Is it possible to detect Zoom Phone "In-Call" status using a "Webhook Only" app for Zapier?

API and Webhooks
1

I am trying to build a system that detects when a user is on a Zoom Phone call and updates their status in a Google Sheet via Zapier.

I have been trying to set this up using a “Webhook Only” app in the Zoom App Marketplace. However, I am having trouble finding the specific events for call start and end in the Event Subscriptions list.

Could you please clarify the following?

[Goal] Detect Zoom Phone “In-Call” status and send the data to a Zapier Webhook URL.

[Required Data]

  • Call Started (To mark as “In-Call”)

  • Call Ended (To mark as “Available”)

  • The user’s email address (To identify the person in our Google Sheet)

[Specific Questions]

  1. Is it possible to achieve this goal using a “Webhook Only” app?

  2. To get real-time call status, which specific Event Subscriptions should I select? For example, should I look into “Call Log”, “User Activity”, or another category?

  3. If those events are not appearing in my list, what are the exact steps or requirements (e.g., specific admin settings or licenses) to make them visible?

I would appreciate any detailed instructions on the necessary settings. Thank you!
