Call transcripts. To get the transcript and an AI summary of your Zoom calls with contacts, connect Zoom in Meetings > Connected calendars > Call recordings. See Call transcripts and summaries. This page is about webinar registrants.
Pro plan. Zoom sends people to a campaign’s trigger URL, and trigger URLs are part of Pro and Agency (and the free trial). Anything you already have keeps working on every plan. See Plans and billing.
Ask for the LinkedIn profile in your webinar registration. Each new registrant goes through Zapier (or Make, or n8n) to the campaign’s trigger URL: a connection request before the event, a follow-up with the recording after.
How it connects: Zapier’s Zoom app (new webinar registrant) and Webhooks by Zapier. Zoom’s own webhooks check each endpoint with a validation challenge that the receiving app must answer; Kerux trigger URLs don’t do that handshake, so Zapier, Make or n8n sits in between.

​
Before you start

  • Zoom: a Zoom Webinars license and registration turned on for the webinar.
  • Zapier plan: Webhooks by Zapier needs a paid plan.

​
1. Ask for the LinkedIn URL

In Zoom, edit the webinar’s registration and add a custom question “LinkedIn profile URL”.

​
2. Copy the trigger URL

In Kerux, open the campaign, click + Add on the Trigger half of the start box and choose Incoming webhook (API). Click Add, then Copy link.

​
3. Build the Zap

1

Trigger

Zoom’s new webinar registrant trigger. Connect Zoom, pick the webinar, load a test registrant.
2

Action

Webhooks by Zapier > POST, URL the trigger URL, Payload Type json.
3

Data

linkedin_url (the custom question’s answer), first_name, last_name, email, and custom__webinar with the webinar’s topic.
What Kerux receives:
Kerux answers 202 with { "data": { "enrolled": 1, "already_in": 0, "lead_ids": ["..."] } }.

​
4. The campaign

A connection request mentioning {{contact.custom.webinar}}, a wait until the day after the event, then a message with the recording. For attendees versus no-shows, send each group from Zoom’s attendee report to a different campaign with the same kind of Zap.

​
Test with one contact

Register for your own webinar with your LinkedIn URL and check that you appear in the campaign’s contacts.

​
Common errors

linkedin_url is missing: the custom question wasn’t answered or isn’t mapped.
Registration is off for the webinar, or the Zap watches another webinar.
