customer.link_cart

Link the caller’s active cart to their account (funnel provenance; guest stays unlinked).

• Scope: customer.self.write
• System: no
• Reachable from: POST /v1/commands/customer.link_cart (tenant credential) · MCP tool customer.link_cart · SDK client.call('customer.link_cart', …)
• Events: none — It attaches a session cart to a recognized customer; the fact a consumer would act on is cart.buyer_recognized, which the recognition emits.
