title: BARC Quarter Calendar API
description: "Quarter Calendar information from the Office of the Registrar specifically for BARC mainframe\
\ retirement. This API is designed to return a quarter information specifically needed by BARC. This\
\ API allows for querying quarter information for BARC calculations other systems. It is different\
\ from the Public Academic Quarter Calendar API as it has specific logic based on what actiontype\
\ is passed in. \r\n\r\nThe BasicAuth header is a base64-encoded(ucsbNetId:password) combination.\
\ The ucsbNetId/password combination should be of a service account registered with the Campus Identity\
\ systems (ETS, the Campus LDAP). This ucsbNetId needs to be supplied to the Office of the Registrar\
\ as part of the approval process."
