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.

Server Actions[edit]
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.). Since version 0.1.90, it is also possible to execute multiple server actions at the same time by using a service:
prefix (e.g. execute:service:{URL}
, execute:service:accurate:{URL}
, execute:service:user:accurate:{URL}
, etc.). However, to detect errors and avoid overloading, the maximum number of parallel service actions is limited to 128.

execute:{URL}

If you use HTTP sessions and your server manages them via cookies, you should always add the 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 |
