# Invalidate cache

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

{% hint style="warning" %}
**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.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.appfarm.io/library/action-nodes/invalidate-cache.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
