Glossary

Item code

Unique product identifier (e.g. GOOGLE-5USD-KOXx). Used in catalog, stock check, and order creation. Same as item_id in query/body parameters.

Envelope

Standard response shape: success (boolean), message (string), data (object). All API responses use this structure.

order_id

Numeric ID returned when you create an order. Use it with GET /orders/{id} to fetch order status and codes.

order_no

Human-readable order reference (e.g. ORD-2026-001) for display and support.

Stock check

Request to see if a product is available in a given quantity. Use POST /orders/check with item_id and quantity. Not the same as checking the status of an existing order.
