Setup Guide

How to connect Zoom to WhatsApp API

Connect Zoom to Zapier or Make

Use Zapier's Zoom integration (New Meeting, New Registrant, New Recording) or Zoom webhooks directly. WA.Expert receives the trigger and fires WhatsApp.

Set up meeting registration webhook

In Zoom: Apps → Marketplace → Webhooks. Subscribe to meeting.registration_created and recording.completed events. Point to WA.Expert or your Zapier webhook.

Map Zoom fields to WhatsApp variables

Map registrant phone number, name, meeting topic, start time, and join URL to WhatsApp template variables.

Schedule reminder delays

For 24-hour and 15-minute reminders: use Zapier Delay or Make Sleep. Calculate delay from meeting start_time minus reminder interval. Fire WA.Expert action after delay.

Set up recording notification

Subscribe to Zoom's recording.completed webhook. When triggered, WA.Expert sends WhatsApp to all meeting participants with the recording URL and password.

Sample Zoom → WhatsApp configuration

// Zoom Webhook → WA.Expert
// Event: meeting.registration_created
{
  "event": "meeting.registration_created",
  "payload": {
    "registrant": {
      "phone": "+919876543210",
      "first_name": "Priya"
    },
    "meeting": {
      "topic": "Q2 Strategy Call",
      "start_time": "2026-04-10T14:00:00Z",
      "join_url": "https://zoom.us/j/..."
    }
  }
}

WA.Expert handles WhatsApp API authentication, template management, and message delivery. You only pass the trigger data from Zoom — no WhatsApp API expertise needed.

FAQ

Zoom + WhatsApp — common questions

Does Zoom have a native WhatsApp integration?

Zoom does not have a native WhatsApp integration. The connection is achieved via Zoom webhooks + WA.Expert API directly, or via Zapier's Zoom integration (which supports New Meeting Registrant and New Recording triggers).

Can I send WhatsApp reminders at specific times before a Zoom meeting?

Yes — using Zapier Delay or Make Sleep, calculate the exact time before the meeting and trigger WA.Expert at that time. The 24-hour reminder and 15-minute reminder are the two highest-impact messages for Zoom attendance improvement.

Can I collect phone numbers during Zoom registration?

Yes — Zoom registration forms support custom questions. Add a "Phone Number" question marked as required. This phone number is included in the registration webhook payload and can be mapped to WA.Expert's "to" field.

Does this work for Zoom Webinars as well as Zoom Meetings?

Yes — Zoom Webinar has its own registration webhook (webinar.registration_created) which works identically to meeting registration for WhatsApp notifications. Zoom Webinar recordings also trigger the same recording.completed webhook.

What about recurring Zoom meetings?

Recurring Zoom meetings fire a registration webhook for each instance. If you want to send reminders only once (e.g., at series enrollment rather than per-meeting), use Zapier's Zap history to check if a reminder was already sent for this series.

Can I use Zoom + WhatsApp for customer demos and sales calls?

Yes — integrate Zoom with Calendly for booking (Calendly → Zoom meeting creation → WhatsApp confirmation via WA.Expert). This is the most popular stack for sales teams: prospect books via Calendly, Zoom meeting is created automatically, WhatsApp confirmations and reminders fire, post-meeting recording is delivered via WhatsApp.
