# Upcoming deprecations of Call Log APIs and Zoom Phone client_code fields

<!-- WARNING: THIS FILE WAS AUTOGENERATED! DO NOT EDIT! -->

Phone API and webhook updates maintain efficient and secure access to data. To that end, we'll deprecate several Call Log APIs and webhooks and replace them with new Call History APIs and webhooks on November 30, 2025.

Migrating to the new APIs and webhooks is an essential step to maintain your application's functionality and security. The new APIs and webhooks offer the same functions as the deprecated ones, with updates that streamline operations, increase security, and provide real-time accuracy in call log and call history data handling.

Test the new interfaces as early as possible to make the transition as seamless as possible.

Below shows the deprecated APIs and webhooks and their replacements.

### New APIs

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/%7BcallLogId%7D/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`
