This allows for integrations to sync to the state of the application. This broadcast happens at least once a second, depending on updates. See below a full definition of the data that Ontime holds. You would use the Integrations feature to share these. If you prefer looking at code, please follow here {% hint style="info" %} The object broadcast object is formatted as below. With the type 'ontime' indicating that this is the application state update `{`\ `type: ontime,`\ `payload: (see below)`\ `}` If you prefer looking at code, please follow {% endhint %} | Key | Subkey | Description | Tyåe | | | ------------------------ | --------------------- | -------------------------------------------------------- | ------------------------------------------------ | - | | **timer** | | **Information related to running timer** | | | | | clock | Time now | number \| null | | | | current | Running countdown | number \| null | | | | elapsed | Elapsed time in current timer | number \| null | | | | expectedFinish | Expected finish for current timer | number \| null | | | | addedTime | Time added by user\*\* | number \| null | | | | startedAt | When did the timer start | number \| null | | | | finishedAt | When did the timer go past 0 | number \| null | | | | secondaryTimer | User in roll mode | number \| null | | | | selectedEventId | ID of loaded event | string \| null | | | | duration | Duration of loaded event | number \| null | | | | timerType | How is the time displayed | 'count-down' \| 'count-up' \| 'clock' | | | | endAction | What happens when this timer finishes | 'none' \| 'stop' \| 'load-next' \| 'play-next' | | | **playback** | | Playback state | 'roll' \| 'play' \| 'pause' \| 'stop' \| 'armed' | | | **timerMessage** | | **Information related to Message shown in timer** | | | | | text | Text of message | string | | | | visible | Whether the message is visible | boolean | | | **publicMessage** | | **Information related to Message shown in public view** | | | | | text | Text of message | string | | | | visible | Whether the message is visible | boolean | | | **lowerMessage** | | **Information related to Message shown in lower thirds** | | | | | text | Text of message | string | | | | visible | Whether the message is visible | boolean | | | **onAir** | | Whether onAir is active | boolean | | | **loaded** | | **Information related to loaded events** | | | | | numEvents | Number of timer events | number | | | | selectedEventIndex | Index of selected event | number \| null | | | | selectedEventId | ID of selected event | string \| null | | | | selectedPublicEventId | ID of public selected event | string \| null | | | | nextEventId | ID of next event | string \| null | | | | nextPublicEventId | ID of next public event | string \| null | | | e**ventNow / eventNext** | | **currently loaded event / upcoming event** | | | | | cue | Value of cue field | string | | | | title | Value of title field | string | | | | subtitle | Value of subtitle field | string | | | | presenter | Value of presenter field | string | | | | note | Value of note field | string | | | | colour | User defined colour | string | | | | isPublic | Whether the event should is public | boolean | | | | delay | Any rundown delays affecting the event | number | | | | timeStart | Scheduled start | number | | | | timeEnd | Scheduled end | number | | | | duration | Scheduled duration | number | | | | user0-user9 | User added data to the event \*\*\* | string | | * All times are in milliseconds from midnight * \*\* Can be negative * \*\*\* Not user by ontime
