Twilio

Presentation

Twilio is a cloud communications platform that lets businesses add messaging, voice, video and email to their own applications through APIs. Rather than building telecom infrastructure from scratch, teams call Twilio's services to send an SMS, place a call, run a video session or deliver transactional email. It powers everything from appointment reminders and two-factor authentication to full customer engagement platforms, and it scales from a single startup script to enterprise-grade volume.

How it works

Twilio exposes each communication channel as a programmable building block. A developer connects to a REST API or SDK, provisions a phone number or sender, and triggers messages or calls from their app or backend. Because it is API-first, Twilio slots into existing workflows and automations: an order status can trigger an SMS, a signup can trigger a verification code, a support event can trigger a call. Add-ons and integrations extend the platform with data enrichment, analytics and security, while the same APIs remain consistent as your needs grow across more than 180 countries.

Features

• Messaging API: send and receive SMS, MMS and chat globally for marketing and support.
• Voice API: programmable calls with IVR, call tracking and phone verification.
• Video API: embed video calling for telehealth, education and collaboration.
• Email (SendGrid): high-volume transactional and marketing email with delivery tracking.
• Programmable wireless and IoT: connectivity for fleets of connected devices.
• Marketplace add-ons: pre-integrated partner tools for data, analytics and security.

Use cases

Twilio adapts to many industries. E-commerce sends order updates and personalised notifications; healthcare runs telehealth sessions, appointment reminders and secure patient messaging; financial services deploy fraud alerts, verification and automated voice; education supports remote learning and mass messaging to students and parents; logistics keeps customers informed with real-time updates. In a no-code or Webflow project, Twilio is typically wired in through an automation platform to send confirmations, alerts or verification codes triggered by form submissions or CRM events.
