# Summary Representations

When you fetch a list of resources, the response includes a subset of the attributes for that resource. This is the “summary” representation of the resource. Some attributes are computationally expensive for the API to provide. For performance reasons, the summary representation excludes those attributes. To obtain those attributes, fetch the “detailed” representation.
