Events Sent

Events the plugin can send to the Stream Deck application.

The plugin and Property Inspector can send different events to the Stream Deck application:

Event	Description
setSettings	Save data persistently for the action's instance.
getSettings	Request the persistent data for the action's instance.
setGlobalSettings	Save data securely and globally for the plugin.
getGlobalSettings	Request the global persistent data.
openUrl	Open an URL in the default browser.
logMessage	Write a debug log to the logs file.

The plugin can send some additional events:

Event	Description
setTitle	Dynamically change the title of an instance of an action.
setImage	Dynamically change the image displayed by an instance of an action.
setFeedback	Dynamically change properties of items on the Stream Deck + touch display.
setFeedbackLayout	Dynamically change the current layout for the Stream Deck + touch display.
showAlert	Temporarily show an alert icon on the image displayed by an instance of an action.
showOk	Temporarily show an OK checkmark icon on the image displayed by an instance of an action.
setState	Change the state of the action's instance supporting multiple states.
switchToProfile	Switch to one of the preconfigured read-only profiles.
sendToPropertyInspector	Send a payload to the Property Inspector.

The Property Inspector can also send this event:

Event	Description
sendToPlugin	Send a payload to the plugin.

setSettings

The plugin and Property Inspector can save data persistently for the action's instance using the setSettings event:

{
    "event": "setSettings",
    "context": uniqueValue,
    "payload": {<json data>}
}

Members	Description
event	setSettings
context	A value to Identify the instance's action or Property Inspector. This value is received by the Property Inspector as a parameter of the connectElgatoStreamDeckSocket function.
payload	A JSON object which is persistently saved for the action's instance.

Note that when the plugin uses this API, the Property Inspector will automatically receive a didReceiveSettings callback with the new settings. Similarly, when the Property Inspector uses this API, the plugin will automatically receive a didReceiveSettings callback with the new settings.

The setSettings API is available since Stream Deck 4.0 for the plugin. Starting with Stream Deck 4.1, this API is available from the Property Inspector.

getSettings

The plugin and Property Inspector can request the persistent data stored for the action's instance using the getSettings event:

{
    "event": "getSettings",
    "context": uniqueValue
}

Members	Description
event	getSettings
context	A value to Identify the instance's action or Property Inspector. In the case of the Property Inspector, this value is received by the Property Inspector as parameter of the connectElgatoStreamDeckSocket function.

The plugin or Property Inspector will receive asynchronously an event didReceiveSettings containing the settings for this action:

{
  "action": "com.elgato.example.action1", 
  "event": "didReceiveSettings", 
  "context": uniqueValue, 
  "device": uniqueValue, 
  "payload": {
   "settings": {<json data>},

    }, 
    "isInMultiAction": false
  }
}

setGlobalSettings

The plugin and Property Inspector can save persistent data globally. The data will be saved securely to the Keychain on macOS and the Credential Store on Windows. This API can be used to save tokens that should be available to every action in the plugin.

This is done using the setGlobalSettings event:

{
    "event": "setGlobalSettings",
    "context": uniqueValue,
    "payload": {<json data>}
}

Members	Description
event	setGlobalSettings
context	A value to Identify the plugin (inPluginUUID) or the Property Inspector (inPropertyInspectorUUID). This value is received during the Registration procedure.
payload	A JSON object which is persistently saved globally.

Note that when the plugin uses this API, the Property Inspector will automatically receive a didReceiveGlobalSettings callback with the new settings. Similarly, when the Property Inspector uses this API, the plugin will automatically receive a didReceiveGlobalSettings callback with the new settings.

This API has been introduced in Stream Deck 4.1.

getGlobalSettings

The plugin and Property Inspector can request the persistent global data using the getGlobalSettings event:

{

The plugin or Property Inspector will receive asynchronously an event didReceiveGlobalSettingsthe p containing the global settings:

{
  "event": "didReceiveGlobalSettings", 
  "payload": {
   "settings": {<json data>}
    }
  }
}

This API has been introduced in Stream Deck 4.1.

 }
}
