I want to create a webhook that listens to all the events associated with my organization. Below is my request object.
var requestBody = new WebhookSubscriptionRequest
{
url = "https://00f9-2001-ee1-df19-e6e0-a953-99e6-1ea6-928c.ngrok-free.app/Calendly/Callback",
events = new stringt] { "invitee.created", "invitee.canceled" },
scope = "organization",
organization = orgUrl,
signing_key = "ABC",
};
Then I got this error:

But in the document, it looks like the group and user parameters are optional. Am I missing something?
