request_api_key_filter #

Description #

When Elasticsearch conducts authentication through API keys, the request_api_key_filter is used to filter requests based on request API ID.

Configuration Example #

A simple example is as follows:

flow:
  - name: test
    filter:
      - request_api_key_filter:
          message: "Request filtered!"
          exclude:
            - VuaCfGcBCdbkQm-e5aOx

The above example shows that requests from VuaCfGcBCdbkQm-e5aOx will be rejected. See the following information.
