Am trying to log in to Dropbox as a user using cURL and PHP.

```
$ch = curl_init(); 
$data = array(
    't'=>'hxdlvCcN7SKKcfKCvpEO8-s2',
    'lhs_type'=>'anywhere',
    'login_email'=>'myemail@mail.com',
    'password'=>'mypass',
    'login_submit'=>1,
    'remember_me'=>'on',
    'login_submit_dummy'=>'Sign in'
);

// set cURL options and execute
curl_setopt($ch, CURLOPT_URL, "https://www.dropbox.com/login?lhs_type=anywhere");  
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);  
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS,http_build_query($data));
$request_token_response = curl_exec($ch);       
var_dump($request_token_response );

```

I get 403 page with this text:

```
It seems you tried to do something we can't verify. Did you log into a different Dropbox account in a different window? Try clicking here to go back to the page you came from, or just go home.

```

What am I doing wrong?
