UMA API

UMA API Document#

User-Managed Access (UMA) is a profile of OAuth 2.0. UMA defines how resource owners can manipulate to protect the resources. The client can have access by arbitrary requesting parties, which means the requesting resource can be any number of resource servers and a centralized authorization server managing the access based on protected resource rules and policies defined.

In order to increase interoperable communication among the authorization server, resource server, and client, UMA leverages two purpose-built APIs related to the outsourcing of authorization, themselves protected by OAuth (or an OAuth-based authentication protocol) in embedded fashion.

The UMA protocol has three broad phases as below

                                          +--------------+
                                           |   resource   |

UMA Authorization API#

Overview#

PATH#

/requester/perm

requestRptPermissionAuthorization#

POST

/requester/perm

Client Requests Authorization Data Once in possession of a permission ticket and an AAT for this authorization server, the client asks the authorization server to give it authorization data corresponding to that permission ticket. It performs a POST on the RPT endpoint, supplying its own AAT in the header and a JSON object in the body with a "ticket" property containing the ticket as its value.

If the client had included an RPT in its failed access attempt, It MAY also provide that RPT in an "rpt" property in its request to the authorization server.

In circumstances where the client needs to provide requesting party claims to the authorization server, it MAY also include a "claim_tokens" property in its request; see Section 3.4.1.2.1 for more information. The authorization server uses the ticket to look up the details of the previously registered requested permission, maps the requested permission to operative resource owner policies based on the resource set identifier and scopes associated with it, potentially requests additional information, and ultimately responds positively or negatively to the request for authorization data.

The authorization server bases the issuing of authorization data on resource owner policies. These policies thus amount to an asynchronous OAuth authorization grant. The authorization server is also free to enable the resource owner to set policies that require the owner to interact with the server in near-real time to provide consent subsequent to an access attempt. All such processes are outside the scope of this specification.

UMA Resource Registration API#

/host/rsrc/resource_set

Overview#

Resource set is defined by the resource server, which is required by the authorization server to register the resource set description.

Resource set description is a JSON document with the following properties described in ResourceSet

RESTful API is used by Resource Server at the authorization server's resource set registration endpoint to create, read, update, and delete resource set description.

Request to the resource set is registration is incorrect, the authorization server responds with an with error message by including the below error codes in the response. Discussed detail in unsupported methods

unsupported_method_type: The resource server request used an unsupported HTTP method. The authorization server MUST respond with the HTTP 405 (Method Not Allowed) status code.
not_found: The resource set requested from the authorization server cannot be found. The authorization server MUST respond with HTTP 404 (Not Found) status code.

PATH#

/host/rsrc/resource_set{rsid}

DELETE /host/rsrc/resource_set{rsid}

Data Types#

ResourceSet #

Type	Required	Access	Description	Notes
string	required	name	A human-readable string describing a set of one or more resources. The authorization server MAY use this name in any user interface it presents to the resource owner.	-
string	optional	uri	A URI that provides the network location for the resource set being registered. For example, if the resource set corresponds to a digital photo, the value of this property could be an HTTP-based URI identifying the location of the photo on the web. The authorization server MAY use this information in various ways to inform clients about a resource set's location.	When a client attempts access to a presumptively protected resource without an access token, the resource server needs to ascertain the authorization server and resource set identifier associated with that resource without any context to guide it. In practice, this likely means that the URI reference used by the client needs to be unique per resource set.
string	optional	type	A string uniquely identifying the semantics of the resource set. For example, if the resource set consists of a single resource that is an identity claim that leverages standardized claim semantics for "verified email address", the value of this property could be an identifying URI for this claim. The authorization server MAY use this information in processing information about the resource set or displaying information about it in any user interface it presents to the resource owner.	-
Array[string]	required	scopes	An array of strings indicating the available scopes for this resource set. Any of the strings MAY be either a plain string or a URI	-
string	optional	icon_uri	A URI for a graphic icon representing the resource set. The authorization server MAY use the referenced icon in any user interface it presents to the resource owner.	-

Parameter	Required	Description	Data Type

Response#

Errors#

Status Code	Reason
405	Introspection of RPT is not allowed by GET HTTP method.

requestRptStatus#

POST /rpt/status

The resource server MUST determine a received RPT's status, including both whether it is active and, if so, its associated authorization data, before giving or refusing access to the client. An RPT is associated with a set of authorization data that governs whether the client is authorized for access.

The token's nature and format are dictated by its profile. The profile might allow it to be self-contained, such that the resource server is able to determine its status locally, or might require or allow the resource server to make a run-time introspection request of the authorization server that issued the token.

The endpoint MAY allow other parameters to provide further context to the query. For instance, an authorization service may need to know the IP address of the client accessing the protected resource in order to determine the appropriateness of the token being presented.

To prevent unauthorized token scanning attacks, the endpoint MUST also require some form of authorization to access this endpoint, such as client authentication as described in OAuth 2.0 [RFC6749] or a separate OAuth 2.0 access token such as the bearer token described in OAuth 2.0 Bearer Token Usage [RFC6750]. The methods of managing and validating these authentication credentials are out of scope of this specification.

URL#

http://gluu.org/rpt/status

Parameters#

form

Parameter	Required	Description	Data Type
token	true	The string value of the token. For access tokens, this is the "access_token" value returned from the token endpoint as defined in OAuth 2.0 [RFC6749] section 5.1. For refresh tokens, this is the "refresh_token" value returned from the token endpoint as defined in OAuth 2.0 [RFC6749] section 5.1. Other token types are outside the scope of this specification.	string
token_type_hint	false	A hint about the type of the token submitted for introspection. The protected resource MAY pass this parameter in order to help the authorization server to optimize the token lookup. If the server is unable to locate the token using the given hint, it MUST extend its search across all of its supported token types. An authorization server MAY ignore this parameter, particularly if it is able to detect the token type automatically. Values for this field are defined in OAuth Token Revocation [RFC7009].	string
