Notis

Give priority contact checks a simple signal

Mark a message for a lookup as you read it, and let Notis retrieve Callerapi information for review.

Trigger

Message Reaction Added

Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.

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).

Why this helps

Small follow-ups compete with bigger tasks and can vanish from memory before you get back to them.

  • Turn a reaction into a clear request for a lookup.
  • Reduce the need to remember a second manual search.
  • Keep the result associated with the message that mattered.

Setup

Build it in a few focused steps.

  • 1Connect Slack and Callerapi to Notis once through the portal.
  • 2Create an automation and write one prompt explaining how to identify marked priority numbers.
  • 3Pick Message Reaction Added and set an emoji filter if available.
  • 4Choose a channel for run reports and test on a message with an E.164 number.

Questions about this workflow

Can this prioritize the number automatically?

The reaction can request a lookup. The listed Callerapi action retrieves information but does not assign priority or create tasks.

Can I choose a dedicated reaction?

Yes. The Slack trigger supports optional emoji filtering.
