# Retrieve a Kafka Cluster User

Retrieves a specific user associated with a Kafka cluster, including access certificates in the metadata.

## Endpoint

`GET /clusters/{clusterId}/users/{userId}/access`

## Description

The `GET /clusters/{clusterId}/users/{userId}/access` endpoint retrieves a specific user identified by userId from the Kafka cluster identified by clusterId. The response includes detailed metadata about the user, including creation and modification timestamps, ownership information, and current operational state. Access credentials such as certificateAuthority, privateKey, and certificate are also provided to facilitate secure communication with the Kafka cluster. Use this endpoint to manage and obtain detailed information about users' credentials within your Kafka infrastructure.

## Parameters

* `clusterId` (string, path, required): The UUID of the Kafka cluster from which to retrieve the user.
  * Example: `/clusters/e69b22a5-8fee-56b1-b6fb-4a07e4205ead/users/{userId}/access`
* `userId` (string, path, required): The UUID of the user whose credentials and metadata are to be retrieved.
  * Example: `d11db12c-2625-5664-afd4-a3599731b5af`

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

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

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.ionos.com/cloud/~/revisions/AMiYziCllTKB2y2lmONY/data-analytics/kafka/api-howtos/fetch-user.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
