+### CDP Monolog channel
+
+CDP Monolog channel handles webhook logs for easier separation of logs.
+
+```bash
+- { name: monolog.logger, channel: ibexa.cdp.webhook }
+```
+
+It's possible to configure `ibexa.cdp.webhook` Monolog channel to direct all logs to specific stream, file, or service.
+This allows webhook logs to be stored separately from the main application logs for easier debugging and analysis.
+
+To do it, in `config/packages/monolog.yaml` file, define a new handler for the `ibexa.cdp.webhook` channel that directs CPD Webhook events to a separate file.
+It can be configured in both `dev` and `prod` environments, for example:
+
+```yaml
+monolog:
+     handlers:
+        cdp_webhook:
+            type: stream
+            path: "%kernel.logs_dir%/cdp_webhook_%kernel.environment%.log"
+            level: debug
+            channels: [ 'ibexa.cdp.webhook' ]
+```
+
+If you want to avoid redundant or duplicate entries in the other logs, exclude the webhook channel by:
+
+```yaml
+channels: ["!ibexa.cdp.webhook"]
+```
