Specifying pip dependencies
You can specify the Python modules that the platform installs during the app installation. See the following example for the format of this dictionary:
Configuration Section
In order to run an action, an app must operate on an asset that has been configured by the end user within . First, the platform must have one or more instances of an asset configured; at least one that is directly supported by the app, and that matches the vendor and product that the app supports.
README file
An app author can bundle a readme.html file in the app directory, which the platform renders as part of the app documentation. It is rendered between the app description and the asset configuration parameters.
Place Holder Data Type
The order key allows an app author to specify the order in which the controls are displayed to the user. In order to insert a blank, no control, at a specific location use the ph data_type with the order key. For example, to display a blank space between the first and second control define the configuration as shown in the following example:
Actions Section
The actions key defines an array of actions that this app supports. This exposes the core functionality that the app makes available to .
