Limits & errors

Pagination

List endpoints accept:

Query	Default	Max
limit	50	200
offset	0	—

Smaller pages reduce payload size; larger pages mean fewer round trips. Stay within the maximum so responses stay predictable.

Typical HTTP status codes

HTTP	Meaning
400	The request body or query parameters are invalid. The response body is JSON with a short human-readable detail message.
403	Authentication failed (missing key, wrong key, or failed HMAC when required).
404	The resource does not exist for your supplier account (for example unknown SKU or order id).

Exact shapes are listed in the OpenAPI reference.
