BizTalk World

We gets following exception when BizTalk consume REST service which doesn’t require parameter or message body. But BizTalk always sends some message.

Error: A message sent to adapter “WCF-WebHttp” on send port with URI is suspended.

Error details: System.Net.ProtocolViolationException: Cannot send a content-body with this verb-type.

Solution:

Sometime when there is requirement in BizTalk to consume REST service with GET or DELETE method without parameters (when there is no parameter require in web URL) and without message. In this scenario we need to add method Name Suppress Body for Verbs in Messages section of send port WCF-WebHttp configuration as below.

Through setting this property BizTalk removes the message body from the REST service request.

Please refer here for more details about how to consume REST Service from BizTalk

In the Messages tab, specify how the message is sent to the REST interface.

Properties	Description
Outbound HTTP Headers	Specifies the HTTP headers that are stamped on the response message, if any.
Suppress Body for Verbs	Based on the verb you use to invoke a REST endpoint, you may or may not require a message payload. For example, you may not need a message payload while using the GET or DELETE verbs. However, to trigger a call to the REST endpoint using the send port, you may use a dummy message that includes a message payload. Before the message is sent to the REST endpoint, the message payload from the dummy message must be removed. You can specify the verbs for which the message payload must be removed using the Suppress Body for Verbs property. For example, if you want to remove the message payload while using a GET verb, specify the value for this property as GET.
