Twilio Studio

What it does: Twilio Studio is a low-code/no-code visual builder for creating, editing, and managing communication workflows.
Channels: Studio workflows can handle voice, messaging, and other communication applications.
Visual builder: Users build workflows by dragging widgets onto a canvas and can add code for custom logic.
Triggers: Flows can be triggered by inbound messages, inbound voice calls, webhooks, or other Studio Flows.
Integrations: Studio documentation includes tutorials for Slack, WhatsApp customer support menus, Twilio Conversations, and RCS messaging.
Backend connections: Studio can send data to and from backend systems to add context to Twilio-powered conversations.
Use cases: Twilio identifies IVRs, appointment reminders, SMS surveys, call center workflows, autoresponders, and call forwarding as Studio use cases.
Execution data retention: Studio retains Execution and Step data for 30 days after an Execution starts.
Flow limits: A Flow is limited to 2,000 widgets including Subflows, and an Execution ends after 1,000 steps or 30 days.
Request limit: Outbound HTTP requests from the HTTP Request and Run Function widgets are limited to 10 seconds.
PCI limitation: Studio does not support the PCI Mode setting in Programmable Voice, and its Gather Input widget does not redact collected Gather data.
Authentication: Studio automatically generates an API key for Twilio API requests during a Flow Execution, so users do not need to provide their Twilio Auth Token to Studio.
Support: Twilio directs Studio users to its support team and the Twilio tag on Stack Overflow for help.
Security certifications: Twilio states that its services are certified under ISO/IEC 27001 and have attestations to ISO/IEC 27017 and ISO/IEC 27018.
