You are viewing the documentation for Blueriq 17. Documentation for other versions is available in our documentation directory.
The Blueriq web application is equipped with a REST API to expose methods to allow clients to control the flowing of the application. This page gives a description about the available services. For all of the below endpoints, an Accept
header of application/json
must be present in the request.
Authentication
Login user
POST /api/v2/login
Description
Login the user with the provided credentials
Request body
{ username: string, password: string }
{ "username": "testUser", "password": "secret" }
Before release 12.10, Blueriq expected the username and password to be in the request parameters of the login request (e.g. http://.../api/v2/login?username=testUser&password=secret). Since release 12.10, the username and password are retrieved from the login request body. For backwards compatibility the login information can still be retrieved from the request parameters as well.
The material theme sends the login information in the request body by default from release 12.10. It is possible to configure the theme to still use the legacy request parameter method of logging in, by configuring the backend module in your theme:
V2BackendModule.forRoot({ baseUrl: ...., legacyLoginWithQueryParams: true, }),
Response
204 No Content, if successful.
401 Unauthorized, if unsuccessful.
Logout user
POST /api/v2/logout
Parameters
Query Parameter | Expected Type | Description | Required |
---|---|---|---|
redirect_uri | string | URL to redirect to after logout | Conditional (see Response) |
Description
Logout the current user and close all Blueriq sessions
Response
204 No Content
302 Found
- if redirect_uri parameter is present
- the Location header contains the redirect_uri
400 Bad Request
- if the Runtime is configured with OpenID Connect and SSO Logout, and no redirect_uri parameter was received
- if a whitelist is defined for the redirect_uri parameter and the received redirect_uri is not whitelisted
Starting a Blueriq session
Start Shortcut
POST /api/v2/start/{shortcutName?}
Description
Starts a session by specifying the name of a shortcut.
Parameters
URL Segment | Expected Type | Description |
---|---|---|
shortcutName | string | The shortcut name, leave empty to start the default shortcut |
Example response
{ "sessionId": "2f177274-514d-4be9-aa3d-4a550ab9e724", "sessionTimeout": 1800 }
Start shortcut via GET request
Blueriq 17.10+ supports starting a session using the GET /api/v2/start/{shortcutName?}
endpoint, i.e. using the GET
method. This endpoint enables use-cases where e.g. a Blueriq application processes authorization redirects from an identity provider, giving the server access to request headers that wouldn't have been available if a browser client were to start the Blueriq session. The endpoint requires a redirectUrl
query parameter to be present where {sessionId}
is replaced using the Blueriq session id that has been started.
For example:
GET /api/v2/start/?redirectUrl=http%3A%2F%2Fexample.com%2Fsession%2F%7BsessionId%7D
Note that %7BsessionId%7D
corresponds with {sessionId}
in its URL-encoded form. Additionally, the unauthorizedUrl
query parameter can be provided to redirect to when the user is not authorized to start the shortcut. Any other errors can be redirected using the error-redirect
query parameter.
Start Project
POST /api/v2/start?project=export-kinderbijslag&flow=Main
Description
Parameters
Query parameter | Expected Type | Description | Required |
---|---|---|---|
project | string | The project to start | Yes |
flow | string | The flow to start | Only required if more than one exposed flow is present in the project |
version | string | The branch version | No |
languageCode | string | The project language | No |
ui | string | The UI variant to use, by default only mvc is supported | No |
theme | string | The project theme | No |
channel | string | the project channel | No |
Example response
{ "sessionId": "2f177274-514d-4be9-aa3d-4a550ab9e724", "sessionTimeout": 1800 }
Start project via GET request
Blueriq 17.10+ supports starting a session using the GET /api/v2/start/?project=...
endpoint, similar to the same ability when starting a shortcut. See the above documentation for shortcuts for details.
Interacting with a session
After having started a session using one of the /api/v2/start
endpoints, its initial page contents may be obtained via a POST
to /api/v2/session/{sessionId}/load
. The result of this call is the full page model, necessary for initial rendering of the page. Subsequently, events may be submitted to the runtime via a POST
to /api/v2/session/{sessionId}/event
, resulting in a response containing all changes (add, update, delete). In Blueriq each session may be part of a hierarchy of sessions. For example, in a DCM application, the session of a flow widget is a child session of the main dashboard session. An event in one session may cause changes in other sessions if Portal Messages are thrown. Therefore, the response of /api/v2/session{sessionId}/event
endpoint will contain changes in all sessions in the heirarchy. An example response containing the changes:
{"events":[ {"sessionId":"27390ee2-4968-4f27-ae71-3d6516ba06ec", "changes": { "changes":[ {"type":"add", "key":"P521-C0-F1", "model":{ "key":"P521-C0-F1", "name":"e.a2", "properties":{}, "questionText":"q2", "explainText":null, "dataType":"boolean", "rejectedValue":null, "readonly":false, "required":false, "hasDomain":false, "multiValued":false, "refresh":false, "displayLength":-1, "domain":[], "messages":[], "values":[], "type":"field", "styles":[] } } ] } ]}
In this example a field is added to the page. The available properties per element are listed in the REST Page Models.
Serialization
The serialization of page element to datamodel is handled by the IApiRendererFactory
, this renderer factory can be overridden to customize the serialization. In Java by use of the AquimaApiRendererFactory
annotation.
Load session information
After a session has been created using /api/v2/start
, the current state of the session can be obtained through:
POST /api/v2/session/{sessionId}/load
Description
Loads the information of the provided session.
Example response
{ "elements": [ { "key": "P381-C1", "name": "Single", "properties": { }, "children": [ "P381-C1-F0", "P381-C1-F1", "P381-C1-F7" ], "displayName": "Single Items", "contentStyle": "container", "type": "container", "styles": [ ] } ], "language": { "patterns": { "datetime": "yyyy-mm-dd hh:mm:ss", "date": "yyyy-mm-dd" }, "languageCode": "en-GB" } }
