SMS Applet

The SMS applet sends an SMS message during a call flow. Use it to send confirmation messages, follow-up information, or notifications triggered by call events.

Modes​

Static Mode​

Send a fixed, pre-configured message to the caller.

  • Configure the message text directly in the applet
  • The same message is sent every time

Dynamic Mode​

Fetch the message content from your application URL.

  • The applet sends a GET request to your configured URL
  • Your application returns the SMS content as plain text
  • Enables personalized messages based on caller data or call context

Configuration​

  1. In the Exotel Dashboard, open your call flow editor
  2. Drag the SMS applet into your flow
  3. Choose the mode:
    • Static: Enter the message text
    • Dynamic: Provide your application URL

Example Flows​

Post-call confirmation:

Incoming Call → Connect (to agent) → SMS ("Thank you for calling. Your ticket #12345 has been created.")

Dynamic follow-up:

Incoming Call → Passthru (look up order) → SMS (fetch order status from URL) → Hangup

Dynamic Mode Response Format​

Your application URL should return the SMS content as plain text in the response body. The applet sends a GET request and expects a simple text response.
