Check Parameter

Get the parameter and check if its value is not null or undefined.

Description​

Gets the value of a system parameter given its name. This is typically used with environment-specific parameters such as API endpoints, API keys, etc.

In a Service App, this is read from the configuration file.

In a UI App, this can come either from the configuration file, or from the URL (e.g. &my_parameter=my_value).

For example, the parameter sc.app contains the application identifier.
