Launches a real authentication flow targeting the default Salesforce Sandbox identity directory. Verifies the signature against your sandbox certificate.
Initiate Staff SSO ChallengeLaunches a real community authentication flow targeting the published Experience Cloud portal (/leememberportal).
Tests single sign-on deep-linking. Initiates an SSO login that forwards the target path in the RelayState parameter. After a successful handshake, Salesforce hands back the RelayState, and our callback redirects you automatically to a custom nested path (/auth/handoff?test=deeplink_success).
