Recheck a meeting number after event changes
When an existing event is updated, refresh the phone details you rely on before deciding how to follow up.
Trigger
Event Updated
Triggers when an existing Google Calendar event is modified. Returns the event ID, change type, and the specific fields that changed with their previous and new values.
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
Changes to an event can make previously reviewed caller details easy to overlook or stale.
- Tie a fresh lookup to an event update.
- Review the changed event alongside current number information.
- Reduce the chance of relying on an old phone check.
Setup
Build it in a few focused steps.
- 1Connect Google Calendar and Callerapi once in the Notis portal.
- 2Create an automation in Automations, New Automation, and name it for updated event checks.
- 3In one instruction, ask Notis to look up the supplied E.164 number associated with the updated event and include the available Callerapi details in the run report.
- 4Pick Event Updated as the trigger and choose where run reports go.
- 5Test with one real event update that includes a phone number.
Questions about this workflow
Does the trigger say exactly which event fields changed?
Yes. Event Updated returns the event ID, change type, and specific fields with their previous and new values.
Can the workflow know which phone number to check?
The number must be present in data available to Notis or supplied in your instruction or related input. The trigger does not promise a phone number field.
Can this automate verification codes?
No. The available Callerapi action retrieves information about a number; it does not send or validate a verification code.
