Questions & Answers

Q: How can I set up a WhatsApp AI agent for my restaurant

The setup uses a WhatsApp trigger connected to your WhatsApp account, an OpenAI powered agent for responses, a menu tool to fetch current options, a Google Sheets sheet to record orders, and a Google Calendar integration to manage reservations. The process is described as a five minute build with a template and no code required.

Q: What role does Google Sheets play in the workflow

Google Sheets acts as the primary order recording and memory sheet. When customers place orders or provide contact details, the information is written to the sheet, creating a persistent log for fulfillment and future reference, ensuring data is easily retrievable during conversations or after purchases.

Q: How are reservations handled in this system

Reservations are checked for availability through a calendar tool and then created in Google Calendar. The AI prompts determine the correct start and end times, and the system stores the time slot and customer name in the calendar to complete the booking and avoid conflicts.

Q: Can customers send voice messages and still get responses

Yes, the setup includes transcription of voice messages using an audio to text process. The transcribed text is then processed by the AI to generate helpful menu information, order updates, or reservation confirmations, enabling responsive voice and text support.
