About Freja eID

Freja eID is an electronic identification (eID) solution that citizens and organisations can use for authentication and signing. The essential part of Freja eID service is a smartphone application used for login and signing to all the services that are connected to the user's eID. The second part is a web portal – My Pages – where the user can control how their eID is to be used and has a full record of user history. 

About this Document

This document describes the client library - Freja eID Client - that simplifies coding against the Freja ID Relying Party API when it comes to using Freja eID Services. Using this library will also make your code more robust, as the library provides error handling, parameter validation and other helpful features.

About the Client Library

Our client library is written in Java programming language. The intended reader of this document is a Java developer aiming to utilise the Freja eID Client for integrating the Relying Party's back-end system with Freja eID’s mobile service. We, therefore, assume a degree of proficiency in object-oriented programming, as well as developing applications using web services and microservices.

You can find the Java source code of our library on GitHub.
