Note: The SMS functionality described here requires a Twilio account. You will also need to register your secret Twilio keys with Conclude. Conclude needs this information in order to send SMS on your behalf.

If you don’t have a Twilio account:

  1. Sign up for a Twilio account at
  2. Create and take note of the information at

    • Account SID
    • Authorization Token
    • Phone number (sender)
  3. Register the private account SID and token with an existing Conclude app as described here.

You can use triggers to send SMS messages to multiple recipients. Inside the trigger, create an sms object with these fields:

  • to: An international number starting with + and a country code.
  • body: Text to be sent. The text may contain macros and newlines (\n).
  • log (boolean): Set log to true to record information about SMSes that were sent. Default false.
  • log_body (boolean): Set log_body to true to log the text that was sent. Default false.

The example sends an SMS to someone outside your Slack workspace.

  "name": "click-me",
  "type": "button",
  "label": "Escalate!",
  "trigger": {
    "sms": {
      "to": "+16505559876",
      "body": "${title}:\n${body}"

You can also send SMSes to people inside your Slack workspace:

  "sms": {
    "to": "#dev, @product",

In the example above, Conclude will extract and send SMS to the mobile phone numbers of the members of the #dev channel and the @product user group. This will only work for the users who have registered their mobile phone numbers in their Slack profiles.
