Operation ID

getInvoice

Canonical origin

Not declared; gateway routing required

Purpose and use cases

GET /invoices/{reference}

The owning App is Vision Accounting. Accounting owns financial records, exact arithmetic, approvals, audit evidence, workspace grants, and ledger invariants.

Business use cases and out-of-scope behavior are not yet declared in the approved OpenAPI description.

Request

GET /invoices/{reference}

This contract intentionally declares no direct server URL. Obtain the routed App origin before attempting the request.

Authentication and authorization

Send a Vision-issued bearer token for the exact App audience. The token must include the accounting entitlement and satisfy the aws-… accounting workspace required binding.

• Required scope: accounting:invoices:read

Human roles are not declared in OpenAPI. Record-level and business permission checks remain the owning App's authority.

Headers

• Authorization: Bearer <access-token> — required.
• Accept: application/json — recommended where a JSON response is declared.

Undeclared tracing, idempotency, conditional-request, and version headers are not assumed on this page.

Path and query parameters

Request body

This operation declares no request body.

Runnable examples

curl '${APP_BASE_URL}/invoices/${REFERENCE}' \
  --request GET \
  --header 'authorization: Bearer ${ACCESS_TOKEN}' \
  --header 'accept: application/json'

const response = await fetch('${APP_BASE_URL}/invoices/${REFERENCE}', {
  method: 'GET',
  headers: {
    authorization: `Bearer ${ACCESS_TOKEN}`,
    accept: 'application/json',
  },
}

if (!response.ok) throw new Error(`Vision API ${response.status}`)
const result = await response.json()

import json
import urllib.parse
import urllib.request

request = urllib.request.Request(
    '${APP_BASE_URL}/invoices/${REFERENCE}',
    data=None,
    headers={
    "Accept": "application/json",
    "Authorization": "Bearer <ACCESS_TOKEN>"
},
    method='GET',
)
with urllib.request.urlopen(request, timeout=30) as response:
    result = json.load(response)

The current TypeScript reference client covers Platform token exchange and core reads. No native SDK helper is declared for this operation; use the HTTP contract directly and follow the SDK guidance.

Responses

Success response schema

Errors and troubleshooting

Error bodies and codes are shown only where the approved contract declares them. Use status, the declared error schema, and any correlation identifier returned by the App; do not infer that two Apps share one envelope.

• 401 — Safe Accounting error
• 403 — Safe Accounting error
• 404 — Safe Accounting error

Collection behavior

Pagination: not declared. Filtering/search: not declared. Sorting: not declared.

Cursor lifetime, cursor binding, stable ordering, maximum traversal, and unknown-filter behavior are not assumed unless stated by a parameter description or schema constraint above.

Operational behavior

• Rate limit: No operation-specific limit or 429 response is declared.
• Retry: Retry only when the documented error model or response headers authorize it. Timeout and backoff values are not declared by this operation.
• Idempotency: No idempotency header or replay window is declared.
• Concurrency: No ETag, If-Match, or optimistic-version header is declared.

Security and privacy

• Keep client credentials and bearer tokens on trusted servers.
• Send only to the exact approved HTTPS origin and audience.
• Treat response data according to the owning App's classification and retention policy; the OpenAPI contract does not itself grant data access.
• Do not log credentials, tokens, complete private payloads, or secrets.

Edge cases and known documentation gaps

• No detailed operation description.
• No direct server URL; gateway routing is unresolved here.
• One or more parameters have no field-level description.
• No machine-readable success schema.
• Business roles, timeout, retry budget, rate value, idempotency window, and concurrency behavior are absent unless explicitly stated above.
