Page (2/12) 1 ­ Introduction In this document, we specify the API and flow of events that will cover the functions of GrandID. 1.1 ­ What you should already know Before you read this document, you should have a basic understanding a programming language as well as JSON. 1.2 ­ Prerequisites Before starting ●
●
apiKey ­ Will be sent to you by mail authenticateServiceKey ­ Will be sent together with your apiKey 1.3 ­ How to detect a successfull login When you call the GetSession method you will get a json response. If this response contains a “username” key, this means the login is successfull. Example: { "sessionId":"d04a78214b193973ecc121d2f4b3a1e0", "username":"SE123123123123­1234", "userAttributes":{ "serialNumber":"SE123123123123­1234", "lastname":"Andersson", "firstname":"Anders" } } Note! The “userAttributes” object is different from each login methods. 2 ­ Implementation The client applicationAPI needs to do two REST request to GrandID API services as described below.

Explanation of schematics over GrandID ​
API 1) HTTP request to ​
https://client.grandid.com/json1.1/FederatedLogin 2) with your apiKey and authenticateServiceKey as GET parameters as well as a callbackUrl where we will redirect the authenticated user. 3) JSON response containing a redirectUrl and a sessionId is returned. 4) Your website should now redirect the browser to the redirectUrl. 5) GrandID will authenticate the user and redirect the user back to the url specified by the callbackUrl parameter. 6) The web application calls the API method GetSession at https://client.grandid.com/json1.1/GetSession​
together with apiKey, authenticateServiceKey and the session id returned from FederatedLogin 7) The response from GetSession is returning the user information. Svensk e­identitet AB Vaksalagatan 6 Org. nr: 556776­6992 753 20 Uppsala Tel: +46 18 481 19 00 www.grandid.com​
