WooCommerce Engineering

Workflow

1. Establish WooCommerce version, HPOS state, checkout implementation and relevant extensions.
2. Use WooCommerce CRUD APIs and supported extension points instead of direct post/meta assumptions.
3. Treat cart, checkout, order and payment state as server-owned.
4. Make callbacks/webhooks and payment transitions idempotent.
5. Test guest/authenticated paths and storage/checkout modes covered by compatibility claims.

Conditional references

• HPOS → references/hpos.md.
