# Send several invoices in one email API Reference Sends one email carrying the PDFs of several invoices of this company as attachments. - **`recipients`:** required, and must carry at least one address; no address is inferred from any profile. - **Limit:** up to 200 invoices per message (`invoice_ids`). - **Failures:** invoices whose PDF cannot be attached are reported in `failures`, and the message is still sent with the rest. ## POST /v1/companies/{company_id}/invoices/deliveries **Send several invoices in one email** Sends one email carrying the PDFs of several invoices of this company as attachments. - **`recipients`:** required, and must carry at least one address; no address is inferred from any profile. - **Limit:** up to 200 invoices per message (`invoice_ids`). - **Failures:** invoices whose PDF cannot be attached are reported in `failures`, and the message is still sent with the rest. ### Authentication Accepts any of: - `ApiKeyAuth` (HTTP bearer, token format `beel_sk_*`) ### Parameters - **company_id** (required) in path `string`: 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. - **Idempotency-Key** (optional) in header `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. | Status | Code | When | |---|---|---| | `400` | `INVALID_IDEMPOTENCY_KEY` | The key breaks the format rules above. | | `409` | `IDEMPOTENCY_KEY_PROCESSING` | The first request is still in flight. Wait for the `Retry-After` seconds (2) and retry with the same key. | | `409` | `IDEMPOTENCY_KEY_MISMATCH` | The key was already used with a **different** body. Use a new key. | ### Request Body Required. **Content `application/json`:** - **invoice_ids** (required) `array[UUID]`: No description - **recipients** (required) `array[Email]`: Email recipients. At least one is required: no address is inferred from any profile. - **cc** `array[Email]`: CC recipients. Copied addresses count as recipients of the message: they are subject to the same sending restrictions and to the same quota as the addresses in `recipients`. When omitted, the CC addresses configured in the sender's email defaults apply; send an empty array to deliver the message without any copy. - **subject** `string`: Custom email subject. Defaults to the standard template. - **message** `string`: Custom message body. Defaults to the standard template. - **language**: Email language. Defaults to the language of the requesting user. **Example `send_to_accountant`** — Send to accountant: ```json { "invoice_ids": [ "550e8400-e29b-41d4-a716-446655440001", "550e8400-e29b-41d4-a716-446655440002" ], "recipients": [ "accountant@example.com" ], "subject": "Invoices for January 2025", "message": "Please find attached the invoices from last month for your review." } ``` **Example `send_with_cc`** — Send with CC: ```json { "invoice_ids": [ "550e8400-e29b-41d4-a716-446655440001" ], "recipients": [ "accountant@example.com" ], "cc": [ "copy@example.com" ] } ``` ### Responses #### 200: Email sent successfully **Content `application/json`:** - **success** (required) `boolean`: No description (example: true) - **data** (required): The payload.

(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") #### 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: Your account does not own or manage this company, or does not hold the required access over it.

(example: "/v1/invoices/abc-123") #### 422: `VALIDATION_ERROR` — the body parses but a value is not acceptable. `details` is a flat map from the offending property's name (in the contract's `snake_case`, nested paths joined with a dot, e.g. `recipient.address.postal_code`) to a message describing what is wrong with it, one entry per property. When the rejected value is one outside an enum's vocabulary, `details` instead follows `FieldDeserializationError` (`field`, `invalid_value`, `allowed_values`). **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.

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 `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: "/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 ## CreateInvoiceDeliveryRequest One email delivery carrying several invoices of this company as attachments. - **invoice_ids** (required) `array[UUID]`: No description - **recipients** (required) `array[Email]`: Email recipients. At least one is required: no address is inferred from any profile. - **cc** `array[Email]`: CC recipients. Copied addresses count as recipients of the message: they are subject to the same sending restrictions and to the same quota as the addresses in `recipients`. When omitted, the CC addresses configured in the sender's email defaults apply; send an empty array to deliver the message without any copy. - **subject** `string`: Custom email subject.

Defaults to the language of the requesting user. ## UUID Universally Unique Identifier (UUID v4) Type: `string` (uuid) ## Email Email address (minimum valid email is 5 chars, e.g. a@b.co) Type: `string` (email) ## 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") ## 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"}) --- Full OpenAPI spec: https://docs.beel.es/api/openapi
