# Get an invoice

> Read one invoice issued to your company.

**Requires scope:** `view:billing` — see [Required scopes](/getting-started/authentication#required-scopes-finance-api).

Returns one issued invoice in full. Unsent, voided, foreign and unknown invoice ids all answer the same `404 invoice-not-found`.


## OpenAPI

````yaml api-reference/Finance-API-Specs.yaml GET /billing/invoices/{invoiceId}
openapi: 3.1.0
info:
  title: Venly Finance API
  description: >
    REST API for the Venly Finance platform:

    - Party management (Individuals & Organisations)

    - Identity verification — hosted KYC/KYB links and Sumsub share-token
    forwarding

    - Account management with party association

    - Wallet balances & token allowances on supported chains

    - Virtual bank accounts for global pay-in (EUR SEPA, USD ACH/WIRE/RTP/SWIFT)

    - Fiat-to-crypto payment sessions (pay-in)

    - Bank pay-outs — beneficiary allow-listing, routes, and PULL/PUSH pay-outs

    - Account-to-account fiat & crypto transfers

    - EIP-2612 permits and allowances

    - Webhook registration for asynchronous event delivery


    ## Authentication


    All endpoints use OAuth2 client credentials. Obtain a token first, then
    include it in every request:


    **Step 1 — Get a token:**

    ```bash

    curl -X POST
    https://login.venly.io/auth/realms/VenlyFinance/protocol/openid-connect/token
    \
      -H "Content-Type: application/x-www-form-urlencoded" \
      -d "grant_type=client_credentials&client_id={CLIENT_ID}&client_secret={CLIENT_SECRET}"
    ```


    **Step 2 — Use the token:**

    ```

    Authorization: Bearer {access_token}

    ```


    Tokens expire after **5 minutes**. Implement refresh logic in your client.


    ## Selecting a tenant


    A token that grants more than one tenant must say which one each request is
    for, in the

    `x-tenant-id` header. With a single-tenant token, omit it. Any value you
    send must exactly match a

    tenant the token grants; a missing, malformed or foreign value is answered
    with a generic

    `403 forbidden` that reveals nothing about which tenants exist. Send the
    header at most once.


    ## Request correlation


    Every response — including `401` and `403` — carries an `X-Correlation-Id`
    header identifying the

    operation in our logs. Quote it in a support request. You may supply your
    own, as

    `X-Correlation-Id` or (as a fallback) `X-Request-Id`, matching
    `^[A-Za-z0-9_.:-]{1,64}$`. A value

    outside that shape is replaced with a generated one rather than rejected.

        Omit it when the token

        grants exactly one tenant; it is **required** when the token grants more
        than one. A supplied

        value must exactly match a tenant the token grants.


        Absent when required, blank, malformed, or naming a tenant the token
        does not grant — each gets

        the same generic `403 forbidden`, which reveals neither whether a tenant
        exists nor which ones

        you may use. Send the header once: a repeated header is rejected the
        same way.
