# Overview
The gateway cache function is used to query the published interface information cached locally by the FizzGate integration platform instance. You can quickly understand all the interfaces in effect for the current gateway instance. At the same time, you can check whether the published version number of the background interface is consistent with the interface version number cached locally by the gateway instance. To troubleshoot interface cache issues, the following describes the operation of the gateway cache function.
