# Deleting individual client identifiers

You can delete active client identifiers.

## About this task

The application programming interface (API) *(tooltip: \<div class="paragraph">
\<p>A specification of interactions available for building software to access an application or service.\</p>
\</div>)* requires only the message body with a client identifier in their respective sections, to delete active client identifiers. The API checks if the client identifier is present in the blocklist or not before deleting. If you provide a client identifier which is not part of the blocklist, the API ignores such client identifiers.

## Steps

* Use the attacklist API with PUT method to delete the client identifiers:

  * `URL: /v4/abs/attacklist`

  * `Method: PUT`

    |   |                                                                                                                                                                                                                                                                                       |
    | - | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
    |   | You can provide only specific section of a client identifier in the message body. For example, if you only want to delete specific usernames, then provide only the username section in the message body. Make sure that the `JavaScript Object Notation (JSON)` file is well-formed. |

    ### Example:

    The following is a sample message body for the attacklist API to delete client identifiers:

    ```json
    {
            "ips": [
                "192.168.4.10",
                "10.10.10.73",
                "10.1.1.4",
                "10.9.8.7"
            ],
            "cookies": {
                "PHPSESSIONID": [
                "Cookie1",
                "Cookie2"
                ],
            "JSESSIONID": [
                "Cookie3",
                "AnyCookie",
                "Cookie4"

            },
            "oauth_tokens": [
                "Token1",
                "Token2",
                "Token3"
            ],
            "api_keys": [
                "type2_api_key",
                "api_key_1",
                "api_key_2",
             ],
            "usernames": [
                "username1",
                "username2",
                "username3",
             ]
    }
    ```

    The following is a sample message body showing the client identifiers that were deleted:

    ```json
    {
      "message": "Success: The following attacks have been removed:",
      "date": "Thu Jun 09 03:39:12 UTC 2019",
      "attacklist": {
        "ips": [
                "192.168.4.10",
                "10.10.10.73",
                "10.1.1.4",
                "10.9.8.7"
        ],
        "cookies": {
          "PHPSESSIONID": [
                "Cookie1",
                "Cookie2"
          ],
          "JSESSIONID": [
                "Cookie3",
                "AnyCookie",
                "Cookie4"
          ]
        },
        "oauth_tokens": [
                "Token1",
                "Token2",
                "Token3"
        ],
        "api_keys": [
                "type2_api_key",
                "api_key_1",
                "api_key_2",
        ],
        "usernames": [
                "username1",
                "username2",
                "username3",
        ]
      }
    }
    ```
