Tag Zoom webinar attendance and engagement levels in KlickTipp

Quick Overview

This workflow listens for Zoom meeting.ended webhooks, fetches past-meeting participants and approved registrants, calculates engagement (including re-joins), and tags contacts in KlickTipp as attended, fully attended, or not attended based on configurable thresholds and per-meeting tag IDs.

How it works

  1. Receives a Zoom webhook when a meeting ends and either completes Zoom’s endpoint URL validation or immediately responds with an “ok” status to avoid timeouts.
  2. Waits 60 seconds, then calls the Zoom API to retrieve all past-meeting participants with pagination.
  3. Calls the Zoom API to retrieve all approved meeting registrants (if registration is enabled) to identify no-shows.
  4. Aggregates participant sessions by email, resolves missing emails via registrant IDs, calculates attendance ratio against the actual meeting duration, and classifies each person as attended, fully attended, or not attended.
  5. For attendees, looks up the contact in KlickTipp and either tags existing contacts as attended or subscribes new contacts via the configured opt-in process with the attended tag.
  6. For fully attended attendees, adds an additional “fully attended” tag in KlickTipp, and for registrants who never joined, applies a “not attended” tag (skipping unknown contacts if they don’t exist in KlickTipp).

Setup

  1. Create a Zoom app with webhook support, enable the meeting.ended event, and add OAuth access for the required Zoom scopes (including reading past participants and registrants).
  2. Add your Zoom Secret Token to the HMAC step used for Zoom endpoint URL validation, and connect your Zoom OAuth2 credentials in the Zoom HTTP requests.
  3. Install/configure the KlickTipp community node credentials, create the attended/fully attended/not attended tags in KlickTipp, and set the correct tag IDs and the opt-in process (listId) in the workflow configuration.
  4. Update the webinar/topic matching and tag ID mapping in the classification code (and adjust the full-attendance ratio if needed), then copy the n8n webhook URL into your Zoom webhook configuration.
