+    <title>Description</title>
+
+    <para><function>sd_bus_get_name_creds()</function> queries the credentials of the bus client
+    identified by <parameter>name</parameter>. The <parameter>mask</parameter> parameter is a combo of
+    <constant index='false'>SD_BUS_CREDS_*</constant> flags that indicate which credential info the caller is
+    interested in. See
+    <citerefentry><refentrytitle>sd_bus_creds_new_from_pid</refentrytitle><manvolnum>3</manvolnum></citerefentry>
+    for a list of possible flags. On success, <parameter>creds</parameter> contains a new
+    <structname>sd_bus_creds</structname> instance with the requested information. Ownership of this instance
+    belongs to the caller and it should be freed once no longer needed by calling
+    <citerefentry><refentrytitle>sd_bus_creds_unref</refentrytitle><manvolnum>3</manvolnum></citerefentry>.
+    </para>
+
+    <para><function>sd_bus_get_owner_creds()</function> queries the credentials of the creator of the given
+    bus. The <parameter>mask</parameter> and <parameter>creds</parameter> parameters behave the same as in
+    <function>sd_bus_get_name_creds()</function>.</para>
