# Download the customer import template API Reference

Downloads the sample CSV that `POST /v1/companies/{company_id}/customers/imports` expects
with `source: csv`: the required headers plus example rows, separated by semicolons and written with a UTF-8 byte order mark
so that Excel opens it with the accents intact.

- **Example rows:** every one is importable as it stands — commas, quotes and accents
  included — so the template can be uploaded unchanged as a first test of the import.
- **Scope:** the file is the same for every credential and does not depend on any account
  or on any NIF.

### Authentication

Accepts any of:

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

### Responses

#### 200: CSV template downloaded successfully

**Headers:**

- `Content-Disposition` `string`: File name for download
- `Content-Type` `string`: File MIME type
- `Cache-Control` `string`: The file only changes when the import format does, so it may be kept for an hour. It is `private` and not `public` because the response is served under a credential: a shared cache must not hold it.

**Content `text/csv`:**

Type: `string` (binary)

**Example:**

```csv
nombre_fiscal;nif;email;telefono;direccion_calle;direccion_numero;direccion_codigo_postal;direccion_poblacion;direccion_provincia
"Construcciones García y Asociados SL";B12345674;contacto@construccionesgarcia.es;915551234;"Calle Gran Vía";45;28013;Madrid;Madrid
```

#### 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`
- **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": "FORBIDDEN",
    "message": "You do not have permission to access this resource"
  },
  "meta": {
    "timestamp": "2025-01-15T10:30:00Z",
    "request_id": "4bf92f3577b34da6a3ce929d0e0e4736"
  }
}
```

#### 429: Rate limit exceeded. `RATE_LIMIT_EXCEEDED` when the request rate of your credential is
over its limit; `TOO_MANY_REQUESTS` when an email the operation sends is held back because
too many went out to that recipient in a short time. Either way, retry after the
`Retry-After` seconds.

`QUOTA_EXCEEDED` is the other `429`: the operation would go over a quota of your plan
for the current period (issued invoices, for instance). Retrying does not help until the
quota resets or the plan changes. `error.details` carries `feature_code`,
`current_usage`, `quota_limit` and `reset_date`, and `RateLimit-Reset` the seconds until
the reset when it is known.


**Headers:**

- `Retry-After` `integer`: Seconds until the rate limit resets
- `RateLimit-Limit` `integer`: Maximum requests allowed in the window
- `RateLimit-Remaining` `integer`: Remaining requests in the current window
- `RateLimit-Reset` `integer`: Seconds until the current window resets

**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": "RATE_LIMIT_EXCEEDED",
    "message": "Too many requests. Please try again in 60 seconds."
  },
  "meta": {
    "timestamp": "2025-01-15T10:30:00Z",
    "request_id": "4bf92f3577b34da6a3ce929d0e0e4736"
  }
}
```

#### 500: Internal server error

**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")

- **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": "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")
- **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": "UNSUPPORTED_MEDIA_TYPE",
    "message": "Unsupported media type: text/plain. Supported: application/json"
  },
  "meta": {
    "timestamp": "2025-01-15T10:30:00Z",
    "request_id": "4bf92f3577b34da6a3ce929d0e0e4736"
  }
}

# Related Schema Definitions

## 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"})

## ResponseMeta

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