twilio-webhook-architecture

Overview

Twilio delivers events to your application via HTTP callbacks (webhooks). Inbound messages and calls trigger webhooks that expect a TwiML response; status callbacks and event streams push delivery and lifecycle data asynchronously. This skill covers the cross-product patterns that apply to every webhook integration.

Prerequisites

• Twilio account with a phone number or service configured with a webhook URL -- New to Twilio? See twilio-account-setup
• TWILIO_ACCOUNT_SID and TWILIO_AUTH_TOKEN -- see twilio-iam-auth-setup
• SDK: pip install twilio flask / npm install twilio express
• Publicly accessible HTTPS endpoint (see Local Development section below)
