VMware Cloud Director OpenAPI

VMware Cloud Director OpenAPI is a new API that is defined using the OpenAPI standards.
This ReSTful API borrows some elements of the legacy VMware Cloud Director API and establishes new patterns for use as described below.

Authentication

Authentication and Authorization schemes are the same as those for the legacy APIs. You can authenticate using the JWT token via the Authorization header or specifying a session using x-vcloud-authorization (The latter form is deprecated).

Operation Patterns

This API follows the following general guidelines to establish a consistent CRUD pattern:

Operation	Description	Response Code	Response Content
GET /items	Returns a paginated list of items	200	Response will include Navigational links to the items in the list.
POST /items	Returns newly created item	201	Content-Location header links to the newly created item
GET /items/urn	Returns an individual item	200	A single item using same data type as that included in list above
PUT /items/urn	Updates an individual item	200	Updated view of the item is returned
DELETE /items/urn	Deletes the item	204	No content is returned.

Asynchronous operations

Asynchronous operations are determined by the server. In those cases, instead of responding as described above, the server responds with an HTTP Response code 202 and an empty body. The tracking task (which is the same task as all legacy API operations use) is linked via the URI provided in the Location header.
All API calls can choose to service a request asynchronously or synchronously as determined by the server upon interpreting the request. Operations that choose to exhibit this dual behavior will have both options documented by specifying both response code(s) below. The caller must be prepared to handle responses to such API calls by inspecting the HTTP Response code.

Error Conditions

All operations report errors using the following error reporting rules:

• 400: Bad Request - In event of bad request due to incorrect data or other user error
• 401: Bad Request - If user is unauthenticated or their session has expired
• 403: Forbidden - If the user is not authorized or the entity does not exist

OpenAPI Design Concepts and Principles

• IDs are full Uniform Resource Names (URNs).
• OpenAPI's Content-Type is always application/json
• REST links are in the Link header.
• Multiple relationships for any link are represented by multiple values in a space-separated list.
• Links have a custom VMware Cloud Director-specific "model" attribute that hints at the applicable data type for the links.
• title + rel + model attributes evaluates to a unique link.
• Links follow Hypermedia as the Engine of Application State (HATEOAS) principles. Links are present if certain operations are present and permitted for the user"s current role and the state of the referred entities.
• APIs follow a flat structure relying on cross-referencing other entities instead of the navigational style used by the legacy VMware Cloud Director APIs.
• Most endpoints that return a list support filtering and sorting similar to the query service in the legacy VMware Cloud Director APIs.
• Accept header must be included to specify the API version for the request similar to calls to existing legacy VMware Cloud Director APIs.
• Each feature has a version in the path element present in its URL.
  Note API URL's without a version in their paths must be considered experimental.
