Red Canary’s phone integration allows SMS messages to be triggered as part of an automation playbook.

Adding an SMS automation action

To send an SMS message as part of an automation playbook:

1. Within any playbook, click Add Action.
2. Click SMS > Send SMS Message > Add to Playbook.
3. Enter one or more comma-separated phone numbers that should receive the SMS message. Use the complete '+' and country code, e.g., +16175551212 (E. 164 format).
   
   These can be determined dynamically using variables, such as using $Detection.marked_acknowledged_by_user.phone to message the user who acknowledged a detection.
4. Specify the Message you want to send. 
5. Click Save.
