Webhooks & Automations
Every call, delivered to your systems.
A webhook is simple: when something happens on a call, Nixflex sends the details to a URL you choose - automatically, the second it ends. No polling, no exports, no copy-paste.
LIVE: WHAT HAPPENS WHEN A CALL ENDS

Down? We retry automatically.
01
Set a URL
One field on any phone number - dashboard or API. A second URL can receive the same events.
02
Calls just happen
Inbound or outbound, phone or web - when a call ends, the full record is assembled.
03
You receive everything
Transcript, summary, sentiment, extracted data, bookings, recording link - one POST, retried automatically if your server is down.
THE REAL PAYLOAD
This is the actual shape every call.completed event carries - build against it directly.
