Toast is built for restaurants. It handles your orders, payments, menu management, and staff scheduling. What it doesn't do well is customer messaging. The built-in marketing tools are limited to email, and for restaurants with an international customer base, email isn't where the conversation happens.
DMHub connects Toast to WhatsApp, turning every transaction into an opportunity for engagement, feedback, and repeat business.
What You Can Automate
Once Toast and DMHub are connected, these workflows run automatically:
- Order confirmations via WhatsApp for online and phone orders
- Pickup/delivery ready notifications when the order is complete
- Digital receipts sent after dine-in payments
- Review requests 2 hours after the meal
- Loyalty point updates after every qualifying purchase
- Win-back campaigns for customers who haven't visited in 30+ days
Step-by-Step Setup
Step 1: Connect Toast
- In DMHub, go to Settings > Integrations > Toast
- Enter your Toast Restaurant External ID
- Authenticate with your Toast partner credentials
- Select data to sync: orders, customers, menu items, payments
Step 2: Map Your Data
Toast customer records sync with DMHub contacts. The system matches on phone number first, then creates new contacts for unmatched customers. Menu items sync for use in WhatsApp ordering.
Step 3: Create Automations
Start with the highest-impact automations:
Online order ready:
- Trigger: Toast order status changes to "Ready"
- Message: "Your order from {{restaurant}} is ready for pickup! Order #{{order_number}}"
Post-dine-in feedback:
- Trigger: Dine-in check closed
- Delay: 2 hours
- Message: "Thanks for dining with us today! How was everything? Reply 1-5."
Monthly spending milestone:
- Trigger: Customer total spend crosses $200, $500, $1000
- Message: Personalized thank-you with a reward
Step 4: Enable WhatsApp Ordering
For phone orders that currently tie up your staff, set up a WhatsApp ordering flow:
- Customer messages your WhatsApp number
- DMHub's AI agent presents your Toast menu
- Customer selects items in natural language
- Order is confirmed, payment link sent, and the order flows to Toast
This frees up phone lines during rush hours and gives you a written record of every order.
Why Restaurants Choose This Integration
Speed: Toast events trigger WhatsApp messages in under 10 seconds.
Accuracy: Menu prices, item availability, and modifiers sync from Toast in real-time. No manual updates needed.
Data richness: Toast provides detailed transaction data (items, modifiers, payment method, tips, server) that DMHub uses for segmentation and personalization.
Use Cases
BBQ restaurant in Austin: Post-meal review requests generated 180 new Google reviews in 3 months. Local search ranking improved from position 8 to position 3.
Fine dining in New York: VIP customer detection based on Toast spending data. When a customer who's spent over $2,000 makes a reservation, the host is notified via WhatsApp with their preferences and dietary requirements.
Taqueria chain in Mexico City: WhatsApp ordering handles 35% of takeout orders. Kitchen staff report fewer errors compared to phone orders because the written order is unambiguous.
