Redirect after successful booking does not work with embedded Calendly on WordPress

Hello,

I am using Calendly Standard together with a WordPress/Elementor website.

The booking itself works correctly. A user can choose a time, complete the booking, and Calendly confirms the appointment successfully.

For the relevant event type, I have configured:

After booking → Redirect to an external site

with this URL:

https://mathematik-lernen.com/termin-bestaetigt/

The redirect URL has been saved correctly in Calendly.

The target page exists in WordPress and is publicly accessible.

However, after a successful booking, Calendly still remains on its own confirmation page and does not redirect to the external URL.

This happens both on iPad and Mac/Desktop.

Could you please clarify the official recommended solution for this setup?

• Does external redirect work reliably with an embedded Calendly booking form?
• Does the redirect need to be configured separately for each event type?
• Are there any restrictions with WordPress/Elementor embeds?
• Is there a specific embed method required for redirect-after-booking to work?
• If redirect is not supported in this configuration, what is Calendly’s recommended official method for tracking a successful booking in GA4 / Google Ads?

We would appreciate the simplest and most reliable solution.

Thank you.
