Layer 4 — what happens when no other layer matched.

mode:

• passthrough — send the method's own name / the raw order text. The legacy behaviour and the default; the provider may reject it.
• carrier — send a shipping method you choose (requires trackstar_shipping_method_id).
• suppress — send nothing at all.

The single highest-value setting to configure in advance, since it needs no knowledge of the data.

Response Headers

Content-Type

401

Unauthenticated — the bearer token is missing, revoked, expired, or malformed. Never retry automatically; fix the credential. See the Errors guide.

403

Forbidden — the token lacks a required scope, the endpoint is not available to API tokens, or the user behind the token lacks the permission. A human must adjust the token scopes or user permissions; do not retry.

404

Not found — no record with the given identifier (or the route does not exist). Verify the ID before retrying.

422

Validation failed — the body is a field → messages map (Laravel shape) or the platform envelope with a stable machine-readable code. Fix the payload and resubmit.

429

Rate limited — platform limit is 1,000 requests/min; individual tokens may carry lower limits. Honor the Retry-After header before retrying. See the Rate Limits guide.
