Request body
application/jsoncustomerIdstringRequiredContact external ID.
mode"PAYER" | "IDENTIFIED_PERSON" | "NON_PAYER"OptionalManually pinned VAT registration mode. PAYER = full VAT payer (21 %). IDENTIFIED_PERSON = §6i ZDPH: holds a DIČ for EU intra-community input VAT but does NOT charge output VAT. NON_PAYER = not registered for VAT. Setting this always sets source=MANUAL, which blocks the ARES cron from overwriting it.
releaseLockbooleanOptionalDrop the MANUAL lock and clear the pinned mode so the next ARES sync (within 4 hours) fills it back in.
