• Reading Webex Calling CDRs through the API needs a token with the spark-admin:calling_cdr_read scope, and the administrator must hold the Webex Calling Detailed Call History API access role. in context
• As of December 2025, the Webex Calling cdr_feed endpoint can query any 12-hour period between 5 minutes and 30 days ago, returning at most 12 hours of records per request, selected on the record's Start Time. in context
• The Webex Calling cdr_stream endpoint can be called about one minute after a call ends, returns up to 2 hours of records per request, selects on the time the record was written to the database, and backfills late records automatically. in context
• The Webex Calling CDR APIs require the spark-admin:calling_cdr_read scope and the 'Webex Calling Detailed Call History API access' administrator role. in context
• For historical CDR reporting beyond 30 days, Cisco directs developers to the /v1/reports endpoint rather than the CDR Feed. in context
• The Webex Calling CDR Feed API (/v1/cdr_feed) can be queried from 5 minutes after a call ends, covers up to 30 days of data, and allows at most a 12-hour window per request, keyed on the call start time. in context
• The Webex Calling CDR APIs return between 500 and 5000 records per page. in context
• The CDR Stream API (/v1/cdr_stream) is Cisco's recommended primary API for continuous CDR consumption: it is keyed on database write time, queryable about 1 minute after a call, limited to a 2-hour window per request, retains 12 hours of data and backfills late records. in context
