- In the "URL" field you can enter the URL above.
- Then check boxes for all events, because we want this webhook to listen for everything.
This includes:
- "Contact events to send" -> "Created", "Updated", and "Deleted"
- "Email events to send" -> Deleted" "Clicked", "Opened", "Bounced",
  "Complained", and "Unsubscribed"
- You can keep the checkboxes under "Exclude contact events that occur" unchecked.

- Save the endpoint.

You'll be dropped back on the Webhooks page.
Click 'View Secret' next to the endpoint you added, and Copy it.
We'll use it for webhook verification.)
