Fail Authorization Request

This API generates a content of an error authorization response that the authorization server implementation returns to the client application.

Description

This API is supposed to be called from within the implementation of the authorization endpoint of the service in order to generate an error response to the client application. The description of the /auth/authorization API describes the timing when this API should be called. The response from /auth/authorization/fail API has some parameters. Among them, it is action parameter that the authorization server implementation should check first because it denotes the next action that the authorization server implementation should take. According to the value of action, the authorization server implementation must take the steps described below. INTERNAL_SERVER_ERROR When the value of action is INTERNAL\_SERVER\_ERROR, it means that the request from the authorization server implementation was wrong or that an error occurred in Authlete. In either case, from the viewpoint of the client application, it is an error on the server side. Therefore, the service implementation should generate a response to the client application with HTTP status of "500 Internal Server Error". Authlete recommends application/json as the content type. The value of responseContent is a JSON string which describes the error, so it can be used as the entity body of the response. The following illustrates the response which the service implementation should generate and return to the client application.

HTTP/1.1 500 Internal Server Error
Content-Type: application/json
Cache-Control: no-store
Pragma: no-cache
{responseContent}

The endpoint implementation may return another different response to the client application since "500 Internal Server Error" is not required by OAuth 2.0. BAD_REQUEST When the value of action is BAD\_REQUEST, it means that the ticket is no longer valid (deleted or expired) and that the reason of the invalidity was probably due to the end-user's too-delayed response to the authorization UI. A response with HTTP status of "400 Bad Request" should be returned to the client application and Authlete recommends application/json as the content type. The value of responseContent is a JSON string which describes the error, so it can be used as the entity body of the response. The following illustrates the response which the service implementation should generate and return to the client application.

HTTP/1.1 400 Bad Request
Content-Type: application/json
Cache-Control: no-store
Pragma: no-cache
{responseContent}

The endpoint implementation may return another different response to the client application since "400 Bad Request" is not required by OAuth 2.0. LOCATION When the value of action is LOCATION, it means that the response to the client application must be "302 Found" with Location header. The parameter responseContent contains a redirect URI with (1) an authorization code, an ID token and/or an access token (on success) or (2) an error code (on failure), so it can be used as the value of Location header. The following illustrates the response which the service implementation must generate and return to the client application.

HTTP/1.1 302 Found
Location: {responseContent}
Cache-Control: no-store
Pragma: no-cache

FORM When the value of action is FORM, it means that the response to the client application must be 200 OK with an HTML which triggers redirection by JavaScript. This happens when the authorization request from the client application contained response\_mode=form\_post. The value of responseContent is an HTML which can be used as the entity body of the response. The following illustrates the response which the service implementation must generate and return to the client application.

HTTP/1.1 200 OK
Content-Type: text/html;charset=UTF-8
Cache-Control: no-store
Pragma: no-cache
{responseContent}
