+    <title>Description</title>
+
+    <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 64-bit cookie in.</para>
+  </refsect1>
+
+  <refsect1>
+    <title>Return Value</title>
+
+    <para>On success, these calls return 0 or a positive integer. On failure, they return a negative
+    errno-style error code.</para>
+
+    <para>On success, the cookie/reply cookie is returned in the specified 64-bit unsigned integer
+    variable.</para>
+
+    <refsect2>
+      <title>Errors</title>
+
+      <para>Returned errors may indicate the following problems:</para>
+
+      <variablelist>
+        <varlistentry>
+          <term><constant>-EINVAL</constant></term>

+
+        <varlistentry>
+          <term><constant>-ENODATA</constant></term>
+
+          <listitem><para>No cookie has been assigned to this message.  This either indicates that the
+          message has not been sent yet and hence has no cookie assigned, or that the message is not a method
+          response message and hence carries a reply cookie field.</para></listitem>
