Quick overview
Quick overview This workflow accepts emergency location requests (or runs on a 5-minute schedule), finds and ranks nearby hospitals/clinics using Google Places, capacity data, and Google Distance Matrix, generates a routing message with OpenAI, sends the recommendation via Twilio SMS, logs the event to Google Sheets, and returns a JSON response. How it works Receives an emergency request via a webhook POST (or runs every 5 minutes on a schedule) and normalizes latitude, longitude, severity, phone number, and a request ID. Validates the GPS coordinates, maps severity to a numeric score, and sets a search radius, returning an error response if the location is invalid. Queries the Google Places API for nearby hospitals and clinics, then merges and deduplicates the results into a single facility list. Looks up each facility’s ED capacity metrics from a capacity API and calculates real-time driving time to each facility with the Google Distance Matrix API. Scores and ranks facilities using a severity-adjusted composite score (travel time, available beds, wait time, and ED diversion penalties) and selects the best match plus two alternatives. Uses OpenAI to generate a calm routing message, formats an SMS with a Google Maps link, sends it via Twilio, logs the routing event to Google Sheets, and returns the recommendation as JSON to the caller. Setup Copy the webhook URL from n8n and configure your client/app to POST latitude, longitude, severity, and phone to the workflow. Provide a Google Maps API key (Places API and Distance Matrix API enabled) and replace YOUR_GOOGLE_MAPS_API_KEY in the Google Places and Distance Matrix request URLs. Configure the capacity lookup endpoint used in the “facility-capacity” HTTP request (or replace it with your own API) so it returns ed_status, available_beds, and wait_time_minutes. Add Twilio HTTP Basic Auth credentials (Account SID and Auth Token) and replace YOUR_TWILIO_ACCOUNT_SID and YOUR_TWILIO_NUMBER in the SMS request. Add an OpenAI API credential and select the model you want to use for generating the routing message. Add Google Sheets OAuth2 credentials and replace YOUR_SHEET_ID, and ensure the EmergencyLog sheet tab exists with the expected columns for the appended row.
