Attention developers, client_code field will be deprecated from Get Account's call history endpoint in June 2025. Plan ahead to avoid disruptions.

Zoom Phone client_code deprecation


Phone API updates ensure efficient and secure access to data. As part of these updates, we will deprecate the **client_code** field in the response body of the [/phone/call_history](/docs/api/phone/#tag/call-logs/GET/phone/call_history), in June 2025. 

Additionally, the [phone/call_history/\{callLogId\}/client_code](/docs/api/phone/#tag/call-logs/PATCH/phone/call_history/\{callLogId\}/client_code) will only support adding a user **client_code** and will not allow adding an admin log.

## Changed
- Deprecating the `client_code` response field in this Phone API:
    `GET /v2/phone/call_history`

- Restricting `client_code` assignment to user logs only this Phone API:
    `PATCH v2/phone/call_history/{callLogId}/client_code`
