Can zp-make-call in Smart Embed auto-dial without user clicking?

API and Webhooks
1

We’re building an Outlook add-in (web app) and want to add a “Call Client” button. When clicked, it should open Zoom Phone and automatically dial the number without the user needing to click again.

We’ve read the Smart Embed docs and see zp-make-call with an autoCall parameter. Questions:

  1. Does autoCall: true work in 2026 or does it still require a manual click?

  2. Does Smart Embed work inside an iframe inside an Outlook add-in (Office.js context)?

  3. Is there a REST API alternative to initiate an outbound call without Smart Embed?
