Resume cart from receipt ID
AI agents use cart_resume_from_receipt_id to create or update resources in MCP Dynamics 365 Commerce Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your MCP Dynamics 365 Commerce Server environment.
Resuming a cart from a receipt ID creates or restores a cart session in the commerce system, which is a stateful write operation. It modifies system state by recreating/activating a cart object based on a prior receipt. No irreversible destruction occurs, and no financial transaction is committed directly.
