Restaurant operators know the pain: phone calls interrupting service, reservations scattered across multiple systems, and staff juggling between POS terminals and reservation platforms during peak hours. The solution lies in seamless integration between your AI phone system and existing restaurant technology stack.
Hostie AI transforms this chaotic workflow into a streamlined operation that handles calls, texts, and emails while syncing directly with your Toast POS system (Hostie AI). The integration process, which can be completed in under 60 minutes, involves connecting your virtual host to Toast's API endpoints and configuring webhook mapping for real-time table status updates (Step-by-Step Integration Guide).
This comprehensive guide walks Toast operators through every step of connecting Hostie AI's virtual host to Toast POS and reservation partners like OpenTable. We'll cover prerequisite API keys, webhook mapping for real-time table status, and provide a complete testing checklist for bidirectional data flow (2025 Integration Guide).
Modern restaurants face unprecedented operational challenges. High-volume restaurants receive between 800 and 1,000 calls per month, which can disrupt service and overwhelm staff (2025 Buyer's Guide). Toast POS is a leading point-of-sale and restaurant management platform that caters to foodservice businesses of all sizes, allowing guests to order and pay directly at the table, through a kiosk, or via their own mobile devices (Step-by-Step Integration Guide).
Integrating a virtual host with a Toast POS system can transform a restaurant's phone operations from chaotic to seamless (Virtual Host Integration Guide). The integration process is not just technical but also operational, requiring systems that work reliably during peak times (Virtual Host Integration Guide).
Hostie AI handles over 80% of guest communications automatically for partner establishments like Flour + Water and Slanted Door (2025 Integration Guide). After integrating Hostie with partner establishments such as Flour + Water and Slanted Door to help their teams enhance their guest communication management, restaurants now handle over 80% of their guest communications automatically (Hostie AI).
Before diving into the integration process, ensure you have the following components ready:
Client ID: [Your unique identifier]
Client Secret: [Your secure token]
Restaurant GUID: [Location identifier]
Before proceeding, verify your API connection:
curl -X GET "https://ws-api.toasttab.com/restaurants/v1/restaurants/{restaurantGuid}/menus" \
-H "Authorization: Bearer {access_token}" \
-H "Content-Type: application/json"
A successful response indicates your API credentials are properly configured.
Hostie AI is an AI-powered communication platform that helps restaurants handle calls, texts, and emails automatically and around the clock (Hostie AI).

Successful webhook delivery ensures bidirectional data flow between systems.
Zero-touch reservations allow calls to flow directly from Hostie's AI system to the restaurant's POS and kitchen display systems without any human intervention (2025 Integration Guide). Restaurant IT managers are increasingly looking to integrate AI-powered voice systems, reservation platforms, and point-of-sale systems to streamline operations and maintain high-quality guest experiences (2025 Integration Guide).
With all three systems connected, reservation data flows seamlessly:
Hostie AI's voice agent can be integrated with OpenTable's Connect API and Toast's new Voice Ordering beta, released in June 2025, to achieve zero-touch reservations (2025 Integration Guide).
