Use the Twilio integration to send SMS messages directly from your Voiceflow agent. With this integration, your agent can notify users, send confirmations, or follow up with important information during a conversation. ## Basic usage [](https://w17llroiln.ufs.sh/f/JH4JLc5mceYkTcEeeknG49PzwjiDbWfpVlRtQEcJAv617B0Z) > 🔐 > > To use the Twilio integration, you'll need to add in your **API key SID, API key secret and Account SID** from your Twilio dashboard. This ensures your agent can securely send messages from your Twilio account. ## What you can do with Twilio The Twilio integration currently supports the following action: | Action | Description | | --- | --- | | Send SMS | Send a text message to a specified phone number via Twilio. | ## 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. > >  ## Frequently asked questions ### Can I send SMS messages to any country? > Yes, as long as your Twilio account has the appropriate permissions and phone numbers configured for that region. ### Can I personalize the SMS content? > Absolutely. You can insert Voiceflow variables into the message body to personalize the content for each recipient. ### Does sending an SMS cost money? > Yes. Twilio charges per message based on your plan and the recipient’s country. Check Twilio’s pricing for details.
