# Debug in-bound REST queries

You can debug in-bound REST queries by reviewing the session debug log.

When the **glide.rest.debug** property is **true**, all in-bound REST processing is logged in the session debug log.

REST logging includes processing durations, headers, and the request body. Prolonged use of this property can affect performance, so it is best to use it while debugging REST processing, and then set the property back to **false**.

**Note:** You may not see the resulting log statements if you are not on the application node that processed your REST request. In this case, please contact Technical Support.

You can include session debug logs in a REST response body by passing the X-WantSessionDebugMessages header in the request. For more information, see [Returning session debug logs in a REST response](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/api-reference/rest-api-explorer/rest-session-debug-header.md). To view debug logs, see [Display debugging logs](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/api-reference/scripts/c_SessionDebug.md).
