Twilio

Send SMS, make calls, and verify OTPs with Twilio's cloud communications platform

Twilio provides programmable SMS, voice, and messaging APIs used by thousands of applications worldwide. CipherSense Agents integrates with Twilio to send text messages, initiate outbound voice calls with TwiML, deliver OTPs via Twilio Verify, and receive inbound SMS to trigger workflows. Twilio also supports sending WhatsApp messages through its own sender as an alternative to the Meta direct API.

Get or buy a Twilio phone number
