ApplicationAttestationStep

public class ApplicationAttestationStep : OnboardingStep

An Onboarding step implementation which registers AttestationObserver to the SAPURLSession in the onboard, restore and reset passcode flow.

Use this step to ensure that requests your server receives come from legitimate instances of your application.

SAP BTP SDK For iOS uses Apple’s DeviceCheck framework to assert the legitimacy of a particular instance of your application to SAP Mobile Services from where administrators can assess the fraud risk and eventually enforce HTTP communication for asserted devices only.
