WhatsApp Emergency Notification System
Receives a WhatsApp message, looks up the sender's address in Google Sheets, and alerts the on-duty staff for that specific zone.
What it does
Receive instant WhatsApp alerts when someone contacts you, automatically matched to your zone using a lookup in Google Sheets so you know exactly who needs help immediately. This ensures the right staff member gets notified for every emergency without manual checking.
Step by step
- Configure a webhook endpoint in your application server to receive incoming POST requests from the WhatsApp Business API.
- Map the incoming phone number field to a query parameter for retrieving data from Google Sheets using the Google Sheets API v4.
- Implement logic to parse the JSON response from Google Sheets and extract the designated contact's phone number for the specific area.
Where the LLM does the work
- Generate the natural language template for the emergency notification message that includes dynamic variables like the user's name or location details.
- Draft error handling messages that explain system failures to the end-user without exposing internal technical stack information.
- Create a mapping strategy for area codes to designated personnel if the Google Sheets structure requires complex conditional logic.
Watch out for
WhatsApp API phone number verification can take time so ensure you have a sandbox environment ready for initial testing before going live.
Phone number formatting must be consistent with E.164 standards otherwise the WhatsApp Business API will reject the notification request.
Sensitive user data is transmitted in this flow so encrypt all payloads in transit and restrict Google Sheets access via OAuth2 service accounts.

The agent brief
Everything your agent needs, including the gotchas. Copy it and go.
You are helping me build the following AI agent workflow. ## Goal WhatsApp Emergency Notification System: Receives a WhatsApp message, looks up the sender's address in Google Sheets, and alerts the on-duty staff for that specific zone. ## Specification - What it does: Receive instant WhatsApp alerts when someone contacts you, automatically matched to your zone using a lookup in Google Sheets so you know exactly who needs help immediately. This ensures the right staff member gets notified for every emergency without manual checking. - Trigger: Triggered by an event (Event · on WhatsApp message) - Autonomy: Fully hands-off - Expected setup effort: under an hour - Tools/services involved: - WhatsApp: Trigger and notification delivery - Google Sheets: User lookup and address retrieval ## Known pitfalls, handle each one explicitly in your implementation 1. WhatsApp API phone number verification can take time so ensure you have a sandbox environment ready for initial testing before going live. 2. Phone number formatting must be consistent with E.164 standards otherwise the WhatsApp Business API will reject the notification request. 3. Sensitive user data is transmitted in this flow so encrypt all payloads in transit and restrict Google Sheets access via OAuth2 service accounts. ## Reference implementation https://www.youtube.com/watch?v=GIZzRGYpCbM (workflow template) Fetch and inspect this before building. If it matches my stack, adapt it; if not, rebuild the pattern with my tools. ## Process requirements 1. Before building: ask me which of the listed tools I actually use and what my platform is (n8n / Make / code / other). Do not assume. 2. Adapt the pattern to my answers; do not force the reference stack. 3. Address every pitfall above; tell me how you handled each. 4. Provide a test plan I can run before letting this touch real data. 5. Ask before any step that sends messages, modifies data, or spends money.

Frequently asked questions
Can I use a different Messaging than WhatsApp?
Yes. WhatsApp is only the example messaging in this recipe. The same flow works with ClickSend API, Discord, Google Chat and LINE Messaging API. Swap the messaging connection and keep the rest of the setup as written.
