+ConfigScaleIn
+-------------
+
+The ConfigScaleIn command is used to apply any actions on a VNF as part of a ScaleIn flow. Actions could include updating the VNF configuration or running a set of other tasks.
+
+The ConfigScaleIn action can have multiple APPC templates associated with it.  APPC retrieves the VfModuleModelName from A&AI (model.model-vers.model-name), which is used as the unique identifier to select the correct APPC template.
+APPC creates or updates VNFC records in A&AI for the newly instantiated VM’s.  The orchestration-status of the VNFC’s is set to CONFIGURED.
+
+This action is supported via the Netconf (limited to configuration changes), Chef, and Ansible protocols.

+ConfigScaleIn Response
+^^^^^^^^^^^^^^^^^^^^^^
+
+**Success:**
+
+ - A successful ConfigScaleIn returns a success status code 400 when completed.
+
+**Failure:**
+
+ - A failed ConfigScaleIn returns a failure code 401 and the failure message.
+ - If the ConfigScaleIn is successfully performed on the VNF but there is a failure to update A&AI inventory, an intermediate failure message with failure code 501 is returned prior to the final 400 success message.
