Purpose and usage

What this endpoint does

Return invoice terms, checkout destination, payment detection, and settlement evidence.

When to use it

Re-read one invoice's immutable terms, versions, checkout posture, observations, payment evidence, settlement references, and fulfillment references before any follow-up action.

OUTCOME · Inspect

What changes

Read-only owner-scoped projection of one invoice; it cannot activate a merchant, publish a product, create checkout, assert payment, settle a wallet, fulfill an order, move value, or grant authority.

WHY IT MATTERS

Gives people and agents a contract-backed way to inspect invoice.
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 invoice_uuid (path) exactly as defined by the live contract.

WHAT TO DO NEXT

Open the canonical merchant, invoice, payment, or rotational-wallet record for the next stage and verify settlement independently before marking the commercial obligation complete.
Refresh invoice when its observation time, version, or lifecycle state is no longer adequate for the decision.

AGENT GUIDANCE

Use invoice only for the purpose and lifecycle stage described by this operation; do not treat it as authority for an adjacent action.
Supply the required invoice_uuid (path) 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.
Use response links and canonical identifiers instead of constructing internal service URLs or scraping the website.

INTEGRATION DECISION

CALLER ACTION: Accept the returned representation or receipt, then open the canonical merchant, invoice, payment, or rotational-wallet record for the next stage and verify settlement independently before marking the commercial obligation complete.
RETRY SAFETY: Repeat only when the integration needs a fresher authoritative projection.
STATE RECONCILIATION: Use returned identifiers and versions as the comparison point for later reads. 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.

INTEGRATION DECISIONinvalid_credentials

CALLER ACTION: Verify the canonical identifier and authenticated owner boundary. A 404 may intentionally conceal a resource outside the caller's authority.
RETRY SAFETY: Do not retry the unchanged identifier repeatedly. Refresh the relevant collection or lookup before choosing another identifier.
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: 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: Treat the failure as transient and preserve the last known good representation without presenting it as fresh.
RETRY SAFETY: Retry with bounded exponential backoff and jitter; stop after the integration's failure budget is exhausted.
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.

OPERATIONAL NOTES

Security and lifecycle guarantees

Return invoice terms, checkout destination, payment detection, and settlement evidence. Authoritative owner: commerce-service.
The Rust gateway validates the public contract and routes only to the authoritative owner; clients never address internal services directly.
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.

Reference version and availability details
