# Notifications (/docs/scheduling/notifications)

By default, attendees and hosts get an email when a booking's confirmed, moved or cancelled, with a
calendar invitation, and attendees get a reminder a day before. Webhooks always fire, whatever's on here.

Turn each one on or off in your settings, or per event type:

```ts twoslash
import { Coss } from "coss";
const coss = new Coss();
// ---cut---
await coss.scheduling.settings.update({
  email_from: "appointments@example.com",
  brand_name: "Acme Health",
  notifications: {
    confirmed: { email_host: false },
    reminder: { email_attendee: true, sms_attendee: true },
  },
});
```

The events are `confirmed`, `pending_approval`, `rescheduled`, `cancelled`, `declined` and `reminder`. To
send everything yourself, turn them all off and use [webhooks](/docs/webhooks).

Emails come from `email_from`, on one of your verified domains. Without one, they come from coss.com on
your behalf. They use fixed templates with your event type's title and your brand name, and the only link
in them is the attendee's manage link. Titles, host names and brand names can't contain links, and in live
environments they're screened for abuse when you set them, rather than each email being screened.

An SMS reminder needs `sms_from`, one of your approved numbers, and the attendee's `phone`. Getting their
consent is yours to do, and a STOP is always honored.

## Meeting links [#meeting-links]

An event type's `locations` say where it happens. `google_meet` and `microsoft_teams` create a link with the
calendar event, so they need a connected calendar from that provider: the confirmation waits briefly for it,
and it then appears on the booking with `scheduling.booking.location_ready`. For your own video vendor, use
`link` and set it after the `confirmed` webhook:

```ts twoslash
import { Coss } from "coss";
const coss = new Coss();
const bookingId = "book_01kd2m9a0b1c2d3e4f5g6h7j8m";
// ---cut---
await coss.scheduling.bookings.updateLocation(bookingId, {
  location: { type: "link", url: "https://video.example.com/room/abc" },
});
```
