Actions

All actions are indicated as strings and are used by content items to perform specific tasks (e.g. play a video, start a slideshow, etc.). Some actions use additional data, provided by the corresponding content item.

Note: The actions described here are the main actions that are perfectly adequate for the most media pages. However, if you want to create more complex and interactive media pages, please have a look at the internal actions.

For more information about the internal actions, please see Internal Actions.

Server Actions

It is possible to execute actions on server side. For this feature, you need programming skills, because you need to implement a service for your server. Server actions allow you to provide logins, member areas, parental controls, search queries, and more. All server actions are sent as HTTP POST requests. Parallel server actions are not allowed (only one server action can be running on application side).

Note: The Content-Type header for all HTTP POST requests is set to application/x-www-form-urlencoded (instead of application/json) to ensure CORS support for simple services (by avoiding CORS preflight requests). Please ignore the Content-Type header on your server and handle all incoming data from the Media Station X application as JSON objects. Since version 0.1.90, you can set an accurate: prefix before {URL} to use the accurate headers (e.g. execute:accurate:{URL}, execute:code:accurate:{URL}, execute:user:accurate:{URL}, etc.).

Syntax of server actions

Syntax	Example	Since Version	Description
execute:{URL}	execute:http://msx.benzac.de/services/echo.php	0.1.30	Executes an action on server side and returns an action to be executed (e.g. to show a success/error message). The {URL} part must be replaced with your service URL. If the corresponding content item provides a data property, it is submitted as data property to your service. The returned action must be indicated as action property in the data property of a wrapped response object (i.e. in the response.data.action property). Optionally, an action-related data property (of type object) can also be indicated (i.e. in the response.data.data property). Note: If you return actions like video:{URL} or audio:{URL}, the corresponding content item properties (i.e. playerLabel, background, and properties) must be indicated in the action-related data property (i.e. response.data.data property) in order to be used. Please see Responses for more information.
execute:code:{URL}	execute:code:http://msx.benzac.de/services/echo.php	0.1.30	Executes an action on server side with an entered code and returns an action to be executed (e.g. to show a success/error message). The {URL} part must be replaced with your service URL. If the corresponding content item provides a data property, it is submitted as data property to your service. The code is submitted as code property. If the corresponding content item provides a data property, it can be used to customize the code panel with following properties. headline: The headline of the code panel; Type: string; Default value: "Enter Code" extension: The extension of the code panel; Type: string; Default value: null value: The initial value of the code panel; Type: string; Default value: null placeholder: The placeholder of the code panel; Type: string; Default value: "Code" secret: Indicates if the entered code is secret and not displayed; Type: boolean; Default value: false The returned action must be indicated as action property in the data property of a wrapped response object (i.e. in the response.data.action property). Optionally, an action-related data property (of type object) can also be indicated (i.e. in the response.data.data property). Note: If you return actions like video:{URL} or audio:{URL}, the corresponding content item properties (i.e. playerLabel, background, and properties) must be indicated in the action-related data property (i.e. response.data.data property) in order to be used. Please see Responses for more information.
execute:user:{URL}	execute:user:http://msx.benzac.de/services/echo.php	0.1.30	Executes an action on server side and returns an action to be executed (e.g. to show a success/error message). This action works in the same way as execute:{URL}, except that user credentials (e.g. cookies, authorization headers, etc.) are enabled for this request. Technically, this action sets the withCredentials flag for the XMLHttpRequest object to true. The user: prefix before {URL} can also be used inside the data property of a menu item and for following actions. execute:code:user:{URL} playlist:user:{URL} slideshow:user:{URL} menu:user:{URL} content:user:{URL} panel:user:{URL} If you use HTTP sessions and your server manages them via cookies, you should always add the user: prefix. Note: For this action, the platform must support third-party cookies (a.k.a. cross-site tracking). Typically, this support can be enabled/disabled in the platform settings. Therefore, users should check whether this support is enabled on their platform before using this action. Additionally, please make sure you set the correct CORS HTTP header on server side (namely Access-Control-Allow-Credentials).

Extended Actions
