PURPOSE + BUSINESS CONTEXT

Create a reusable product with pricing, currency, fulfillment, and metadata.

WHEN THIS CALL IS USEFUL

Create one reusable merchant-owned catalog draft after resolving its SKU, exact price, denomination, public description, tax classification, and fulfillment evidence policy.

OUTCOME · Create or advance

What changes

Creates a DRAFT catalog record and immutable terms commitment only. It does not publish the offer, create checkout, issue an invoice, reserve inventory, collect payment, calculate tax, deliver anything, or move value.

WHY IT MATTERS

  • Gives people and agents a contract-backed way to advance product.
  • Connects catalog and invoice operations to payment collection and treasury reconciliation without making presentation state or a reserved address proof of payment.

ISOLATION + AUTHORITY

Tenant, workspace, merchant, product, customer, invoice, checkout, collection wallet, payment, custody, treasury settlement, tax or compliance policy, and finality remain distinct. Merchant configuration or invoice state cannot authorize wallet signing, move funds, prove settlement, or grant publisher, matching, or trading authority.

BEFORE YOU CALL

  • Authenticate at the documented boundary: bearer+scope.
  • Supply the required merchant_uuid (body), sku (body), name (body), unit_price (body), currency (body), fulfillment_policy (body), step_up_token (body) exactly as defined by the live contract.
  • Use one Idempotency-Key only for retries of the same byte-equivalent logical mutation.

WHAT TO DO NEXT

  • Re-read product using the canonical identifier returned by this operation.
  • Reconcile an ambiguous response with the same idempotency key before attempting another mutation.
  • Open the canonical merchant, invoice, payment, or rotational-wallet record for the next stage and verify settlement independently before marking the commercial obligation complete.

AGENT GUIDANCE

  • Use product only for the purpose and lifecycle stage described by this operation; do not treat it as authority for an adjacent action.
  • Supply the required merchant_uuid (body), sku (body), name (body), unit_price (body), currency (body), fulfillment_policy (body), step_up_token (body) exactly as defined by the live contract.
  • Distinguish merchant readiness, product availability, invoice issuance, checkout presentation, payment observation, wallet synchronization, treasury settlement, cancellation, and reconciliation.
  • After a timeout or conflict, read authoritative state before deciding whether an equivalent retry is safe.
MACHINE CONTRACT

RESPONSES

Status and payload examples

201A merchant-owned DRAFT product with canonical price, fulfillment policy, and immutable creation commitment is returned; no checkout, invoice, payment, or fulfillment is created.Mutation completed · JSON RESPONSE+
{}
INTEGRATION DECISION
CALLER ACTION
Accept the returned representation or receipt, then re-read product using the canonical identifier returned by this operation.
RETRY SAFETY
Do not repeat a successful mutation merely to confirm it. For one logical mutation, retain the same Idempotency-Key and byte-equivalent request. Never reuse that key for changed instructions.
STATE RECONCILIATION
Persist returned identifiers, versions, commitments, and receipts. Re-read the merchant or product version, invoice and linked payment-request state, and the exact network-scoped wallet projection before retrying with the same idempotency key and byte-equivalent request. Invoice state alone is not payment, settlement, or fulfillment finality.
400The merchant, SKU, name, description, exact price, currency, tax code, fulfillment policy, metadata, step-up token, signature, or idempotency key is malformed.Request must change · JSON RESPONSE+
{
  "code": "invalid_credentials",
  "message": "the supplied Hybrid credential is invalid"
}
INTEGRATION DECISIONinvalid_credentials
CALLER ACTION
Rebuild the request from the live OpenAPI operation and correct the rejected method, media type, header, parameter, or body field.
RETRY SAFETY
Do not retry the same invalid request. For one logical mutation, retain the same Idempotency-Key and byte-equivalent request. Never reuse that key for changed instructions.
STATE RECONCILIATION
Compare the submitted values with the documented constraints before another call. Re-read the merchant or product version, invoice and linked payment-request state, and the exact network-scoped wallet projection before retrying with the same idempotency key and byte-equivalent request. Invoice state alone is not payment, settlement, or fulfillment finality.
ESCALATE WHEN
Escalate when a protected transition remains ambiguous after authoritative Commerce, Payments, and operational-wallet reconciliation. Commerce settlement execution remains frozen; never manufacture value movement by combining invoice, payment, or wallet calls.
401The bearer credential is missing, expired, or invalid.Authentication required · JSON RESPONSE+
{
  "code": "invalid_credentials",
  "message": "the supplied Hybrid credential is invalid"
}
INTEGRATION DECISIONinvalid_credentials
CALLER ACTION
Discard the rejected credential, complete the documented authentication or reassertion flow, and rebuild any request signature with fresh timestamps and nonces.
RETRY SAFETY
Retry only with a newly valid credential and fresh replay-protection values. For one logical mutation, retain the same Idempotency-Key and byte-equivalent request. Never reuse that key for changed instructions.
STATE RECONCILIATION
Assume the outcome is unknown only when the connection failed after transmission; otherwise authentication failed before domain work. Re-read the merchant or product version, invoice and linked payment-request state, and the exact network-scoped wallet projection before retrying with the same idempotency key and byte-equivalent request. Invoice state alone is not payment, settlement, or fulfillment finality.
ESCALATE WHEN
Escalate when a protected transition remains ambiguous after authoritative Commerce, Payments, and operational-wallet reconciliation. Commerce settlement execution remains frozen; never manufacture value movement by combining invoice, payment, or wallet calls.

INTEGRATION DECISIONinvalid_credentials
CALLER ACTION
Verify the exact scope, tenant or workspace membership, owner boundary, step-up purpose, feature policy, and resource eligibility. Never broaden authority automatically.
RETRY SAFETY
Do not retry until the missing authority or policy condition has been deliberately resolved with least privilege.
STATE RECONCILIATION
Confirm the caller and resource resolve to the same authority boundary for workspace-isolated merchant profiles, catalog publication, invoices, linked payment requests, and verify-only rotational-wallet observations.
ESCALATE WHEN
Escalate when a protected transition remains ambiguous after authoritative Commerce, Payments, and operational-wallet reconciliation. Commerce settlement execution remains frozen; never manufacture value movement by combining invoice, payment, or wallet calls.

CALLER ACTION
Stop the mutation sequence and fetch the latest authoritative resource, lifecycle state, version, ETag, reservation, or existing idempotency result.
RETRY SAFETY
Retry only after reconciling the conflict. For one logical mutation, retain the same Idempotency-Key and byte-equivalent request. Never reuse that key for changed instructions.
STATE RECONCILIATION
Re-read the merchant or product version, invoice and linked payment-request state, and the exact network-scoped wallet projection before retrying with the same idempotency key and byte-equivalent request. Invoice state alone is not payment, settlement, or fulfillment finality.
ESCALATE WHEN

CALLER ACTION
Preserve the exact request and treat the outcome as uncertain until authoritative state proves whether it committed.
RETRY SAFETY
Reconcile before retrying. For one logical mutation, retain the same Idempotency-Key and byte-equivalent request. Never reuse that key for changed instructions. Use bounded backoff with jitter.

OPERATIONAL NOTES

Security and lifecycle guarantees

  • Create a reusable product with pricing, currency, fulfillment, and metadata. Authoritative owner: commerce-service.
  • The Rust gateway validates the public contract and routes only to the authoritative owner; clients never address internal services directly.
  • Mutations are retry-safe only when the same Idempotency-Key and canonical request body are reused.
  • The tables and examples are derived from the current gateway source OpenAPI. Re-fetch the deployed OpenAPI before execution; deployment status is shown separately on this page.
  • Only parameters present in the OpenAPI operation are accepted; undocumented query keys fail closed with HTTP 422.
DOCUMENTATION STATUS

This route is implemented in canonical gateway source and appears in the production OpenAPI snapshot observed 2026-09-11T06:35:11.572Z. Authentication, tenant, feature, venue, and market policy still apply.
