Using the Workflow component for e-commerce

on YouTube ↗31m

" summary

Built an order API for the biggest Swiss retailer using the Symfony workflow component as a state machine with explicit state transitions (open confirmed assigned picked up delivered plus cancelled variants). Implementation ties guard and enter/leave events to event‑driven listeners which recalc prices, revoke notifications, queue push/SMS and handle refunds. Pickers typically claim orders within two minutes. Result is clearer error messages, machine‑readable workflow docs and a scalable queue that actually works for high notification volume.
