NewStripe: a buyer with a NIF always gets a standard invoice, and the simplified threshold is deprecated

Proforma

Convert a proforma into an invoice

Scopeinvoices:write

Converts an accepted proforma of this company into a real invoice. The new invoice is created as a STANDARD draft linked back through source_proforma_id.

  • What converts: only proformas in status ACTIVE. One shown as EXPIRED is still ACTIVE underneath and converts too.
  • The proforma: preserved as the record of what the customer accepted — it keeps its PRO-... number and PDF and moves to the terminal status CONVERTED.
  • issue: with true the new invoice is numbered and issued in the same atomic call. If issuing fails nothing is created and the proforma stays ACTIVE. That includes 400 SERIES_NUMBER_COLLISION: the number the series would assign is already used by another invoice of the same company, and the series needs review, so contact support.
  • Errors: 422 CONVERSION_REQUIRES_PROFORMA when the document is not a proforma, 422 PROFORMA_NOT_CONVERTIBLE when it is not ACTIVE, and 409 PROFORMA_ALREADY_CONVERTED when it has already been converted — a second call never creates a second invoice.

Authorization

AuthorizationBearer <token>

Keys are prefixed beel_sk_, and each one carries the scopes it was created with: a key short of the scope an operation needs is answered 403. The scope an operation requires is shown next to its title, and the full catalogue lives in the Scopes reference.

Keys are created from the BeeL dashboard. They are secret credentials: do not share them or commit them to source control.

In: header

Path Parameters

company_idstring

Unique identifier (UUID) of the company the operation acts on — its identifier, not its NIF. It is the only source of context: the account that owns it is derived from it, and the BeeL-Active-Company header plays no part. A company you do not reach answers 403, and so does a company that does not exist, so the existence of a company in another account is never disclosed.

Formatuuid
invoice_idstring

Invoice ID

Formatuuid

Header Parameters

Idempotency-Key?string

Idempotency key to prevent duplicates in sensitive operations.

  • Any unique client-generated string (e.g. an order id). A UUID also works but is not required
  • Allowed characters: letters, digits, _ and - (max 255 chars)
  • Retrying with the same key replays the first response when it was a success (2xx) or a server error (5xx): same status and body, plus the header Idempotency-Replay: true. After a 5xx, check whether the operation took effect before retrying with a new key
  • A 4xx is not stored: the key is released, so the corrected request can reuse it
  • Stored responses expire 24 hours after processing

The key is scoped per user and environment, and bound to the request body, so retrying after a network timeout replays the stored response instead of repeating the operation.

StatusCodeWhen
400INVALID_IDEMPOTENCY_KEYThe key breaks the format rules above.
409IDEMPOTENCY_KEY_PROCESSINGThe first request is still in flight. Wait for the Retry-After seconds (2) and retry with the same key.
409IDEMPOTENCY_KEY_MISMATCHThe key was already used with a different body. Use a new key.
Match^[a-zA-Z0-9_-]+$
Lengthlength <= 255

Request Body

issue?boolean

If true, emit the resulting invoice atomically in the same act (assigns a fiscal number and runs the quota/ledger/VeriFactu→PDF flow). If false or omitted, the invoice is left in DRAFT.

Resume a paused recurring invoice (deprecated) POST

**Deprecated.** Use `PUT /v1/companies/{company_id}/recurring-invoices/{recurring_invoice_id}/status` with `{"status": "ACTIVE"}`, which behaves identically. Resumes automatic generation of a paused template. It keeps the scheduled next generation date whenever that date has not fallen due yet (including today), so resuming never re-issues a period you already invoiced and never undoes a skipped one. Only a date left in the past is rescheduled, to the first occurrence after today; the periods missed while the template was paused are not backfilled. **Retires on 9 December 2026.** See the [migration guide](https://docs.beel.es/changelog/resources-under-the-nif) for what moved where and what changes when you switch.

Convert a proforma into an invoice (deprecated) POST

Converts an accepted proforma into a real invoice. - **Deprecated:** use `POST /v1/companies/{company_id}/invoices/{invoice_id}/convert-to-invoice`, which behaves identically. - **Result:** the proforma moves to the terminal status `CONVERTED` and a new `STANDARD` invoice is created in `DRAFT`. - **Issuing:** `issue: true` numbers and issues that new invoice in the same call. **Retires on 9 December 2026.** See the [migration guide](https://docs.beel.es/changelog/resources-under-the-nif) for what moved where and what changes when you switch.
