Get next document number preview

GET
/businesses/documents/next-number

Returns the next sequential document number for a specific document type. For display purposes only - does NOT increment the counter.

Authorization

X-Api-Key<token>

Business API key, e.g. vuz_ab12cdef... Created via Settings → Integrations → API Keys. Unlike partner keys, a public API key's STRING does not encode its environment — isolation instead comes from a completely separate sandbox database: a key minted on the Sandbox server (above) only ever reads/writes sandbox data and can never see or affect production, regardless of what the key looks like.
