Delete series

Deprecated. Use DELETE /v1/companies/{company_id}/series/{series_id}, which behaves identically.

Soft-deletes an invoice series. If the series is active, it is automatically deactivated before deletion.

• The code is NOT released: it stays taken even after deletion, because it identifies invoices already issued under it. Recreating a series with the same code returns 409 SERIES_CODE_DUPLICATED, so always pick a new code.
• Default series: it cannot be deleted while another active series of the same document type exists — promote that other one first. If it is the only series of its type, it can be deleted and the type is left with no series: a valid state in which issuing without an explicit series returns SERIES_DEFAULT_NOT_FOUND.
