To get Apiv2 authorization code without login page

Hi Nav

I think you should use Session Key Authentication

Please See the doc :

https://community.lithium.com/t5/Developer-Documentation/bd-p/dev-doc-portal?section=sessionauth

Using this you can authorise the user by making this below call.

curl -XPOST 'https://yourcommunity.com/restapi/vc/authentication/sessions/login?user.login=<login>&user.password=<password>'

If you follow OAuth 2.0 implementation, authorise will be done on Lithium End only.

If the user successfully logged in then it will redirect to the mention redirection Url along with auth code.Which can be used for further Api Call.

Hi HiteshKumar,

Thanks. You are right. The same I have implemented as below

	$username = 'xxxx';
	$password = 'xxxxx';
	//Get session key from lithium
	$login_fields = array(
		'user.login' => $username,
		'user.password' => $password,
		'xslt' => 'json.xsl',
		);
	$response = drupal_http_request('http://community.xxxx.co.uk/restapi/vc/authentication/sessions/login', array(
		'data' =>  drupal_http_build_query($login_fields),
		'method' => 'POST',
		'headers' => array('Content-Type' => 'application/x-www-form-urlencoded'),
	)

and passed restapi.session_key id along with actual request.

I received what I wanted now. :) 

Thanks.
