Prepare caller details for callback follow-up
When a callback request lands in Slack, retrieve the Callerapi details for the number while the request is in view.
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).
Why this helps
Callback requests can be easy to postpone when checking the number requires leaving the conversation and remembering to return.
- Start a phone-information lookup when a callback number is shared.
- Keep the lookup close to the request for follow-up.
- Reduce manual copying between chat and Callerapi.
Setup
Build it in a few focused steps.
- 1Connect Slack and Callerapi to Notis once through the portal.
- 2Create an automation with one prompt describing callback messages and number lookups.
- 3Select Slack Channel Message Received as its trigger.
- 4Choose a run-report channel and test with a callback request containing a real E.164 number.
Questions about this workflow
Does this place a callback?
No. The Callerapi action retrieves information about a number; it does not place a call.
Can I use a Slack channel dedicated to support?
Yes. Select the Slack channel message trigger and describe the relevant callback requests in the prompt.
