Interacting with a session
In Blueriq, each session is part of (usually) one subscription in order to allow receiving changes from multiple Blueriq sessions simultaneously. After having started a session using one of the /api/v1/start endpoints, its initial page contents may be obtained via a POST to /api/v1/subscription/{subscriptionId}/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/v1/subscription/{subscriptionId}/session/{sessionId}/event, resulting in a response containing all changes (add, update, delete) for each session that is attached to the subscription. An example response containing the changes:
Change Events
{"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 V1.
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.

After a session has been created using /api/v1/start, the current state of the session can be obtained through:
