This guide builds an agent that handles bookings and questions over SMS. Callers text your number, and the agent replies, checks your calendar, and books appointments — all in a text conversation, no call required.

​
What you’ll build

An SMS agent that:
  • Replies to incoming texts on your number
  • Answers questions and books appointments over text
  • Uses the same calendar connection as your voice agent
The SMS agent shares the booking tools connected to the number. If your number can book over a call, it can book over text — no separate setup.

Before you start

​
Steps

1

Write the SMS agent's instructions

The SMS agent uses its own text prompt, so you can shape how it writes — shorter and more direct than speech. Tell it what it can do.

Let it book over text

Because booking tools are connected to the number, the SMS agent can check availability and book appointments the same way the voice agent does — the caller just does it by text instead of by voice.
3

Test the conversation

Text your number and ask for an appointment. The agent should:
  • Reply in text
  • Offer times that are open on your calendar
  • Confirm the booking once you choose a slot
Check your calendar — the appointment should be there, just as it would be from a call.
