# cPanel API 2 Functions - MysqlFE::listusersindb

Warning:
The cPanel API 2 system is deprecated. We **strongly** recommend that you use [UAPI](/cpanel/introduction) instead of cPanel API 2.

## Description

This function lists MySQL® database users that are authorized to use a
database.

Warning:
We **strongly** recommend that you use [UAPI](/cpanel/introduction/) instead of cPanel API 2. However, no equivalent UAPI function exists.

Important:
When you disable the [*MySQL/MariaDB* role](https://docs.cpanel.net/knowledge-base/general-systems-administration/how-to-use-server-profiles/#roles) **and** remote MySQL is **not** already configured, the system **disables** this function.

# List database users.

### cPanel Tag System (deprecated)

Warnings:
- cPanel tags are **deprecated**. We **strongly** recommend that you **only** use the [LiveAPI](/guides/guide-to-the-liveapi-system) system to call the cPanel APIs. Examples are **only** present in order to help developers move from the old cPanel tag system to our [LiveAPI](/guides/guide-to-the-liveapi-system).
- cPanel API 2 calls that use cPanel tags vary in code syntax and in their output.
- For more information, read our [Deprecated cPanel Tag Usage](/cpanel-api-2/cpanel-api-2-deprecate-cpanel-tag-usage/) documentation.

Notes:

- You **must** URI-encode values.
- `username` represents your account-level username.

- For more information and additional output options, read our [Guide to cPanel API 2](/cpanel-api-2/) documentation or run the `cpapi2 --help` command.
