Questions about this workflow
Does this workflow find a phone number in every calendar event?
The trigger returns event details and attendees, but a usable phone number must be present in the event data or supplied to Notis.
What number format does Callerapi require?
Use an E.164 formatted number. Notis can report the number's detailed reputation, business, carrier, and FTC complaint information.
Can it automatically block a caller?
No. The available Callerapi action retrieves phone number information; it does not block or manage calls.
