Review missed-call numbers where your team discusses them

Let a Slack note about a missed call prompt a Callerapi lookup, so the number's available details are ready for review.

Trigger

Channel Message Received

Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.

Action

Get Phone Number Information

Tool to retrieve detailed information about a specific phone number, including reputation, business and carrier details, and ftc complaints. use when the number is in e.164 format and set hlr=true to include hlr data (adds 1-3 seconds to response).

  • Keep the lookup attached to the team's existing workflow.
