Use cases

Here are some common ways to use Twilio in your Voiceflow agent's workflow:

• Send a confirmation code during an onboarding process.
• Deliver appointment reminders to customers.
• Send order updates or tracking links.
• Share follow-up information after a customer service conversation.

Example:

If a customer says, “Can you text me the order tracking link?”, the agent might use Send SMS to send the link to their phone number.

Ensure you provide an LLM description for the tool so the agent understands when to use it.

E.g. for Send SMS, you might write: Use this when the user asks to receive information or updates via text message.

👀

Be wary of each action's required arguments.

The Send SMS action requires at least a to phone number and a message body. Decide whether these should be defaulted, hardcoded, or collected by the agent. Always provide LLM descriptions for each input so the agent knows exactly how to use them.
