Delivery notes

Convert delivery note to invoice

Convert a delivery note into a sales invoice. The delivery note moves to `invoiced` with `converted_to_id` populated and the new invoice is returned under `data`. Only `target=invoice` is supported.

Authorization

Path Parameters

delivery_note*string

Header Parameters

Idempotency-Key?string

Unique key generated by the client to ensure idempotency on retries. It lets you safely resend the same request: the first response is cached and returned without re-executing the mutation. It is an opaque string to the server; any unique value of up to 64 characters is valid (UUID v7, UUID v4, ULID, nanoid, etc.). UUID v7 is recommended for consistency with the API identifiers. The same key reused with a different body returns 409 idempotency_key_reused.

Length1 <= length <= 64

POST

Cancel a delivery note

Transition a delivery note to the `cancelled` state. Canonical REST replacement for the deprecated `POST /change_status`. Returns 409 `invalid_status_transition` if the note cannot be cancelled (e.g. already invoiced). Supports `Idempotency-Key` for safe retries.

POST

Create a delivery note

Create a new delivery note (albarán) in `draft` status. Delivery notes track goods shipped to a customer and can later be converted to invoices.
