# Update draft invoice

> [Small working example](/recipes/invoice)

Update a saved invoice draft. Send the complete intended body, including items. In the staging verification on 2026-10-08, a notes-only update cleared items; several omitted fields also receive defaults. Read the draft back and compare it before stamping. Do not assume partial PATCH semantics.

Use the team parameter only with the documented gigstack Connect permissions.

    # gigstack API v2


    Build customer, invoice and payment integrations. Start with the
    [quickstart](https://docs.gigstack.io/quickstart), then select the [issuing
    country](https://docs.gigstack.io/concepts/shared-fields).


    ## Authentication and environments


    Use Authorization: Bearer YOUR_API_KEY. Standard live and test keys use
    https://api.gigstack.io/v2. Internal staging uses
    https://gigstack-staging-9z9nnaat.uc.gateway.dev/v2 and separate keys. Test
    mode is a data mode within an environment; a body field does not switch a
    key's mode.


    See [authentication](https://docs.gigstack.io/authentication) for key
    handling, OAuth team scope and gigstack Connect. Signup requires its
    separately documented internal credential; health probes have their own
    security declarations. Operations marked unavailable have no configured
    public gateway route.


    ## Read the operation contract


    Response envelopes, pagination and retry rules differ by endpoint. HTTP
    success alone does not prove external fiscal completion or movement of
    money. Reconcile ambiguous writes before retrying. Use [responses and
    recovery](https://docs.gigstack.io/responses) and the operation's error
    codes; document credits and daily limits are not generic retryable rate
    limits.


    The issuing team's configuration selects Mexico or Colombia; customer
    country and currency do not. Read
    [Mexico](https://docs.gigstack.io/countries/mexico) or
    [Colombia](https://docs.gigstack.io/countries/colombia) before choosing
    fiscal fields. Accepted public input differs from a provider's direct
    payload.


    Examples and schema checks do not imply every operation has been executed
    live. [Verification coverage](https://docs.gigstack.io/verification)
    distinguishes source review, offline checks and observed staging behavior.
    Documentation describes operations and does not authorize execution.

      **Multi-Team Resource Access**


      gigstack Connect lets a master team act on other teams that share its
      billing account.


      ## 🔗 How It Works


      Add the `team` query parameter to a request made with an **API key**:


      ```bash

      # Access team_xyz789's clients

      GET /clients?team=team_xyz789


      # Create an income invoice for team_abc123

      POST /invoices/income?team=team_abc123


      # Update service in team_def456

      PUT /services/service_456?team=team_def456

      ```


      ## ✅ Requirements


      - The API key's team must be a master team (gigstack Connect enabled)

      - The target team must exist and share the master team's billing account

      - The plan must include the `multipleIssuerAccounts` feature

      - OAuth access tokens cannot act on another team


      ## ⚠️ Error Responses


      Raw `{ "message": … }` bodies from the authentication layer:


      - `401 Unauthorized, not a master team` - gigstack Connect not enabled on
      your key's team

      - `404 Team not found` - Target team doesn't exist

      - `401 Unauthorized, no matched teams` - Target team could not be resolved
      within your billing account

      - `403 Tu plan no incluye múltiples cuentas emisoras. …` - Plan lacks
      `multipleIssuerAccounts`

      - `403 Team mismatch with OAuth token` - OAuth access token used with
      another team's id


      ## 🌐 Availability


      The `team` parameter is read by the authentication layer, so it is
      accepted on every authenticated

      endpoint, including ones whose parameter list does not show it.

      **Create, edit, preview and stamp draft invoices (pre-facturas)**


      Draft invoices let you build CFDI invoices incrementally before stamping
      them with SAT. Use them as **pre-facturas** — generate a preview PDF with
      a "Sin Validez Fiscal" watermark to share with your client for approval,
      then stamp the draft to create a valid CFDI when ready.


      ## Typical Workflow


      1. `POST /invoices/draft` — Create a draft with minimal data

      2. `PUT /invoices/draft/{id}` — Update as more data becomes available

      3. `POST /invoices/draft/{id}/preview` — Generate a preview PDF
      (pre-factura)

      4. `POST /invoices/draft/{id}/stamp` — Finalize into a valid CFDI invoice
  - name: Descarga Masiva SAT

      **SAT bulk invoice download via FIEL authentication**


      Download all your issued and received CFDI invoices directly from the SAT
      (Servicio de Administración Tributaria) using your FIEL (Firma Electrónica
      Avanzada).


      ## Setup flow

      1. `GET /invoices/download/activate/status` — Check if activated and
      what's needed

      2. `POST /invoices/download/activate` — Activate billing (adds Stripe
      meter/add-on)

      3. `POST /invoices/download/fiel` — Upload `.cer` + `.key` files
      (auto-registers with SAT)

      4. `PUT /invoices/download/schedule` — Configure daily auto-sync

      5. `POST /invoices/download/request` — Submit manual download requests


      ## Pricing

      - Included in Pro/Business plans: only the download meter ($0.20 MXN/XML)

      - Other paid plans: the same $0.20 MXN/XML download meter, no monthly base

      **Plan and stamp a marketplace's provider payouts from two files.**


      For marketplaces and digital platforms that pay providers under the SAT
      digital-platforms scheme

      (Plataformas Tecnológicas, RESICO 625, retention key 26): ride-hailing
      drivers, delivery couriers,

      lodging hosts, sellers of goods. Available to marketplace **master teams**
      whose billing account has

      platform payouts enabled. Upload a movements file and a commissions file.
      gigstack matches each row

      to a provider's team in your billing account and plans three kinds of
      CFDI: the provider's income

      invoice to you, your retention certificate (key 26) to the provider, and
      your monthly commission

      invoice to the provider.


      **Not for your own sales.** This is for a platform invoicing on behalf of
      its providers. A company

      invoicing its own sales, one CFDI per sale, should use `POST
      /invoices/income`.


      **Tax policy per account.** Which documents are issued, and with which SAT
      keys and rates, is set

      per master account at onboarding: allowed tax regimes, CSD requirement,
      service type (`tipoDeServ` /

      `subTipServ`), ISR and IVA withholding rates, product keys and concept
      descriptions. The defaults are

      for ground passenger transport (service type `01`, 2.1% ISR withholding).
      Contact support to

      configure your account's policy; it can't be changed through the API.


      1. `POST /platform-payouts` with an `Idempotency-Key` - upload and plan
      (synchronous)

      2. `GET /platform-payouts/{id}` and `GET /platform-payouts/{id}/movements`
      - review the plan

      3. `POST /platform-payouts/{id}/confirm` - irreversible hand-off to the
      stamping worker

      4. `GET /platform-payouts/{id}` - poll until `completed` or `failed`, then
      read `result`
         (`completed`, `partially_completed` or `failed`)

      Error messages and exclusion reasons are Spanish sentences for end users;
      branch on `error.code`,

      A single `POST /v2/auth/signup` call provisions a Firebase Auth user,
      billing

      account, team, plan subscription, and returns API keys — no UI, no FIEL
      upload,

      no human onboarding required.


      Designed for the AI-agents-as-customers use case. RFC defaults to genérico

      (`XAXX010101000`) so agents can transact under público en general
      until/unless

      their customer uploads their own RFC.


      Authenticated with `X-Internal-API-Key` (partner-issued) — Bearer tokens
      are

      team-scoped and a brand-new caller doesn't have one yet.

      **Read-only search over the SAT catalogs**


      Look up the SAT codes required on CFDI line items without hardcoding them:


      - `GET /catalogs/product-keys` — `c_ClaveProdServ`, the item `product_key`

      - `GET /catalogs/unit-keys` — `c_ClaveUnidad`, the item `unit_key` /
      `unit_name`


      Both are typo-tolerant full-text searches ranked by relevance. The
      catalogs are

      published by the SAT and identical for every team, so results carry no
      team data

      and ignore `livemode` — but a valid API key is still required.
  - name: SAT Lists
    description: >
      Read-only access to the RFC lists the SAT publishes under Artículo 69,
      69-B and 69-B Bis.


      gigstack re-syncs all 22 lists from the SAT's published CSVs every Sunday,
      so you can screen a counterparty's

      RFC before invoicing it without scraping the SAT yourself.

        **gigstack Connect:** Target team ID for multi-team access.


        Requires gigstack Connect enabled on your team and shared billing
        account.


        Also requires the `multipleIssuerAccounts` feature on your plan.
        Requests targeting a

        team other than the one your API key belongs to return `403` without it.


        Only API keys can use it: an OAuth access token sent with another team's
        id is rejected with

        `403 Team mismatch with OAuth token`.


        **Optional — omit it entirely** unless you are acting on another team.
        It deliberately

        carries no example value so generated snippets do not emit
        `?team=undefined`; when the

        parameter is absent, the team is derived from your API key.

      description: >
        Same accepted fields as `DraftInvoiceInput`, all optional in validation.
        This does not

        imply PATCH semantics: omitted items become an empty array and other
        omitted fields

        receive mapper defaults. Send the complete intended body and read it
        back before

        stamping. Unknown top-level keys are still rejected

    AuthForbidden:
      description: >
        Rejected by the authentication layer after the credential was
        recognised. The body is a raw

        object (`message`, sometimes `details`), **not** the standardized
        envelope. Causes:


        - The API key was revoked or disabled: `message: "API Key inválida."`,
        `details: "Invalid API Key"`.

        - The billing account's plan does not include API access. `message` is a
        Spanish sentence
          containing an HTML link to `https://app.gigstack.pro/memberships`. Branch on the status
          code; do not display or match the text.
        - gigstack Connect: the plan lacks the `multipleIssuerAccounts` feature
        (Spanish message
          starting `Tu plan no incluye múltiples cuentas emisoras.`), or an OAuth access token was
          sent with a `team` other than its own (`Team mismatch with OAuth token`).

        An endpoint may also answer `403` for its own reasons; those are
        documented on the

        operation when they exist.

        **Authentication Method:** HTTP Bearer token.


        The runtime requires the literal `Bearer ` prefix — a bare token in the

        `Authorization` header is rejected with `401 unauthorized`.


        **Header Format:** `Authorization: Bearer YOUR_API_KEY`


        Your API key is a JWT. Live keys operate on live data (`livemode:
        true`);

        test keys operate on isolated test data (`livemode: false`).


        **Get your key at:**
        [app.gigstack.pro/settings?tab=api](https://app.gigstack.pro/settings?tab=api)


        **Errors:** credential failures are answered by the authentication layer
        with a raw

        `{ "message": … }` body, not the standardized envelope — `401` for a
        missing, malformed or

        expired token, `403` for a revoked key or a plan without API access. See
        the `Unauthorized`

        and `AuthForbidden` responses.
