High Level SAML API

Add SAML SSO functionality to your web application with just a few lines of code.

A high-level, configuration-driven SAML API hides the complexities of SAML SSO, making for a quick and easy implementation.

Configuration changes, including adding support for additional partner providers, can be made with zero code updates.

Initiating SSO from the SP

A SAML authn request is created and sent to the IdP.

            
// SP-initiated SSO.
SAMLServiceProvider.InitiateSSO(Response, returnUrl, partnerIdP);

Initiating SSO from the IdP

A SAML response is created and sent to the IdP.

            
// IdP-initiated SSO.
SAMLIdentityProvider.InitiateSSO(Response, userName, attributes, targetUrl, partnerSP);

Receiving the SAML Response

A SAML response is received from the SP and processed.

            
// SP or IdP-initiated SSO.
SAMLServiceProvider.ReceiveSSO(Request, 
            out isInResponseTo, 
            out partnerIdP, 
            out authnContext, 
            out userName, 
            out attributes, 
            out targetUrl);

Low Level SAML API

A low-level API provides complete control and flexibility.

The low-level SAML API allows access to the SAML profiles, protocols, bindings, assertions and metadata. For most scenarios, the high-level SAML API provides all the control you need in a simpler interface. For situations where this isn’t enough, the low-level SAML API is available.
