-(Example of changing config TBD)
+The edit function of the Configs API is a little quirky at the Moment. Its format deviates from the usual edit flow of other APIs. This will be fixed, eventually. For now, to change the "Value" of ZM_X10_HOUSE_CODE from A to B:
+
+::
+
+    curl -XPUT http://server/zm/api/configs/edit/ZM_X10_HOUSE_CODE.json  -d "Config[Value]=B"
+
+To validate changes have been made:
+
+::
+
+    curl -XGET http://server/zm/api/configs/view/ZM_X10_HOUSE_CODE.json
