Revoking S3 access keys in WHMCS

You can revoke the specified access key pair of the specified user with the ostor-users service and the following parameters: emailAddress specifying the user email address, revokeKey specifying the access key in the key pair. WHMCS removes the key pair when you click Revoke Access Key. Create a file S3_revokeAccessKey.php with the following contents:

<?php

// Load configuration and libraries.
require('../../includes/staas_scripts/S3_delClientNote.php');
require('../../includes/staas_scripts/S3_getClient.php');
require('../../includes/staas_scripts/S3_getConfig.php');
require('../../includes/staas_scripts/S3_requestCurl.php');
require('../../init.php');

// Revoke s3 access key pair.
function S3_revokeAccessKey($userid) {

    // Load configuration.
    $s3_config = s3_getConfig();

    // Get whmcs user email.
    $s3_whmcs = S3_getClient($userid, $s3_config['whmcs_username']);

    // Get first s3 access key.
    $s3_client = S3_requestCurl(
        $s3_config['s3_key'],
        $s3_config['s3_secret'],
        $s3_config['s3_gateway'],
        "/?ostor-users&emailAddress=" . $s3_whmcs['email'],
        "GET"
    );

    // Revoke s3 access key.
    S3_requestCurl(
        $s3_config['s3_key'],
        $s3_config['s3_secret'],
        $s3_config['s3_gateway'],
            "/?ostor-users&emailAddress=" . $s3_whmcs['email'] .
            "&revokeKey=" . $s3_client['AWSAccessKeys']['0']['AWSAccessKeyId'],
        "POST"
    );

    // Delete note with the s3 access key and s3 secret.
    S3_delClientNote(
        $s3_whmcs['userid'],
        $s3_config['whmcs_username'],
        $s3_client['UserId'],
        $s3_client['AWSAccessKeys']['0']['AWSAccessKeyId']
    );

    // Redirect back.
    header('Location: ' . $_SERVER['HTTP_REFERER']);
}

// Call function.
S3_revokeAccessKey($_GET['userid']);
