Start Smart Authentication

Calling verifyPolicy

To start the liveness verification, use the startSDK() method with the user's document ID, your account mobile token and CafVerifyPolicyListener interface.

Parameter	Type	Description	Required
mobileToken	String	Usage token associated with your CAF account	✅
personId	String	Identifier of the user who will perform the face liveness verification. It's recommended to use the user's identification document in this field, such as their CPF (Brazilian document ID), but it could be any other value.	✅
listener	CafVerifyPolicyListener	Interface which handles key events during the SDK's liveness detection process:	✅

Example

    private fun startSdk() {
        smartAuth.verifyPolicy(
            "userDocument",
            "myPolicyId",
            setupListener()
        )
    }

    private fun setupListener() = object : CafVerifyPolicyListener {
        override fun onSuccess(
            isAuthorized: Boolean,
            attemptId: String?,
            attestation: String?
        ) {
            println("CafVerifyPolicyListener.onSuccess isAuthorized: $isAuthorized")
            println("CafVerifyPolicyListener.onSuccess attemptId: $attemptId")
            println("CafVerifyPolicyListener.onSuccess attestation: $attestation")
        }

        override fun onPending(isAuthorized: Boolean, attestation: String) {
            println("CafVerifyPolicyListener.onPending isAuthorized: $isAuthorized")
            println("CafVerifyPolicyListener.onPending attestation: $attestation")
        }

        override fun onError(failure: CafFailure) {
            println("CafVerifyPolicyListener.onError failure: ${failure.message}")
        }

        override fun onCancel() {
            println("CafVerifyPolicyListener.onCancel")
        }

        override fun onLoading() {
            println("CafVerifyPolicyListener.onLoading")
        }

        override fun onLoaded() {
