update the target spreadsheet and sheet to match your CRM columns. 5. Connect Slack credentials and choose the destination channel (default: `#leads`).
