`removeFeatures`	Remove information about a manually installed feature.
`getAllFeatures`	Get a collection of feature descriptions in all available languages.
`getSupportedVersions`	Get a list of supported API versions.
`enableFeature`	Show the option to enable/disable a feature.
`disableFeature`	Remove the option to enable/disable a feature.

Model

The Api consists of a CGI which should be called using the HTTP/HTTPS Post method, and with JSON formatted data as input. The CGI includes a number of methods which gives the user the ability to:

Get a list of supported languages and locales.
Get information about available features in a given (supported) locale.
Add information about a manually installed feature.
List manually added features.
Remove information about a manually installed feature.
Get information about available features in all supported languages.
Get a list of supported API versions.

An API call includes the requested method along with any required input parameters.

Prerequisites

Property: Properties.PackageManager.PackageManager=yes
Property: Properties.AddOnFramework.Version=1.0 or higher
Firmware: 7.10 and later
Product category: Axis Cameras with application-support

Application Identification

The status method in the axis/addon.cgi lists axis-onscreencontrols as active.

Common examples

Languages

Use this example to check if feature descriptions can be displayed in a certain language.

1. Query for supported languages.

{
  "apiVersion": "1.0",
  "context": "",
  "method": "languages",
  "params": {
  }
}

2. Parse the JSON response.

Successful response

{
  "apiVersion": "1.0",
  "context": "",
  "method": "languages",
  "data": {
    "languages": [
      {
        "language": "English",
        "locale": "en-us"
      },
      {

        "locale": "de-de"
      }
    ]
  }
}

API reference

See Languages for further instructions.

Features

Get a list of features that support the English language

Use this example to access and list the camera’s unique features, all of which supports the English language.

1. Get a list of all the pre- and post installed features from the Camera that are available in the locale language English (en-us).

Get a list of features that support the Swedish language

Use this example to list features that supports the locale language “Svenska” (sv-sv). If there are no feature descriptions (default or added by user) available in Swedish, the response will contain an error. This means that the requested language should be one of the languages given in the response of Languages. If a feature is lacking a description in the requested language, the default (en-us) version for that feature will be included in the response.
