For my company internal use, will it be doable to set a webhook to company internal domain name or url?

Hi ​@DongSheng83307  —  Thanks for reaching out!

Calendly webhooks are designed to send webhook event data to the endpoint URL you specify, so if your company URL is publicly reachable, that should fit the expected webhook setup.

However, if the URL is only available inside your private network or behind a VPN, the safer approach is to expose a public HTTPS endpoint for the webhook and then route the payload internally from there.
