# Invalidate cache

The Invalidate cache action node clears cached response data on a service [endpoint](https://docs.appfarm.io/reference/services/service-endpoints). It is only available for [services](https://docs.appfarm.io/reference/services).

**Beta feature**

Beta features are almost finalized but minor changes may still occur.
{% endhint %}

## Usage

To use this action node, the endpoint must have the **Cache Response Data** property selected.

If the endpoint has query parameters, the response data is cached based on those parameters, potentially resulting in multiple caches. In this case the query parameter values must be specified to invalidate the specific cache.
