Integration points
- Catalog/prices
- Stock events
- Orders inbound
- Shipment status outbound
Reliability
Queues, idempotency keys, nightly reconciliation.
Mapping and master data
Order statuses, SKU and price types need a written mapping table. Idempotency on order webhooks; dead letter on failure; seven-day nightly reconciliation. Staging 1C plus staging shop before production.
Multichannel
- CommerceML for catalog batch
- REST or events for realtime orders
- Orchestration layer if Ozon/WB also sell stock
- Returns and partial shipments as separate statuses
Five to ten days for production-grade exchange is realistic with prepared 1C. Support without field mapping docs fails within six months — document in Confluence from day one.
