12. ANNEX 4: NBI API Description
12.1. Introduction
OSM North Bound Interface is RESTful, following ETSI SOL005 standard. It admits both YAML/JSON formats.
By default, it serves https (auto-signed certificate) on port 9999. Bearer authentication (with token) is used. Basic authentication or no authentication is also possible changing nbi.cfg file.
For development purposes it admits web browser navigation using a basic http format.
12.2. Request headers
Accept: 'application/json','application/yaml' in most of the cases. Use ‘text/html’ for web navigation. Use 'text/plain','application/zip' for descriptor artifacts showing. This header field shall be present if the response is expected to have a non-empty message body.
Content-Type: 'application/json','application/yaml' for most of the cases. For packages uploading use 'application/gzip','application/zip','application/x-gzip','application/binary'. For descriptor artifacts it can be used 'text/plain'. This header field shall be present if the request has a non-empty message body.
Authorization: 'Bearer <token_id>'. The authorization token for the request. It is mandatory except when a token is requested.
Content-Range: '<first byte>-<last byte>0/<total>'. It allows uploading a descriptor by chunks.
Transaction-Id: '<id>'. When uploaded by chunk, the id returned by first chunk
Content-File-MD5: '<md5>'. MD5 of uploaded package.
Content-Filename: '<filename>'. Filename of the uploaded package.
Query-String-Format: '<yaml>'. Parses query string values using yaml format.
12.3. Response headers
Content-Type: 'application/json','application/yaml' is the more normal. 'text/html' when web navigation. 'application/gzip','text/plain' for descriptor artifacts
Location: '/<main_topic>/v1/<topic>/<id>'. Always that something is created, this header is present containing URL to this element.
WWW-Authenticate: 'Bearer realm="{}"'. When Authentication error is obtained.
**Retry-After**: ''. (Future releases)
12.4. RBAC
From Release SIX, operations are authorized via RBAC (Role Base Access Control). Each user and project is assigned with a set of roles, and some of them must grant the intended operation. If administrative query string is used (see next section), role must grant the use of it in addition to the operation.
Role permissions are organized in a hierarchical tree, separated by colon, optionally ending with the http operation. The value of False means not granted, meanwhile with True it is granted. If this permission is missing, the immediate hierarchical permission applies. When there is not hierarchical at all, the defined “default” permission applies, and if “default” is missing, not granted is assumed. See these examples initial roles; and role permissions for the list of RBAC permission with their operation. In following sections the RBAC permission granting this operation is indicated in brackets.
12.5. Query String
Query string has the format: '?key=value&key2=value2&...'.
For GET method it allows filtering with this format, follows SOL005 section 4.3.2:
query string := ?<simpleFilterExpr>["&"<simpleFilterExpr>]*
simpleFilterExpr := <attrName>["."<attrName>]*["."<op>]"="<value>[","<value>]*
op := "eq" | "neq" (or "ne") | "gt" | "lt" | "gte" | "lte" | "cont" | "ncont"
equal (by default), not equal, greater than, less than, greater than or equal, less than or equal, contains, not contains
attrName := string. For filtering inside array, use the index element of the array, or add ANYINDEX to apply the filtering over the same array element
For PUT/POST/PATCH It allows override e.g. package content, with the values of this query string
12.5.1. Administrative Query String
Some special keys used for administration are:
FORCE(=True)(rbac:force). Forces and operation. It disables descriptor checking, dependency checking. For delete, it allows deleting things that cannot done in normal operation because dependency. But beware that forcing deletion will not deletes created things at VIM level.PUBLIC(=True)(rbac:public). Allows getting public descriptor or instances (apart from those belonging to the project used login). For write/update operations, it used for set or unset a descriptor as publicADMIN(rbac:admin). Allows making operations on behalf of different project(s) than the one used for login (=projectA,projectB,...). Also to show all descriptor or instances (justADMIN). For update operations..SET_PROJECT=ProjectA,ProjectB,...(rbac:set_project). Allows adding an existing descriptor or instance to a project portfolio with an update operation.

12.14. VNFLCM Details
Since Release TWELVE, OSM supports the Or-Vnfm interface (SOL003) to allow life cycle operation of VNFs. With the support of [ETSI GS NFV-SOL003(https://www.etsi.org/deliver/etsi_gs/NFV-SOL/001_099/003/03.03.01_60/gs_NFV-SOL003v030301p.pdf) API, OSM enables the ability to serve as independent VNFM that can be integrated with any other Orchestrator and can perform VNF Life cycle management operations.
Besides the addition of VNF lifecycle API calls to instantiate, scale and terminate the NF, this feature is complemented with the capability to subscribe to those events and be notified, in the same way that it was already supported for NS lifecycle events.

/vnflcm/v1/vnf_instances. (rbac: vnflcm_instances)
GET: Obtain the list of VNF Instances
POST: Creates a VNF, but do not instantiate it. It returns the vnfInstanceId in the response header
'Location'. Example of request content:
vnfdId: vnfd-internal-id # mandatory
vnfInstanceName: instance-name # mandatory
vimAccountId: vim-id # mandatory
vnfInstanceDescription: instance-description
additionalParams:
constituent-cpd-id: connection-point-ref

virtual-link-profile-id: vld-name
/vnflcm/v1/vnf_instances/ID. (rbac: vnflcm_instances:id)
GET: Show details of a concrete VNF Instance
DELETE: Deletes a VNF. It fails if VNF is in ‘INSTANTIATED’ state
/vnflcm/v1/vnf_instances/ID/instantiate. (rbac: vnflcm_instances:id:instantiate:post)
POST: (Asynchronous). Deploys a VNF that it is in NOT_INSTANTIATED state. It returns the vnfLcmOpOccId (Operations Occurrence Id) in the response header
'Location'. Example of request content:
vnfName: instance-name # mandatory
vnfId: vnfd-id # mandatory
vimAccountId: vim-id # mandatory
vnfDescription: instance-description # mandatory
/vnflcm/v1/vnf_instances/ID/terminate. (rbac: vnflcm_instances:id:terminate:post)
POST: (Asynchronous). Undeploys a VNF that it is in INSTANTIATED state. It returns the vnfLcmOpOccId (Operations Occurrence Id) in the response header
'Location'. Example of request content:
terminationType: str
gracefulTerminationTimeout: int
/vnflcm/v1/vnf_instances/ID/scale. (rbac: vnflcm_instances:id:scale:post)
POST: (Asynchronous). Performs a manual scale OUT/IN of the VNF. It returns the vnfLcmOpOccId (Operations Occurence Id) in the response header
'Location'. Example of request content:
type: SCALE_OUT|SCALE_IN
aspectId: scaling-aspect-id
numberOfSteps: int
additionalParams:
member-vnf-index: member-vnf-index
/vnflcm/v1/vnf_instances/vnf_lcm_op_occs. (rbac: vnf_instances:opps)
GET: Obtain the list of VNF Instances operations
/vnflcm/v1/vnf_instances/vnf_lcm_op_occs/ID. (rbac: vnf_instances:opps:id)
GET: Show details of a concrete VNF Instance operation
12.14.2. VNFLCM Subscription and Notification support
/vnflcm/v1/subscriptions. (rbac: vnflcm_subscriptions)
GET: Obtain the list of subscriptions
POST: Creates a subscription. It returns the subscriptionId in the response header
'Location'. Example of request content:
Refer ETSI SOL003 document for filter options Page no 97
filter:
VnfInstanceSubscriptionFilter:
vnfdIds:
- hackfest_basic_metrics-vnf
notificationTypes:
- VnfLcmOperationOccurrenceNotification
operationTypes:

This payload implies that, for vnfd id hackfest_basic_metrics-vnf if operation state is PROCESSING and operation type is INSTANTIATE then, send a notification to http://webhook.site/82b1d459-dce8-4ed2-bda1-360049d23bc1 using the “authentication” mechanism whose payload is of datatype VnfLcmOperationOccurrenceNotification. Refer ETSI SOL003 document for notification reference Page no 102

/vnflcm/v1/subscriptions/ID. (rbac: vnflcm_subscriptions:id)
GET: Show details of a concrete VNF subscription
DELETE: Deletes a VNF subscription
