[Card views, themes and publishing](/docs/cards/). [Browse the gallery](/apps/#cards).

## Data and privacy

Feed: `screenrig.appointments/v1`.

Feed documents carry source attribution. The Player supplies the feed to the card.

## Properties

For theme, background, accent and position, see [Common properties](/docs/cards/#common-properties).

Set static properties in `params`. Bind `data` to a project card data key for live values; that document holds only dynamic properties. Without a data key, put the complete configuration in `params`. Nested rows describe the contents of their parent property.

### Static properties

| Name | Type | Default | Values and limits | Description |
| --- | --- | --- | --- | --- |
| `title` | string | `"Next appointment"` | maxLength: `40` |  |
| `hour12` | boolean | `false` |  |  |
| `timeZone` | string, null | `null` |  | IANA zone; null uses the screen's zone. |
| `roomLabel` | string | `"Room"` | maxLength: `12` | Put before a short room, so "4" reads "Room 4". |
| `horizonDays` | integer | `14` | minimum: `1`; maximum: `60` | Slots further away than this are left out. |
| `staleMinutes` | integer | `30` | minimum: `1`; maximum: `1440` | A feed older than this shows how long ago it updated. |

### Dynamic properties

| Name | Type | Default | Values and limits | Description |
| --- | --- | --- | --- | --- |
| `practitioners` | array | `[]` | minItems: `0`; maxItems: `16` | Practitioners and their open slots, the same document as the screenrig.appointments/v1 feed's `practitioners`. The feed wins when present. |
| `practitioners[].name` | string |  | minLength: `1`; maxLength: `40`; Required |  |
| `practitioners[].specialty` | string | `""` | maxLength: `40` |  |
| `practitioners[].room` | string | `""` | maxLength: `14` | 4, B12 or Gym. One to three letters or digits read after the room label. |
| `practitioners[].slots` | array | `[]` | maxItems: `200` | Open appointment starts, ISO 8601 with an offset (or wall time in the screen's zone). |
| `footnote` | string | `""` | maxLength: `120` | A line at the foot: how to book. |
