ACP Orders & Webhooks
Implements Agentic Commerce Protocol (ACP) order lifecycle management and secure HMAC-signed webhook event delivery.
This skill provides a standardized framework for managing the complete order lifecycle within Agentic Commerce environments, covering everything from initial creation to final delivery or cancellation. It enables developers to implement robust order tracking, fulfillment updates, and post-purchase adjustments like refunds or returns using the ACP specification. A core focus is placed on security and reliability, providing patterns for HMAC-SHA256 signed webhook emission, timing-safe signature verification, and idempotent event delivery to ensure seamless communication between merchants and AI agents.
