Hi Team,

For the WebHook implementation, does zoom support mTLS authentication or is HMAC the only way?

TIA!

Hi @Ekansh  
Thanks for reaching out to us!  
We support two ways to verify webhooks

> **[Using webhooks - API - Zoom Developer Docs](https://developers.zoom.us/docs/api/webhooks/#verify-webhook-events)**
>
> Learn how to configure and implement webhooks to receive real-time Zoom events, verify webhook authenticity, and manage subscriptions via build flow or API.

Zoom offers the following options to verify webhooks with your own header:

- [Basic Authentication](https://developers.zoom.us/docs/api/webhooks/#basic-authentication)
- [Token Authentication (OAuth)](https://developers.zoom.us/docs/api/webhooks/#token-authentication-oauth)
- [Custom Header](https://developers.zoom.us/docs/api/webhooks/#custom-header)
