Set up a kiosk ordering integration with Toast by configuring the integration through the Toast Developer Portal and injecting orders from a self-service kiosk into Toast POS

Steps

1. Apply for integration partner status through the Toast Developer Portal and request access to the kiosk or ordering integration API scope during the partner vetting process
2. Obtain a client_id and client_secret from the Toast developer dashboard and implement the client credentials OAuth 2.0 flow to generate Bearer tokens for API calls
3. Build the kiosk ordering UI using your own interface and menu data sourced from the Toast Menus API, ensuring modifier groups and prices stay in sync with the restaurant's current Toast configuration
4. When a customer completes a kiosk order, construct a Toast order payload and POST it to the Toast Orders API endpoint for the target restaurant GUID, including line items, modifiers, fulfillment type, and any loyalty or promo identifiers
5. Handle the response to retrieve the Toast-generated check GUID and surface the order number or confirmation to the guest on the kiosk screen
6. Test the full order flow end-to-end in the Toast sandbox environment, including modifier pricing and kitchen ticket routing, before going live
