Check an unfamiliar number from Slack
When a number catches your attention, ask Notis in a Slack DM to fetch Callerapi details for you to review.
Trigger
Direct Message Received
Triggered when a new direct message (DM) is sent to a user in Slack. Catches all DMs across all DM channels.
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
Unknown calls can interrupt focused work and leave you deciding whether to spend time searching for the number.
- Start a lookup with a short DM to Notis.
- Review available number details before deciding on a next step.
- Avoid reopening the question later because the lookup was never done.
Setup
Build it in a few focused steps.
- 1Connect Slack and Callerapi to Notis once in the portal.
- 2Create an automation from the portal or by telling Notis what you want in plain language.
- 3Use one prompt that describes looking up unfamiliar E.164 numbers shared in a DM.
- 4Select Direct Message Received, choose a run-report channel, and test with one real number.
Questions about this workflow
Does the lookup tell me whether I should answer?
It provides Callerapi information for review; the action does not make that decision for you.
Do I need to format the number?
Yes. The action specifies E.164 format.
