+
+                <para><function>sd_bus_message_get_cookie()</function> returns
+                the transaction cookie of a message. The cookie
+                uniquely identifies a message within each bus peer,
+                but is not globally unique. It is assigned when a
+                message is sent.</para>
+
+                <para><function>sd_bus_message_get_reply_cookie()</function>
+                returns the transaction cookie of the message the
+                specified message is a response to. When a reply
+                message is generated for a method call message its
+                cookie is copied over into this field. Note that while
+                every message that is transferred is identified by a
+                cookie, only response messages carry a reply cookie
+                field.</para>
+
+                <para>Both functions take a message object as first
+                parameter and a place to store the 64bit cookie
+                in.</para>

+                <para>On success the cookie/reply cookie is returned
