Request Headers

The following table describes required and optional request headers. In addition to the listed properties, the header can contain custom properties. See the example.

Request Header Description
Authorization Specify one of the following token values:
  • Azure Active Directory (Azure AD) JSON Web Token (JWT) token.
    Example: Authorization: Bearer <Azure AD JWT token>.
    For information on generating an Azure AD token, see Authenticate from an application.
  • A SAS token.
    Example: Authorization: SharedAccessSignature sr=<NAMESPACE NAME>.servicebus.windows.net&sig=<SHARED ACCESS KEY>&se=<TOKEN EXPIRY INSTANT>&skn=<SHARED KEY NAME>.
    For information on generating a SAS token, see Generate a Shared Access Signature token and Generate SAS token.
Content-Type Set to application/atom+xml;type=entry;charset=utf-8.
BrokerProperties JSON-encoded set of BrokeredMessage properties.
x-ms-retrypolicy (Optional) Set to NoRetry to disable automatic retry on send operations when transient errors occur.

Request Body

The request body is the message payload.

If the message is to be received via a protocol other than HTTP/HTTPS, the message body must be serialized; for example, with an XML System.Runtime.Serialization.DataContractSerializer. For example:

MemoryStream ms = new MemoryStream();  
DataContractSerializer serializer = new DataContractSerializer(typeof(string));  
serializer.WriteObject(ms, "This is a message.");  
byte[] body = ms7.ToArray();  

The preceding code produces the following message body:

<string xmlns="http://schemas.microsoft.com/2003/10/Serialization/">This is a message.</string>  

You can receive and process the message with the following code:

BrokeredMessage message = queueClient.Receive();  
string body = message.GetBody<string>(new DataContractSerializer(typeof(string)));  

Response

The response includes an HTTP status code and a set of response headers.
