Invoking Functions with Complex Data Type Parameter

In OData functions, parameter aliases need to be used to represent structure type parameter values. The value for the alias must be specified as a separate query option using the name of the parameter alias.

Parameter Aliases

Parameter aliases MUST start with an @ character, and its value MUST be specified either as a URL literal (for primitive values) or as a JSON formatted OData object (for complex values, or collections of primitive or complex values).

For more details about parameter aliases, please follow the links below.
