Twilio Communications

This is a solid foundation for Twilio integration that covers the three main use cases: sending SMS messages, handling 2FA with Twilio Verify, and building IVR phone menus with TwiML. The patterns include proper error handling, phone number validation for E.164 format, and webhook security validation. The Verify pattern is the standout here since it saves you from rolling your own OTP system and gets you built-in fraud prevention. The IVR example shows the basics of gathering touch-tone input and routing calls. Use this when you need to add phone-based features to your app and want working code that handles the common gotchas like message segmentation costs and rate limits.

Patterns

SMS Sending Pattern

Basic pattern for sending SMS messages with Twilio. Handles the fundamentals: phone number formatting, message delivery, and delivery status callbacks.

Key considerations:

Phone numbers must be in E.164 format (+1234567890)
Default rate limit: 80 messages per second (MPS)
Messages over 160 characters are split (and cost more)
Carrier filtering can block messages (especially to US numbers)

When to use: ['Sending notifications to users', 'Transactional messages (order confirmations, shipping)', 'Alerts and reminders']

from twilio.rest import Client
from twilio.base.exceptions import TwilioRestException

class TwilioSMS:
    """
    SMS sending with proper error handling and validation.
    """

        self.client = Client(
            os.environ["TWILIO_ACCOUNT_SID"],
            os.environ["TWILIO_AUTH_TOKEN"]
        )
        self.from_number = os.environ["TWILIO_PHONE_NUMBER"]
