## How it works When AI Agent picks up a call it is serving your customers according to the AI Agent settings and prompt (instructions). When you enable an **Appointment Booking** tool, your agent is able to make appointments booking on behalf of your customers When customer calls and asks to make a booking, your agent inserts an event onto your Google Calendar. Booking notification can be sent via SMS and email. You can also enable *webhook* setting to handle booking on your infrastructure programmatically

## Booking destinations ### Google Calendar Link your Google Calendar to get bookings submitted as events on your calendar. Receive Google event notifications to email attendees. Setup reminders (popups and by email). Define timezone in which is processed a time taken from customer (can be different from your default calendar's timezone)

### SMS notification Send booking notification to any number by SMS. For a source number (used as a number where SMS is sent from) select any of your numbers ( [Number](/components/number.md) ) or use *Auto* option to send from automatically assigned number (no need to own number just to be ble to send SMS notification) Enable/disable option to send booking confirmation to customers

### Email notification Send booking notification to any email addresses

### Webhook POST a booking notification to REST endpoints

## Booking parameters In your automated process for taking appointment bookings you often need to collect specific data from the customer. How do you customise appointment booking to do that? As always, you start from a clear prompt instructions that tells your [AI Agent](/features/ai-agent.md) exactly what to do. If you need to collect specific information from customers you should tell your agent about it The more detailed your prompt is the better

But prompt instructions alone is not enough for AI Agent to reliably collect all the information from your clients. And so we came up with a more trustworthy solution: booking parameters This is where you define data that needs to be collected

Don't need a customer to tell their name?

Not a problem ✅

But need them to tell their car make and model?

Just add it as a new parameter! ✅

Parameters guarantee that booking submitted by the agent will always have all the information you expect to get from your customers

And then, you enjoy notifications coming to the channels you've enabled with all the information that you need to serve your clients up to the standard you've set up for your business

Here is how to setup and deploy an AI Agent for appointment bookings, and a demo call with all notifications triggered {% embed url="" %} --- # Agent Instructions This documentation is published with GitBook.
