Services for Privatemsg module I am using privatemsg services module to create REST API of privatemsg using Services Module in Drupal 7.

If I send GET request to this url : http://example.com/rest/privatemsg/ I get all messages including messages in Inbox and Sent. Is there any way to Get messages from Inbox and Sent separately ? OR is there any way i can differentiate messages from Inbox and Sent ?
That resource has an optional type parameter, so you should be able to get away with requesting:

http://example.com/rest/privatemsg/?type=inbox

Or ?type=sent, etc
