You can examine the list of items in a catalog to find items of interest based on the values of their name and type attributes. You must retrieve a catalog item to get a Description and a usable reference to the underlying object.

Every vApp template or media image that is added to the catalog is represented as a CatalogItem element. When a client browses a catalog, it can read only the name, type, and href of each CatalogItem. To retrieve an item from the catalog, the client requires more information. In Example: Retrieve a Catalog Item, the client makes a GET request to the URL in the value of the href attribute of a CatalogItem. The response provides more information, including a description of the referenced object and another URL that the client can use to retrieve a representation of the object.

Prerequisites

This operation requires the rights included in the predefined vApp Author role or an equivalent set of rights.

Procedure
1

Retrieve the representation of a catalog in your organization.

Use a request like this one: 

GET https://vcloud.example.com/api/catalog/32
2

Examine the response to find the CatalogItem elements that the catalog contains.

The value of the name attribute of a CatalogItem element is taken from the name attribute of the referenced object. You can use it as a preliminary indicator of what the item represents.

Use a GET request of the form shown in the request portion of Example: Retrieve a Catalog Item.
