The handler passes the value straight to `Luxon.fromMillis()` and compares it against `Luxon.now().toMillis()`; a seconds-based timestamp resolves to 1970 and is silently accepted. Defaults to now. A future date returns `400`. - **send_email** / **ignore_emails** (optional): `ignore_emails` takes precedence — the handler resolves `ignore_emails ?? (send_email === false)`, so `ignore_emails: true` suppresses notifications even when `send_email: true`. - **amount_received** (optional): cumulative amount received so far, in the payment's currency. Omit it, or send the full payment amount, to mark the payment `succeeded` (unchanged default behavior). Send less than the full amount to record a partial top-up: the payment is set to `partially_paid` instead, triggering a partial payment complement on the related PPD invoice. Requires the team's `automatePartialPaymentComplements` default to be on and a `payment_complement` automation already present on the payment. Sending more than the payment amount returns `400`. ## OpenAPI ````yaml openapi.json POST /payments/{id}/paid openapi: 3.0.3 info: title: gigstack API v2 description: > # 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. version: 2.0.0 contact: name: Gigstack API Support url: https://gigstack.io email: support@gigstack.io license: name: Proprietary url: https://gigstack.io/terms termsOfService: https://gigstack.io/terms servers: - url: https://api.gigstack.io/v2 description: > Public API for standard live and test-mode keys.

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 description: > **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 fee - name: Payments description: Payment processing, tracking, and refund management - name: Receipts description: Receipt creation and management with CFDI stamping capabilities - name: Retentions description: >- Tax retention documents (CFDI Retenciones 2.0) — creation, stamping, cancellation, and file retrieval - name: Platform Payouts description: > **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`, `reason_code` and `exclusion_codes`. - name: Documents description: > SAT supporting documentation (contracts, delivery/payment proofs, communications) — upload metadata, compliance review, AI extraction, and linking to invoices, payments, receipts and clients. - name: Teams description: Team management, settings, and member administration - name: Users description: User account management and password operations - name: Auth description: > **API-only signup for AI agents and partner integrations.** 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.

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. externalDocs: description: Complete API Documentation & Guides url: https://docs.gigstack.io paths: /payments/{id}/paid: post: tags: - Payments summary: Mark payment as paid description: > Mark a payment as paid with the specified payment form. **gigstack Connect:** Mark other teams' payments as paid using the `team` parameter. ## Required Information - **payment_form** (required): SAT-compliant payment form code (`01`–`31`, `99`) - **date** (optional): when the payment was received, in **Unix epoch milliseconds** (13 digits).

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. **Example:** `?team=team_xyz789` schemas: MarkPaymentAsPaidInput: type: object additionalProperties: false required: - payment_form properties: date: description: > When the payment was received, as a Unix epoch timestamp in **milliseconds** (13 digits). The handler feeds this value directly to `Luxon.fromMillis()` and compares it to `Luxon.now().toMillis()`, so a seconds-precision value is interpreted as a 1970 date rather than rejected. Defaults to now; a future value returns `400`. example: 1767225600000 type: number nullable: true send_email: description: Whether to send email notifications. Overridden by `ignore_emails`. example: true type: boolean nullable: true ignore_emails: description: > Suppress notification emails. Takes precedence over `send_email` — the handler resolves `ignore_emails ?? (send_email === false)`. example: false type: boolean nullable: true amount_received: description: > Cumulative amount received so far, in the payment's currency (**not** cents — converted internally to match the payment's stored amount). Omit it, or pass the full payment amount, to mark the payment fully `succeeded` (the default behavior). Pass a value **less than** the payment amount to record a partial top-up instead: the payment is set to `partially_paid` with this cumulative amount, which must exceed the amount already received. A value **greater than** the payment amount is rejected with `400`. Partial funding additionally requires the team's `automatePartialPaymentComplements` default to be enabled and the payment to already carry a `payment_complement` automation (i.e. it originated from a PPD invoice flow) — otherwise the request is rejected with `400`. example: 500 type: number nullable: true minimum: 0.01 payment_form: description: SAT payment form code type: string enum: - '01' - '02' - '03' - '04' - '05' - '06' - '08' - '12' - '13' - '14' - '15' - '17' - '23' - '24' - '25' - '26' - '27' - '28' - '29' - '30' - '31' - '99' StandardSuccessResponse: type: object description: | Standardized success envelope emitted by `sendSuccessResponse`. required: - success - data - timestamp properties: success: type: boolean enum: - true example: true data: type: object description: The operation payload. message: type: string description: Human-readable summary.
