WCF-WebHttp Adapter

The WCF-WebHttp adapter gives you the ability to send messages to RESTful services through the WCF-WebHttp send adapter. With the receive location you can receive messages from a RESTful service. Through the send adapter you can do a GET request. This is widely used service operation when it comes to interacting with a RESTful service. Besides GET, there is DELETE, POST and PUT. With GET and DELETE operations you cannot send any payload. For POST and PUT request, the adapter uses the BizTalk message body part to the HTTP content/payload.

Note: Since BizTalk sends out message bodies with BizTalk Server 2013 beta you will need to remove the message body with a pipeline.
