Invoices

Apply one operation to a set of invoices

Scopeinvoices:write

Applies a single operation to up to 50 invoices of this company and reports, invoice by invoice, which succeeded and which failed.

Not atomic. Each invoice is processed in its own transaction: issuing is irreversible, so the ones already issued stay issued if a later one fails.

Downloading PDFs, sending email and exporting are not operations of this batch: each one returns something different and has its own sibling sub-resource (pdf-archive, deliveries, exports).

POST
/v1/companies/{company_id}/invoices/batches

Authorization

AuthorizationBearer <token>

API Key authentication.

Format: Authorization: Bearer beel_sk_<key>

Scopes: API Keys use the same scopes as OAuth2 tokens. Each key is created with specific scopes that limit which endpoints it can access. The required scope for each endpoint is documented in the operation's security section under OAuth2.

Obtaining Keys: API Keys are managed from the BeeL dashboard

Security: API Keys are secret credentials. Do not share them or store them in source code

In: header

Path Parameters

company_idstring

NIF (company) the operation acts on. 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 NIF you do not reach answers 403, and so does a NIF that does not exist, so the existence of a NIF in another account is never disclosed.

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)
  • If the same key is sent twice, the result of the first operation is returned
  • Keys 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 and retry with the same key.
409IDEMPOTENCY_KEY_MISMATCHThe key was already used with a different body. Use a new key.

Issue an invoice (DRAFT → ISSUED) POST

Finalizes a draft invoice of this company: assigns its definitive number from the configured series and makes it immutable. Irreversible — an issued invoice is corrected with a corrective invoice or voided, never edited. PDF and VeriFactu submission are asynchronous: a `200` means *accepted for submission*, never *registered with AEAT*.

Get an invoice of a company GET

Retrieves the full details of an invoice of this company (NIF).
