Summary

Twilio Studio is a low-code/no-code visual builder for creating, editing, and managing communication workflows. Users arrange widgets on a canvas and can add code for custom logic. Flows can start from inbound messages, voice calls, webhooks, or other Studio Flows, and can handle voice, messaging, and other communication applications. Studio can exchange data with backend systems to add context to Twilio-powered conversations. Twilio lists IVRs, appointment reminders, SMS surveys, call center workflows, autoresponders, and call forwarding as use cases. Its documentation includes tutorials for Slack, WhatsApp customer support menus, Twilio Conversations, and RCS messaging. The free tier includes 1,000 flow executions per month. A Flow can contain up to 2,000 widgets, including Subflows; an Execution ends after 1,000 steps or 30 days, and Execution and Step data is retained for 30 days after an Execution starts. Outbound HTTP requests from specified widgets are limited to 10 seconds. Additional Twilio communications charges are separate.
