Twilio SMS

Guide

Two-way SMS and MMS messaging. Far simpler than the voice channel.

  • Account Name (required)
  • Twilio Account SID (required)
  • Twilio Auth Token (required)
  • From Number (required) — in E.164 format, that is with the international prefix and no spaces: +393331234567

The dialog provides an Inbound Webhook URL and a Status Callback URL to configure on Twilio. Both have to be publicly reachable over HTTPS. Incoming requests are verified through the X-Twilio-Signature header, so a URL behind a proxy that alters the request body will make the verification fail.

There is a Test Webhook and a Setup Instructions section inside the dialog.
