Start Smart Authentication

Calling verifyPolicy

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

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	Closure that handles key events during the SDK's liveness detection process.	✅

Example

private func startSdk() {
    smartAuth?.verifyPolicy(
        personID: "userDocument",
        policyId: "myPolicyId",
        listener: setupListener()
    )
}

private func setupListener() -> CafVerifyPolicyListener {
    return { result in
        switch result {
        case .onSuccess(let response):
            print("CafVerifyPolicyListener.onSuccess isAuthorized: \(response.isAuthorized)")
            print("CafVerifyPolicyListener.onSuccess attestation: \(response.attestation)")
        
        case .onPending(let response):
            print("CafVerifyPolicyListener.onPending isAuthorized: \(response.isAuthorized)")
            print("CafVerifyPolicyListener.onPending attestation: \(response.attestation)")
        
        case .onError(let error):
            print("CafVerifyPolicyListener.onError failure: \(error.localizedDescription)")

        case .onCanceled(let error):
            print("CafVerifyPolicyListener.onCanceled failure: \(error.localizedDescription)")
        
        case .onLoading(let isLoading):
            print("CafVerifyPolicyListener.onLoading isLoading: \(isLoading)")
        
        case .onLoaded(let isLoaded):
            print("CafVerifyPolicyListener.onLoaded isLoaded: \(isLoaded)")
        }
    }
