SessionAttr.exists - REST API

Overview

Returns a boolean flag or flags to indicate, respectively, if an input attribute or attributes exist for a session.

If only the very existence of attributes needs to be checked, it is faster and less resource-extensive to invoke this endpoint than using get.

While the call's Python equivalent has two versions, one for individual and the other for multiple attributes, with REST there is a single endpoint to cover both cases. Yet, just like in the Python call, it is more efficient to check multiple attributes in one REST call instead of repeatedly checking multiple attributes.

HTTP method: GET
URL path: /zato/sso/session/attr/exists
