The CDR Feed API is recommended for users who need to pull CDR records for a specific time period. For more up-to-date records, use the cdr_stream endpoint API instead.

To retrieve Detailed Call History information, your request must include a token with the spark-admin:calling_cdr_read scope. Additionally, the authenticating user must have the administrator role "Webex Calling Detailed Call History API access" enabled.

The CDR Feed API can query any 12-hour period between 5 minutes ago and 30 days prior to the current UTC time. Only 12 hours of records can be retrieved per request (i.e., the time between the selected start and end times in a single API call). For example: If a call ends at 9:46 AM, the record is available for collection starting at 9:51 AM and remains available until 9:46 AM 30 days later. The maximum query duration starting at 9:51 AM would end at 9:51 PM the same day.

This API is rate-limited to 1 initial request per minute per user token, with up to 10 additional pagination requests per minute per user token.

Details on the fields returned from this API and their potential values are available at https://help.webex.com/en-us/article/nmug598/Reports-for-Your-Cloud-Collaboration-Portfolio. Select the Report templates tab, and under the Webex Calling reports, see Calling Detailed Call History Report.

By default, the calls to analytics-calling.webexapis.com are routed to the closest region's servers. If the region's servers host the organization's data, then the data is returned. Otherwise, an HTTP 451 error code is returned. In such cases, the response body contains endpoint information indicating where the organization’s data can be retrieved.
