How to create test_endpoint? I am new to drupal and I am  using  services module for using REST   and  RESTWS module. I used RESTWS and could get the content of the node by  http://base_url/node/1.xml and now I need to add a node and users from my external PHP application in to  drupal. I googled and I found here that we need to use http://base_drupal_url/drupal7/test_endpoint/users . I tried to create a service from Drupal 7, but I dont know what should I give on endpoint title ,name and endpoint path and I assume I need to give the same endpoint path in the curl.

Any help as to how to check if rest server is installed and how to create endpoint path would be of great help.

I am using Drupal 7 with services  module services-7.x-3.0-rc3
Services module is easy to use, but it can be tricky to configure especially if you are new to the concept. So,  I am going to post the screenshots to make configuration of Services modules easy for "Drupal Answers" users.

Following is the version of Services module installed on my machine:



Create an endpoint called 'rest' as shown below:



Select the type of server and endpoint path:



Select the list of resources that you want to enable and specify aliases:



Select the response formatters and request parsers that you want to enable:



You can test your configuration as shown below:



You can get the list of all nodes as below:



And specific node as:



Following are the excellent examples scripts provided by MichaelCole here http://drupal.org/node/910598#comment-4677738 to create nodes from any external PHP application. 

I am duplicating his code for completeness of this answer.

//--------------login to the server------------------------
$service_url = 'http://example.dev/rest/user/login.xml'; // .xml asks for xml data in response
$post_data = array(
    'username' =&gt; 'test',
    'password' =&gt; 'test',
);
$post_data = http_build_query($post_data, '', '&amp;'); // Format post data as application/x-www-form-urlencoded
// set up the request
$curl = curl_init($service_url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);  // have curl_exec return a string

curl_setopt($curl, CURLOPT_POST, true);             // do a POST
curl_setopt($curl, CURLOPT_POSTFIELDS, $post_data); // POST this data
// make the request
curl_setopt($curl, CURLOPT_VERBOSE, true); // output to command line
$response = curl_exec($curl);
curl_close($curl);
print "LOGIN RESPONSE:\n";
var_dump($response);



// parse the response
$xml = new SimpleXMLElement($response);
$session_cookie = $xml-&gt;session_name . '=' . $xml-&gt;sessid;
// print "SESSION_COOKIE: $session_cookie";

file_put_contents('session_cookie.txt', $session_cookie);

//----------------create a node -------------------------------
