The Post Call Webhook add-on sends the call analysis and extracted fields to a web address you control after each call is analyzed. Use it to push leads into your CRM or another system. It is available on the Pro plan and above.

Before you start

You need a web address (URL) on your side that accepts incoming data, for example https://example.com/webhooks/zinng.

Turn on the webhook

Open the agent and scroll to Add-on Capabilities. Under Lead Capture, Send to your CRM, turn on Post Call Webhook.
Enter your address under Webhook URL. It is required.
Optional: choose a Model Selector for the post-call extraction.
Optional: add your own fields under Custom Extraction Fields.
Save your agent.

Each call sends JSON with these parts:

from: the caller’s number.
to: the number that was called.
transcript: a list of messages, each with a role (user or agent) and content.
call_analysis: call_summary, call_successful, user_sentiment, caller_name, caller_email, plus any custom fields you added.
