 ## Usage
 
 This example protects an order endpoint end to end. Your API calls a checkpoint before placing the order. When the workflow needs more input from the user, such as MFA, your frontend gathers it with the Client SDK and calls your API again with the verification ID. See [Identifiers](#identifiers) for what each ID is and [useVerification](#useverification) for how the second call works.
