How do I set up SMS in Vapi using a Twilio phone number?

To set up SMS in Vapi with your Twilio phone number, use the API to enable SMS by setting

smsEnabled: true

when creating or updating the number. Here’s a sample cURL command:

bash
curl -X POST https://api.vapi.ai/phone-number \
  -H "Authorization: Bearer <token>" \
  -H "Content-Type: application/json" \
  -d '{
    "provider": "twilio",
    "smsEnabled": true,
    "credentialId": "<your_twilio_credential_id>"
  }'

Make sure your Twilio number is US-based and SMS-enabled. For more details, see the [Vapi Inbound SMS guide](https://docs.vapi.ai/phone-numbers/inbound-sms). Source: - [Inbound SMS](https://docs.vapi.ai/phone-numbers/inbound-sms)

I’m going to send SMS messages to users after scheduling an appointment, as well as confirmation SMS messages for users to confirm their appointments.
