All services require TLS (version 1.2 or higher) for transport security. In line with industry best practices the HIMSA IdP does not allow IFRAME based usage for any kind of user interactive authentication. An X-FRAME-OPTIONS HTTP header is always returned with the value ‘SameOrigin’.
Authentication
Noah ES contains an Identity Provider that supports OAuth 2.0 and OpenId Connect. The Identity Provider (IdP) is used for Authentication.
All services require a valid token from the IdP when called.
1. Request
Parameters that must be supplied:
URI and port number
QA environment: idp.qa.eu.noah-es.com:443
EU Production: idp.eu.noah-es.com:443
US Production: idp.us.noah-es.com:443
ClientId: Supplied by HIMSA
Scope: openid profile noah.cloud.app.users.api
If relevant for your app and app registration allows: offline_access
Flow: Authorization Code + PKCE
RedirectURI: IdP will redirect the client to this after successful authentication, with tokens for accessing the API. You must inform HIMSA about this, because we need to whitelist it
Extra options
culture-lcid: Culture LCID code for localizing the website
2. Response
When the client is redirected to the RedirectURI, the response will contain:
auth_code: Must be exchanged afterwards for an access token
Id token
tenantid claim: The tenantId that the user selected
3. Exchange auth_code for an access token
Note: This is done automatically if you are using HIMSA's .NET Client.
Access and refresh tokens may vary greatly in length. Make no assumptions about the contents. It can change at any point in time
4. Connecting to API
URI and port number
QA environment: api.qa.eu.noah-es.com:443
EU Production: api.eu.noah-es.com:443
US Production: api.us.noah-es.com:443
HIMSA's .NET Client:
Either use the constructor that takes an access token or a refresh token as input
5. Renewal of access token
Note: This is done automatically if you are using HIMSA's .NET Client.
Only if relevant for your app and if app registration allows.
Logging off
In case a user only set up 1 account and that account is of type single sign-on, logging off will redirect the user directly to the login page. In that case it will not be possible to set up a different account.
We suggest to redirect to the account selection page of the IdP after successfully logging off. It is then important to include "forcechoose" in the query string (with any value).
