Response example

Here is a response example from the "Create a session" request for the headless flow:

{
"id": "425cbb48--...",
"accountId": "a-sdge-...",
"status": "CREATED",
"idpData": {
"deviceLink": "https://test.audkenniapp.is/device-link?deviceLinkType=Web2App&sessionToken=..."
},
"allowedProviders": [
"audkenni-app"
],
"flow": "headless",
"requestedAttributes": [
"dateOfBirth",
"firstName",
"lastName",
"name",
"nin",
"age"
],
"sessionLifetime": 1200,
"expiresAt": "2026-06-29T11:08:34.9495067+00:00"
}

For the complete documentation index, see llms.txt

The CREATED status means the end-user has not started to authenticate yet.

The response returns the necessary data directly in the idpData object, which you use to drive the authentication in your own custom user interface:

2. Obtain user information (Get session status)

For the complete documentation index, see llms.txt

Make an HTTP GET request to the /sessions endpoint to poll for information regarding the session and ongoing authentication.

Upon successful authentication, a response is returned that contains the user information requested in the "Create a new session" call carried out earlier.

For the complete documentation index, see llms.txt
