The REST API provides endpoints that lets you implement identification with only a few API calls. Alternatively you can use one of our available SDKs.

See our API reference for detailed information about all the available endpoints and properties.


Follow these three steps to identify a user:

Step 1: Create a new identification session

When creating a new session, you can choose whether or not you want to specify which eID provider the user must use when identifying themselves. If no eID provider is specified, the user will be able to choose between all available providers associated with your Idfy account. In this example we will use Norwegian BankID.


Sample request body:

"IdentityProvider": "NO_BANKID_WEB",
"ReturnUrls": {
"Error": "[0]",
"Abort": "[1]&externalid=[2]",
"Success": "[1]&externalid=[2]"
"Language": "NO",
"GetSocialSecurityNumber": true

In the request we also specify the URL that the user is redirected to after the identification is completed, aborted by the user, or if an error occurs. Placeholders can be added to these URLs and will be replaced upon redirect.

A successful call returns the URL which the user must be redirected to in order to complete the identification process, as well as the unique ID for the session.

Step 2: Direct the user to the returned URL

When directing the user to the URL returned from step 1, the Norwegian BankID login interface is displayed:

You can also embed the URL in an iframe. This requires that you speficy the parent domain in the domain property of the request.

Step 3: Retrieve identified user data

After the identification process is complete and the user is redirected back to the specified successUrl, the session and associated user data can be retrieved with the unique session ID:
