You can now use the flatListOfFields parameter to retrieve a list of the fields in a case or flow action. With this parameter, you avoid parsing all the layout information for the Pega Digital Experience API, making it easier for you to see only what you need to build your user interface.

The following Pega Digital Experience APIs support the flatListOfFields parameter:

• GET /casetypes/{ID}
• GET /assignments/{ID}/actions/{actionID}
• GET /cases/{ID}/actions/{actionID}

Specify the level of detail that you need in the list by setting the parameter's values to Full or Basic. Full returns the full level of information, including the control format and modes. Basic returns basic information about the property, such as the type, reference, and value.

You can test the flatListOfFields parameter in the Parameters section of the Pega Digital Experience API, for example, GET /casetypes/{ID}, as shown in the following figure.
