Sort Definition
Many API endpoints support filtering and sorting of the data they return.
These endpoints usually, but not always, have a 'Search' word in their URI, like '/Consumers/Search'.
Building sort expression
Sort expressions are defined as JSON. It's defined as a collection of sort specs, for example:
Sort Expression
[  
  {  
     "Column":"Column1",
     "Direction":"ASC"
  },
  {  
     "Column":"Column2",
     "Direction":"DESC"
  }
]- ASC - sort in ascending order - the default if no direction is specified 
- DESC - sort in descending order.
