Action

Why this helps
Welcoming new people while managing a busy group can leave important checks until later.
- Promptly review phone context when a member joins.
- Support a consistent group welcome and moderation routine.
- Avoid adding a separate number-check task to your queue.
Setup
Build it in a few focused steps.
- 1Connect Telegram and Callerapi to Notis once in the portal.
- 2Create an automation in Automations -> New Automation, or ask Notis to check an available member phone number after a join event.
- 3Tell Notis in plain language to proceed only if the event provides an E.164 number and to summarize Callerapi reputation, business, carrier, and complaint details.
- 4Select Telegram New Chat Member, choose a channel for run reports, and test with an event where a number is available.
Questions about this workflow
Will Telegram always provide the member's phone number?
No. The workflow should only run the lookup when an E.164 number is actually available in the event context.
Can the lookup welcome the member?
Callerapi's listed action retrieves phone information. A welcome message would require a separate action event.
