Astakos API¶

This is Astakos API guide.

Overview¶

Astakos service co-ordinates the access to resources (and the subsequent permission model) and acts as the single point of registry and entry to the GRNET cloud services.

This document’s goals is to describe the APIs to the outer world. Make sure you have read the Identity Management Service (Astakos) general architecture first.

User API Operations¶

The operations described in this chapter allow users to send feedback and get user uuid/displayname mappings.

All the operations require a valid user token.

Send feedback¶

Post user feedback.

Uri	Method	Description
`/account/v1.0/feedback`	POST	Send feedback

Request Header Name	Value
X-Auth-Token	User authentication token

Request Parameter Name	Value
feedback_msg	Feedback message
feedback_data	Additional information about service client status

Return Code	Description
200 (OK)	The request succeeded
502 (Bad Gateway)	Send feedback failure
400 (Bad Request)	Method not allowed or invalid message data
401 (Unauthorized)	Missing or expired user token
500 (Internal Server Error)	The request cannot be completed because of an internal error

Get User catalogs¶

Return a json formatted dictionary containing information about a specific user

Uri	Method	Description
`/account/v1.0/user_catalogs`	POST	Get 2 catalogs containing uuid to displayname mapping and the opposite

Request Header Name	Value
X-Auth-Token	User authentication token

The request body is a json formatted dictionary containing a list with uuids and another list of displaynames to translate.

Example request content:

{"displaynames": ["user1@example.com", "user2@example.com"],
 "uuids":["ff53baa9-c025-4d56-a6e3-963db0438830", "a9dc21d2-bcb2-4104-9a9e-402b7c70d6d8"]}

Example reply:

{"displayname_catalog": {"user1@example.com": "a9dc21d2-bcb2-4104-9a9e-402b7c70d6d8",
                         "user2@example.com": "816351c7-7405-4f26-a968-6380cf47ba1f"},
'uuid_catalog': {"a9dc21d2-bcb2-4104-9a9e-402b7c70d6d8": "user1@example.com",
                 "ff53baa9-c025-4d56-a6e3-963db0438830": "user2@example.com"}}

Return Code	Description
200 (OK)	The request succeeded
400 (Bad Request)	Method not allowed or request body is not json formatted
401 (Unauthorized)	Missing or expired or invalid user token
500 (Internal Server Error)	The request cannot be completed because of an internal error

Service API Operations¶

The operations described in this chapter allow services to get user uuid/displayname mappings.

All the operations require a valid service token.

Get User catalogs¶

Return a json formatted dictionary containing information about a specific user

Uri	Method	Description
`/account/v1.0/service/user_catalogs`	POST	Get 2 catalogs containing uuid to displayname mapping and the opposite

Request Header Name	Value
X-Auth-Token	Service authentication token

The request body is a json formatted dictionary containing a list with uuids and another list of displaynames to translate. If instead of list null is passed then the response contains the information for all the system users (For discretion purposes this behavior is not exposed in the respective call of the User API).

Example request content:

{"displaynames": ["user1@example.com", "user2@example.com"],
 "uuids":["ff53baa9-c025-4d56-a6e3-963db0438830", "a9dc21d2-bcb2-4104-9a9e-402b7c70d6d8"]}

Example reply:

{"displayname_catalog": {"user1@example.com": "a9dc21d2-bcb2-4104-9a9e-402b7c70d6d8",
                         "user2@example.com": "816351c7-7405-4f26-a968-6380cf47ba1f"},
'uuid_catalog': {"a9dc21d2-bcb2-4104-9a9e-402b7c70d6d8": "user1@example.com",
                 "ff53baa9-c025-4d56-a6e3-963db0438830": "user2@example.com"}}

Return Code	Description
200 (OK)	The request succeeded
400 (Bad Request)	Method not allowed or request body is not json formatted
401 (Unauthorized)	Missing or expired or invalid service token
500 (Internal Server Error)	The request cannot be completed because of an internal error

Tokens API Operations¶

Authenticate¶

This call takes the user token or the user uuid/token pair, authenticates the user and returns information about the token, its holder as well as a list of services the user can access. If no request body is provided (the request content length is missing or equals to 0), the call operates in public mode, attempts no authentication and returns only the service catalog.

Uri	Method	Description
`/identity/v2.0/tokens`	POST	Checks whether the provided token is valid and conforms with the provided uuid (if present) and returns back information about the user

The input should be json formatted.

Example request:

{
    "auth":{
        "token":{
            "id":"CDEe2k0T/HdiJWBMMbHyOA"
        },
        "tenantName":"c18088be-16b1-4263-8180-043c54e22903"
    }
}

or

{
    "auth":{
        "passwordCredentials":{
            "username":"c18088be-16b1-4263-8180-043c54e22903",
            "password":"CDEe2k0T/HdiJWBMMbHyOA"
        },
        "tenantName":"c18088be-16b1-4263-8180-043c54e22903"
    }
}

The tenantName in the above requests is optional.

The response is json formatted unless it is requested otherwise via format request parameter or Accept header.

Example json response:

{"access": {
    "token": {
        "expires": "2013-06-19T15:23:59.975572+00:00",
