+Service Instantiation via ONAP NBI API (TM Forum)
+=================================================
+
+ONAP NBI allow you to use a TM Forum standardized API (serviceOrder API)
+
+Additional info in:

+   NBI Guide <../../../../../submodules/externalapi/nbi.git/docs/offeredapis/offeredapis.rst>
+
+
+ONAP NBI will convert that request to ONAP SO request.
+
+
+ServiceOrder management in NBI will support 2 modes:
+
+* E2E integration - NBI calls SO API to perform an End-To-end integration
+* Service-level only integration - NBI will trigger only SO request at
+  serviceInstance level (not at VNF, not at Vf-module level and nothing will
+  be created on cloud platform)
+
+ONAP SO prerequisite: SO must be able to find a BPMN to process service
+fulfillment (integrate VNF, VNF activation in SDNC, VF module)
+
+The choice of the mode is done by NBI depending on information retrieved
+in SDC. If the serviceSpecification is within a Category "E2E Service" ,
+NBI will use E2E SO API, if not only API at service instance level
+will be used.
+
+There is no difference or specific expectation in the service order API
+used by NBI user.
+
+
+Example of serviceOrder to instantiate (=add) a service based on model
+with id=0d463b0c-e559-4def-8d7b-df64cfbd3159
+
+
+::
+
+  curl -X POST \
+    http://nbi.api.simpledemo.onap.org:30274/nbi/api/v4/serviceOrder \
+    -H 'Accept: application/json' \
+    -H 'Content-Type: application/json' \
+    -H 'cache-control: no-cache' \
+    -d '{
+    "externalId": "BSS_order_001",
+    "priority": "1",
+    "description": "this is a service order to instantiate a service",
+    "category": "Consumer",
+    "requestedStartDate": "",
+    "requestedCompletionDate": "",
+    "relatedParty": [
+      {
+        "id": "JohnDoe",
+        "role": "ONAPcustomer",
+        "name": "JohnDoe"
+      }
+    ],
+    "orderItem": [
+      {
+        "id": "1",
+        "action": "add",
+        "service": {
+          "name": "my_service_model_instance_01",
+          "serviceState": "active",
+          "serviceSpecification": {
+            "id": "0d463b0c-e559-4def-8d7b-df64cfbd3159"
+          }
+        }
+      }
+    ]
+  }'
+
+In the response, you will obtain the serviceOrderId value.
+
+Then you have the possibility to check about the serviceorder
+(here after the serviceOrderId=5d06309da0e46400017b1123).
+
+This will allow you to get the serviceOrder Status (completed, failed...)
