Determines whether a specified principal is authorized to perform a specified action in a specified context. The response is either true (the action is authorized) or false (the action is not authorized).

An example of using relevant authorization context to create an authorization decision..

An authorization context where the permission field is required

Authorization Context Permission Required

The requested action and contextual details.

A true or false on whether an action is authorized for a user

Whether an action is authorized for a user

Always returned if the request is successful and the request's Accept header is application/vnd.sas.authorization.direct.decision+json. However, if the Accept header is application/json or application/vnd.sas.authorization.direct.decision+json, 200 is returned only if the request is successful and the decision is `true`.

Content-Type

Location

Always returned if the request is successful and the request's Accept header is text/plain

The request was invalid. Returned if the authorization context is invalid.

Returned if the request's Accept header is application/vnd.sas.authorization.decision+json or application/json and the request was completed successfully but the authorization decision is `false`.

Obtain an authorization decision

Contextual information about an action that a principal is attempting. Represented by media type application/vnd.sas.authorization.context+json.

Authorization Context

A description of the HTTP request that is associated with an authorization request.

Authorization Context Request

An authorization rule that does not have a known ID. The rule has not been saved or the ID is unavailable for some other reason. Compare with SavedAuthorizationRule.

Authorization Rule

The result of a bulk authorization request. For each type of link in the request (bulkLinks, parameterizedLinks) two arrays containing the granted and prohibited links will be returned.

Authorized Links

This is a base schema used to define paginated collections of resources. This base schema is extended by other schemas in APIs by adding an 'items' array property. These extensions define the application/vnd.sas.collection media type (version 2)

baseCollection

Contextual information about an action that a principal is attempting, including one or more links that should be authorized against a supplied permission. Represented by media type application/vnd.sas.authorization.bulk.context+json.
Note: Use of either bulkLinks or parameterizedLinks is required. Use of both is allowed.

Bulk Authorization Context

Capabilties provide an abstraction layer on top of authorization rules, providing the ability to associate users and groups with specific application capabilities, and perform license checks to ensure users are authorized to access various areas of the software

Capability

Capability Summary

Capability summary collection

Error

An explanation of access for one principal.

Explanation

A map of relative URI keys to an array of Explanation values. Each explanation in each array explains authorization decisions for one principal.

Explanations

Information about the source or cause of the result. Includes a list of applicable rules, indication of whether any of those rules has a condition, and whether the result is direct (a rule directly targets the defined object and is directly assigned to the defined principal).

Factor

An authorization explanation, using new additional rules that aren't yet persisted in the service

Hypothetical

Any authorization rule that can be referenced by a unique identifier. This can be a savedAuthorizationRule or an unsaved authorization rule that has a client-specified identifier.

Identifiable Authorization Rule

An explanation of access for one principal and permission.

Individual Explanation

A link to a related operation or resource.

Link

Zero or more links that are to related resources and actions.

Links

A name-value pair of the form (value: localizedValue).

Localized Value

A link to a related operation or resource with a map of parameter names to values for use in authorization evaluations.

ParameterizedLink

An explanation of access for one principal and permission. Includes explanations for permissions conveyed by containing objects.

Permission Explanation

A map of permissions to link arrays. The keys of this map are the permissions that the link values are authorized for.

Permissions to Links

A map of permissions to parameterized link arrays. The keys of this map are the permissions that the link values are authorized for.  During authorization of the link the parameters will be added to the list of parameters supplied on the context.  The parameters are used in authorization conditional expressions.  If there is a conflict the parameters specified for the link will override.

Permissions to Parameterized Links

Principal

A collection of saved authorization rules.

Resource Collection of Authorization Rules

Resource Collection of Localized Values

A collection of principals (users and/or groups).

Resource Collection of Principals

Resource Collection of Shares

Describes an action to be performed asynchronously on a rule.

Rule Action

Instructions for a set of actions to be performed asynchronously. Consists of a state that describes how the overall asynchronous job is performing and a set of actions to perform on defined rules.

Rule Job

An operation to be performed on the defined rule.

Rule Patch Operation

An authorization rule that has a known rule ID and has been persisted.

Saved Authorization Rule

Any share that can be referenced by a unique identifier and has been persisted.

Saved Share

Selection

A share that does not have a known ID or sharedBy value. The share has not been saved or the ID is unavailable for some other reason. Compare with SavedShare.

Share

An operation to be performed on the defined share.

Share Patch Operation

property values that specify how sharing is configured. sas.authorization.share.enabled determines whether sharing is enabled at all in the system while sas.authorization.share.reshare.enabled determines whether users are allowed to grant reshare permission on objects.

Share Properties

The response from a pre-flight validation request. For APIs which support validation, the client can run operations (typically on resources in the `/commons/validation`) with `application/vnd.sas.validation+json` as the requested response type (via the `Accept:` request header). The service will validate the request but not execute the request, and return this response to indicate if the request was valid at the time it was made.

Status	Meaning	Description
200	OK	Always returned if the request is successful and the request's Accept header is application/vnd.sas.authorization.direct.decision+json. However, if the Accept header is application/json or application/vnd.sas.authorization.direct.decision+json, 200 is returned only if the request is successful and the decision is `true`.	Headers	Schema
201	Created	Always returned if the request is successful and the request's Accept header is text/plain	Headers	Schema
400	Bad Request	The request was invalid. Returned if the authorization context is invalid.
403	Forbidden	Returned if the request's Accept header is application/vnd.sas.authorization.decision+json or application/json and the request was completed successfully but the authorization decision is `false`.		Schema

Request Body

Responses

Name	Type	Required	Description
request	Authorization Context Request	false	A description of the HTTP request that is associated with an authorization request.
principals	array [Principal]	false	The set of principals representing the actor performing the action.
permission	string	true	A type of access. Allowed values: addcreatedeletereadremovesecureupdate
parameters	object	false	A map of keys to objects that represent the parameters and return object of a method being invoked. This can be null or empty.
matchParams	boolean	false	Whether the authorization service should strictly match query parameters in this context against a rule. Default: false
eachNamed	object	false	Map of parameter names to a new name that should be used in rule condition evaluation for collections. For example, if a parameter being used for evaluation is a collection named 'items', then eachNamed can map 'items' to 'item' so that item in the collection can be evaluated independently against a rule that references the '#item' variable.
version	integer<int32>	false	The authorization context's media type version. The version described here is version 1.
