You can open APM and use two simple ways to identify the metadata for classes that you wish to return in queries. In the first example, view the member names of items in a table. In the second, view the metadata for a specific field in a window.

To view all of the member names (attributes) of items in a table configuration:

1. In the Site window, navigate to the list of items. For example, select the Assets view and the Listing The tab displays the table configuration “Asset listing, by asset number”.

2. Click the Configuration list and then Open. The Configuration window appears.

3. Scroll to the right to see the Member Name column. Member name is the correct value to use to identify an attribute, for example, AssetNumber.

To view the metadata for a field:

1. In the Site window, open the object. For example, select the Assets view and the Listing Double-click an asset to open the Asset window.

2. Press Ctrl + Shift and then click the field you wish to see, for example, Classification:

3. The Control Properties window appears. Note the Entity set name and the Member name:

When creating the query in Postman, you would enter the following to return assets and their classifications:
