To retrieve Detailed Call History information, you must use a token with the spark-admin:calling_cdr_read scope. The authenticating user must be a read-only-admin or full-admin of the organization and have the administrator role "Webex Calling Detailed Call History API access" enabled.

Detailed Call History information is available 5 minutes after a call has ended and may be retrieved for up to 48 hours. For example, if a call ends at 9:46 am, the record for that call can be collected using the API from 9:51 am, and is available until 9:46 am two days later.

This API is rate-limited to one call every 1 minutes for a given organization ID.

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 then in the Webex Calling reports section see Calling Detailed Call History Report.

By default, the calls to analytics.webexapis.com are sent 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 response is returned. The body of the response in this case contains the end point information where a user can get data for the user's organization.
