# Get default series status per document type (deprecated) API Reference

**Deprecated.** Use `GET /v1/companies/{company_id}/series/defaults`, which behaves
identically.

Reports, for each `DocumentType` used by automatic invoicing, whether there is a default
invoice series and which one: `exists`, plus the `series_id` when there is one.

- **Why check it:** a document type with no default series makes an incoming charge be
  skipped with `failure.payment.skip.missing_default_series` instead of invoiced.
- **Environment:** test or production is resolved automatically from your request context;
  no input needed.

**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.

### Authentication

Accepts any of:

- `ApiKeyAuth` (HTTP bearer, token format `beel_sk_*`)

### Responses

#### 200: Default series status retrieved successfully

**Content `application/json`:**

- **success** (required) `boolean`: No description (example: true)
- **data** (required): The payload. An object for a single resource; an object holding the named collection (and its `pagination`) for a listing. Never a bare array at this level in v1.
- **meta** `ResponseMeta`
- **data** `object`: No description
  - **defaults** (required) `array[DocumentTypeDefaultStatus]`: No description

#### 401: Missing or invalid authentication. Like every other error, `message`/`detail` is
localized according to `Accept-Language` (`es`, `en`, `ca`); defaults to English when the
header is missing or asks for none of those.


**Content `application/json`:**

- **success** (required) `boolean`: No description (example: false)
- **error** (required) `ErrorDetail`
- **meta** `ResponseMeta`
- **type** `string` (uri): Stable URI that identifies the problem type and where the integrator will find its documentation. (example: "https://docs.beel.es/errors/INVOICE_NO_LINES")
- **title** `string`: Short summary of the problem type. Stable between occurrences of the same `type`. (example: "INVOICE_NO_LINES")
- **detail** `string`: Specific message for this occurrence, localized according to `Accept-Language` (`es`, `en`, `ca`); defaults to English. Matches the legacy `error.message`. (example: "The invoice must have at least one line")
- **instance** `string` (uri-reference): URI that identifies the specific occurrence of the problem — typically the path of the affected resource. (example: "/v1/invoices/abc-123")

**Example:**

```json
{
  "success": false,
  "error": {
    "code": "UNAUTHORIZED",
    "message": "Authentication is required to access this resource"
  },
  "meta": {
    "timestamp": "2025-01-15T10:30:00Z",
    "request_id": "4bf92f3577b34da6a3ce929d0e0e4736"
  }
}
```

#### 403: Authenticated but not allowed. Fourteen causes shared by every operation, told apart by
`error.code`; an operation that adds a cause of its own names it in its `403`. You can
branch on them exhaustively.

- `INSUFFICIENT_SCOPE` — the credential lacks a scope the operation requires;
  `error.details.missing_scopes` names them as a single comma-separated string (for
  example `"invoices:write,customers:read"`), not as an array; `required_scopes` has the
  same shape and lists every scope the operation needs. Retrying will not help: mint a key
  that holds them.
- `COMPANY_READ_ONLY` — the scope is there, but your access level over that NIF only
  lets you read it.
- `ACCOUNT_MANAGEMENT_FORBIDDEN` — the scope is there, but your role over the account,
  or the management relationship you hold over it, does not cover this operation.
- `ACCOUNT_NOT_ACCESSIBLE` — the account is not yours to reach, which is also the answer
  when it does not exist, so existence is never disclosed.
- `ACTIVE_COMPANY_NOT_ACCESSIBLE` — the same, for a NIF: the company in the path, or the
  one named by `BeeL-Active-Company`, is not one this credential may reach — and again,
  this is also the answer when it does not exist.
- `COMPANY_ACCESS_REVOKED` — your access to the NIF was withdrawn while the request was
  already in flight, so the write was rejected and nothing was recorded. Retrying will
  not help until the access is granted again.
- `LIVE_CREDENTIAL_REQUIRED` — the operation changes the real account and the call came
  from a test API key (`beel_sk_test_…`). Use your live key or the dashboard.
- `FEATURE_NOT_AVAILABLE` — your subscription does not include the entitlement the
  operation needs; `error.details.feature_code` names it. This gate runs **before** the
  scope gate, so for such an operation you never see `INSUFFICIENT_SCOPE` first.
- `NO_ACTIVE_ACCOUNT` — the credential does not resolve to an account, so no scope can be
  evaluated against one. Fail-closed, not a permission that can be granted to you.
- `OPERATION_REQUIRES_SESSION` — the operation is available only from the web session; no
  API key and no OAuth2 token can perform it, whatever scopes it holds.
- `OPERATION_REQUIRES_API_KEY` — the reverse: the operation needs a scope that only an API
  key can hold (such as `accounts:write`), so a dashboard session never satisfies it.
- `API_KEY_LIVE_NOT_AVAILABLE` — the call came with a live API key (`beel_sk_live_…`) and
  the account has no Live mode yet. It is never degraded to Test: use your test key, or
  activate Live first.
- `ACCOUNT_REQUIRES_FOCUS_SWITCH` — dashboard session only: you are a member of the account
  in the path, but it is not the account in focus. Switch focus to it and retry.
- `REQUEST_BLOCKED` — the edge security filter stopped the request before the API saw its
  body, usually because a text field carries something that looks like markup or a
  script (HTML tags, `<script>`). Review the body and retry.


**Content `application/json`:**

- **success** (required) `boolean`: No description (example: false)
- **error** (required) `ErrorDetail`

- **type** `string` (uri): Stable URI that identifies the problem type and where the integrator will find its documentation. (example: "https://docs.beel.es/errors/INVOICE_NO_LINES")
- **title** `string`: Short summary of the problem type. Stable between occurrences of the same `type`. (example: "INVOICE_NO_LINES")
- **detail** `string`: Specific message for this occurrence, localized according to `Accept-Language` (`es`, `en`, `ca`); defaults to English. Matches the legacy `error.message`. (example: "The invoice must have at least one line")
- **instance** `string` (uri-reference): URI that identifies the specific occurrence of the problem — typically the path of the affected resource. (example: "/v1/invoices/abc-123")

**Example:**

    "request_id": "4bf92f3577b34da6a3ce929d0e0e4736"
  }
}
```

{
  "success": false,
  "error": {
    "code": "INTERNAL_ERROR",
    "message": "Internal server error"
  },
  "meta": {
    "timestamp": "2025-01-15T10:30:00Z",
    "request_id": "4bf92f3577b34da6a3ce929d0e0e4736"
  }
}
```

#### default: Any status code the operation does not list above. Every operation declares it, so a
generated client always has a branch to fall into and never loses the cause of a failure
it did not anticipate.

This is where the transport-level answers land — `405`, `406`, `415` and `429` — together
with any status a future version of the API starts returning. All of them carry the same
error envelope as the codes listed explicitly, so `error.code` is what tells them apart:
switching on the status code alone is not enough. See «Transport-level errors» in the
API description for when each one is produced.

A `402` carrying `SUBSCRIPTION_REQUIRED` lands here when the account has no active
subscription. `error.details` says why and what to do: `current_status` (absent if it
never had one), `required_permission` and `action`.

A `503` carrying `SERVICE_UNAVAILABLE` lands here too, with a `Retry-After` header: a
dependency of BeeL itself (the database, the email provider) was momentarily
unavailable and nothing was done. Retry after those seconds.

A `502` carrying `EXTERNAL_SERVICE_ERROR` also lands here: an outbound integration the
operation depends on failed or did not answer in time. It is a transient condition — retry
with the same `Idempotency-Key` where the operation accepts one.

One exception to the envelope: a failure of the network edge that never reaches the
application (`502`, `503`, `504`, `524`) is generated by Cloudflare and its body is not
BeeL's — it may not even be JSON. Treat those as "no answer", and retry.


**Content `application/json`:**

- **success** (required) `boolean`: No description (example: false)
- **error** (required) `ErrorDetail`
- **meta** `ResponseMeta`
- **type** `string` (uri): Stable URI that identifies the problem type and where the integrator will find its documentation. (example: "https://docs.beel.es/errors/INVOICE_NO_LINES")

# Related Schema Definitions

## SuccessResponse

The envelope every successful JSON response of the BeeL. API is wrapped in. There are no
bare resources in v1 and none are planned: the payload always hangs off `data`.

- A **single resource** is an object in `data`.
- A **collection** hangs off a named key inside `data`, together with its `pagination`,
  also inside `data` — `data: {invoices: [...], pagination: {...}}`.
- A collection carries `pagination` unless its operation declares itself a **closed
  catalogue**: a fixed, bounded list with nothing to page through. The declaration is
  explicit in the operation; a missing `pagination` is never something to infer.
- `GET /v1/accounts` pages by cursor (`data: {accounts: [...], next_cursor}`). It is a
  documented variant of pagination, not another envelope.

Putting the array straight into `data` with `pagination` as its sibling is the shape a v2
would adopt; v1 is not being flipped to it.

- **success** (required) `boolean`: No description (example: true)
- **data** (required): The payload. An object for a single resource; an object holding the named collection (and its `pagination`) for a listing. Never a bare array at this level in v1.
- **meta** `ResponseMeta`

## ResponseMeta

- **timestamp** `string` (date-time): No description (example: "2025-01-15T10:30:00Z")
- **request_id** `string`: No description (example: "4bf92f3577b34da6a3ce929d0e0e4736")

## DocumentTypeDefaultStatus

Status of the default invoice series for a single `DocumentType` in the
request's environment (resolved via auth context, no input needed).

When `exists` is `false`, `series_id` and `code` are absent. The integration
setup screen reads this list to surface missing defaults at config time
instead of failing webhooks at runtime with `MISSING_DEFAULT_SERIES`.

- **document_type** (required) `DocumentType`: Document type associated with a series. Values mirror `InvoiceType`, so the series a document needs is named exactly like the document: - UNASSIGNED: Legacy value of series created before types existed. A series numbers only documents of its own type, so an `UNASSIGNED` series numbers none (`422 SERIES_INCOMPATIBLE_DOC_TYPE`); give it a type to keep using it. No series can be created with it or moved to it (`422 SERIES_UNASSIGNED_TYPE_NOT_ALLOWED`). The live ones were given the type they numbered most. - STANDARD: Standard invoice - SIMPLIFIED: Simplified invoice - CORRECTIVE: Corrects or cancels a previous standard invoice (R1–R4) - SIMPLIFIED_CORRECTIVE: Corrects a simplified invoice (R5). Spanish law requires R5 to be numbered apart from R1–R4, so they have a series type of their own - PROFORMA: Proforma (commercial document, non-fiscal numbering)
- **exists** (required) `boolean`: Whether the user has a default series for this document type.
- **series_id** `string` (uuid): ID of the configured default series (only when exists=true).
- **code** `string`: Code of the configured default series (only when exists=true).
- **provisional** `boolean`: Whether the default series is still **provisional**: it exists but has not issued any invoice yet, so its numbering (`initial_number`) can still be changed. The invoice creation screen uses this to warn that numbering will start at 1 before it is too late — once the first invoice is issued the numbering is frozen and `initial_number` can no longer be updated. Always `false` when `exists` is `false`.

## ErrorResponse

Error response shared by all BeeL. APIs.

The payload carries **two contracts at once** (additive, non-breaking):

- **Legacy** (`success`, `error.{code,message,details}`, `meta`) — kept
  intact for existing consumers.
- **RFC 9457** (`type`, `title`, `detail`, `instance`) — new fields
  for integrators following Problem Details for HTTP APIs. The
  `type` URI is the stable, shareable link to the error's
  documentation page (e.g. `https://docs.beel.es/errors/{code}`).

Future migration: the legacy fields will be deprecated via
`Deprecation`/`Sunset` headers after a sufficient adoption window,
and the response Content-Type will move to
`application/problem+json`.

- **success** (required) `boolean`: No description (example: false)
- **error** (required) `ErrorDetail`
- **meta** `ResponseMeta`
- **type** `string` (uri): Stable URI that identifies the problem type and where the integrator will find its documentation. (example: "https://docs.beel.es/errors/INVOICE_NO_LINES")
- **title** `string`: Short summary of the problem type. Stable between occurrences of the same `type`. (example: "INVOICE_NO_LINES")
- **detail** `string`: Specific message for this occurrence, localized according to `Accept-Language` (`es`, `en`, `ca`); defaults to English. Matches the legacy `error.message`. (example: "The invoice must have at least one line")
- **instance** `string` (uri-reference): URI that identifies the specific occurrence of the problem — typically the path of the affected resource. (example: "/v1/invoices/abc-123")

## ErrorDetail

- **code** (required) `string`: No description (example: "VALIDATION_ERROR")
- **message** (required) `string`: No description (example: "The provided data is not valid")
- **details** `object`: No description (example: {"field":"specific error message"})

## DocumentType

Document type associated with a series. Values mirror `InvoiceType`,
so the series a document needs is named exactly like the document:
- UNASSIGNED: Legacy value of series created before types existed. A series numbers only
  documents of its own type, so an `UNASSIGNED` series numbers none
  (`422 SERIES_INCOMPATIBLE_DOC_TYPE`); give it a type to keep using it. No series can be
  created with it or moved to it (`422 SERIES_UNASSIGNED_TYPE_NOT_ALLOWED`). The live
  ones were given the type they numbered most.
- STANDARD: Standard invoice
- SIMPLIFIED: Simplified invoice
- CORRECTIVE: Corrects or cancels a previous standard invoice (R1–R4)
- SIMPLIFIED_CORRECTIVE: Corrects a simplified invoice (R5). Spanish law requires R5 to be
  numbered apart from R1–R4, so they have a series type of their own
- PROFORMA: Proforma (commercial document, non-fiscal numbering)

Type: `string` — one of: UNASSIGNED, STANDARD, SIMPLIFIED, CORRECTIVE, SIMPLIFIED_CORRECTIVE, PROFORMA
