You can make resource method public by using setResourceAccess access as $this->setResourceAccess('users', 'public', 'post') Here first param in your plugin name, second is status and last is method, which is you want to make public. Means, it does not need authentication when called.

jimport('joomla.plugin.plugin');
//class structure example//ex - class plgAPIUsers extends ApiPluginclass plgAPIYour_plugin_name extends ApiPlugin
{
publicfunction__construct(&$subject, $config = array())
{
parent::__construct($subject, $config = array());
ApiResource::addIncludePath(dirname(__FILE__).'/users');
/*load language file for plugin frontend*/$lang = JFactory::getLanguage(); $lang->load('plg_api_your_plugin_name', JPATH_ADMINISTRATOR,'',true);
// Set the login resource to be public$this->setResourceAccess('your_plugin_name', 'public', 'post');
}
}

Create resource file login.php file

All resource file are placed in plugin resource folder.

<?php//class structure example//ex - class UsersApiResourceLogin extends ApiResourceclass Plugin_nameApiResourceResource_file_name extends ApiResource
{
publicfunctionget()
{
// Add your code here$this->plugin->setResponse( $result );
}
publicfunctionpost()
{
// Add your code here$this->plugin->setResponse( $result );
}
}
