Invoices

Validate an invoice

Closes a draft invoice: checks compliance, assigns it a number against its series, signs it and locks it as immutable, all in the same transaction —no gaps and no double issuance—.

Generated from the schema

Fiscal document

This operation numbers the document against the fiscal series, signs it and locks it. Voiding keeps the number.

Not reversible

This operation cannot be undone.

Only from draft; from any other status it rejects the request without touching anything. It validates the document AS IT IS: composing it —lines, amounts, taxes— remains the job of the editor. A validated invoice is no longer edited: it is voided. It takes no body. It requires sales documents in the plan of the account (402 without it). Returns the full invoice, the same projection as its GET.

Authorizations

Bearer API key with the scope below. invoices:write

Headers

Idempotency-Keystring

Unique identifier of the request, chosen by the client (a UUID works). Between 1 and 255 characters: an empty header is rejected with 400 validation_error, because the client would believe itself protected. Repeating the same key with the SAME body within 24 h returns the stored response without executing again, with the Idempotent-Replay: true header. With a DIFFERENT body it returns 422. It is the safe way to retry after a network timeout.

Limits: min length 1, max length 255

Example:"9f1c2f4e-3a5b-4f6d-8e7a-0b1c2d3e4f5a"

If-Matchstring

Optimistic locking: the ETag you read from the resource (or *). If the resource changed since, the write is rejected with 412 precondition_failed before doing anything; read it again and retry. Without the header the write always proceeds.

Example:"\"3sT3d9pBvZq4h2N0w8x1YkLmQ7c\""

Errors

Status	Codes	Meaning
402	`addon_required`	The account plan does not include the add-on this operation needs; `requiredAddon` names it.
404	`not_found`	It does not exist or is outside the scope of the API key.
409	`conflict`	The current state of the resource prevents the operation, a request with that Idempotency-Key is already in progress, or another conditional write (`If-Match`) held the resource for more than five seconds. `errors[0].code` says which: `in_progress` and `lock_timeout` are solved by retrying; `invalid_state` is not, because the state of the resource forbids the operation.
412	`precondition_failed`	The `If-Match` entity tag does not match the current representation. Read the resource again and retry.
422	`idempotency_key_reused`	The same key was used before with a different body. Change the key.

401, 403, 429, 500 can be returned by any operation. Errors
