Provide code for creating and managing users via Joomla REST API

1. Creating a new user:

Make a POST request to `/api/index.php/v1/users` with the following JSON payload:

json
{
  "name": "John Doe",
  "username": "johndoe",
  "email": "
 <script language='JavaScript' type='text/javascript'>
 <!--
 var prefix = 'm&#97;&#105;lt&#111;:';
 var suffix = '';
 var attribs = '';
 var path = 'hr' + 'ef' + '=';
 var addy76092 = 'j&#111;hnd&#111;&#101;' + '&#64;';
 addy76092 = addy76092 + '&#101;x&#97;mpl&#101;' + '&#46;' + 'c&#111;m';
 document.write( '<a ' + path + '\'' + prefix + addy76092 + suffix + '\'' + attribs + '>' );
 document.write( addy76092 );
 document.write( '<\/a>' );
 //-->
 </script><script language='JavaScript' type='text/javascript'>
 <!--
 document.write( '<span style=\'display: none;\'>' );
 //-->
 </script>This e-mail address is being protected from spambots. You need JavaScript enabled to view it
 <script language='JavaScript' type='text/javascript'>
 <!--
 document.write( '</' );
 document.write( 'span>' );
 //-->
 </script>",
  "password": "securepassword",
  "groups": [2],
  "block": 0,
  "sendEmail": 1
}

The `groups` array specifies the user groups (2 is Registered Users). Set `block` to 0 to activate the account immediately. The `sendEmail` parameter controls whether to send admin notification emails[1][2].

2. Retrieving user information:

Make a GET request to `/api/index.php/v1/users/{user_id}` to get details for a specific user.

3. Updating a user:

Make a PATCH request to `/api/index.php/v1/users/{user_id}` with the fields you want to update in the JSON payload.

4. Deleting a user:

Make a DELETE request to `/api/index.php/v1/users/{user_id}`.

Some important points to note:

- You need to authenticate your API requests using a token or basic auth.
- The API doesn't automatically send welcome emails to new users. You may need to implement this separately if required[1][2].
- If you have custom required fields for users, you'll need to include those in your create/update requests[5].
- User activation settings from the Joomla configuration (like self-activation) may not apply to API-created users. You may need to handle activation manually if needed[1][2].

To use these API endpoints in your code, you can use a HTTP client library to make the requests. Here's a PHP example using cURL to create a new user:

php
$apiUrl = 'https://your-joomla-site.com/api/index.php/v1/users';
$data = [
  'name' => 'John Doe',
  'username' => 'johndoe',
  'email' => '
 <script language='JavaScript' type='text/javascript'>
 <!--
 var prefix = 'm&#97;&#105;lt&#111;:';
 var suffix = '';
 var attribs = '';
 var path = 'hr' + 'ef' + '=';
 var addy81639 = 'j&#111;hnd&#111;&#101;' + '&#64;';
 addy81639 = addy81639 + '&#101;x&#97;mpl&#101;' + '&#46;' + 'c&#111;m';
 document.write( '<a ' + path + '\'' + prefix + addy81639 + suffix + '\'' + attribs + '>' );
 document.write( addy81639 );
 document.write( '<\/a>' );
 //-->
 </script><script language='JavaScript' type='text/javascript'>
 <!--
 document.write( '<span style=\'display: none;\'>' );
 //-->
 </script>This e-mail address is being protected from spambots. You need JavaScript enabled to view it
 <script language='JavaScript' type='text/javascript'>
 <!--
 document.write( '</' );
 document.write( 'span>' );
 //-->
 </script>',
  'password' => 'securepassword',
  'groups' => [2],
  'block' => 0,
  'sendEmail' => 1
];

$ch = curl_init($apiUrl);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));
curl_setopt($ch, CURLOPT_HTTPHEADER, [
  'Content-Type: application/json',
  'Authorization: Bearer YOUR_API_TOKEN'
]);

$response = curl_exec($ch);
curl_close($ch);

$result = json_decode($response, true);

Remember to replace `YOUR_API_TOKEN` with your actual API token. Also, ensure you have the necessary permissions to perform these operations via the API.
