Steps
Set addOnServices.isDropOffOTPRequired and addOnServices.attendedDelivery to true when booking the delivery
Retrieve the generated passcode from the otpDetails.pickupOTP field returned in the delivery status webhook sent immediately after booking
Communicate the passcode to the customer through your own notification channel at checkout and again before delivery, since Walmart does not message the customer directly
Understand the driver-facing flow: the delivery cannot be marked complete in the Spark Driver app until the customer provides the passcode
Handle the return flow using otpDetails.returnOTP for cases where the customer cannot provide the pickup passcode and the order is returned to the pickup point
Known gotchas
The client, not Walmart, is responsible for delivering the passcode to the customer — there is no built-in customer notification, so failing to communicate it in time causes failed deliveries
The passcode is fixed for the lifetime of the orderId and included in every delivery status webhook, so don't assume it must be re-requested per event
If the customer can't produce the OTP, the driver returns the order rather than leaving it, which needs a defined re-delivery/refund process on the merchant side
