AI Plumbing Damage Assessment, Cost Estimation, and Customer Engagement Supports WhatsApp, Email, API

This workflow automates plumbing assessments by processing multi-channel inputs, performing AI analysis, and integrating with CRM/ERP systems. Key nodes include Webhook for intake, Code for validation, HTTP Request for Google Vision API analysis, MongoDB for storage, Salesforce for CRM, and Email/SMS for customer notifications.\n\nTo set up, install n8n by downloading from n8n.io or use the cloud version at cloud.n8n.io. Sign up for a Google Cloud account to obtain a Google Vision API key at console.cloud.google.com. Create a MongoDB Atlas account for database credentials at mongodb.com. Set up Salesforce OAuth credentials via Salesforce Developer Console. Configure Twilio credentials at twilio.com for SMS. In n8n, add these credentials under 'Credentials' with names like GOOGLE_VISION_API_KEY, MONGO_VECTORDB_CREDENTIALS, SFDC_OAUTH_CREDENTIALS, and ERP_API_CREDENTIALS. Import the workflow JSON into n8n, then configure the Webhook node with a unique webhook URL and set authentication headers (e.g., X-API-Key). Ensure the HTTP Request node points to the Google Vision API URL with your API key. Connect MongoDB, Salesforce, and Twilio nodes with respective credentials. Validate input fields in the Code node to prevent errors like missing client IDs or invalid file types (e.g., only JPEG/PNG allowed).\n\nTo test, trigger the Webhook with a sample JSON payload containing client_id and an image. Check the MongoDB node for stored data and Salesforce for case creation. Monitor Email and SMS nodes for customer notifications. For errors like 'Missing client identification,' verify client_id in the payload. If 'Invalid API key' occurs, recheck Google Vision API credentials. Deploy by setting the workflow to active in n8n and sharing the webhook URL with your application. Regularly check execution logs for issues like file size limits (10MB max) or invalid email formats to ensure smooth operation.
