   A B2C Commerce developer needs to send order data to a downstream ERP system. The ERP system has a web service API that accepts JSON payloads. The business requires that orders are sent in near real-time, but the ERP system is sometimes slow to respond. The developer must ensure that no orders are lost and that the ERP system is not overwhelmed. What is the most appropriate integration pattern?

   • AUse a message queue to buffer orders and have a worker process send them to the ERP with a controlled concurrency limit.
   • BUse a scheduled job that runs every 5 minutes and sends all new orders in a single batch request.
   • CUse a synchronous web service call from the order creation hook and block until the ERP responds.
   • DUse OCAPI to push the order data directly to the ERP system.
