Request body

Schema: TransactionBulkUpdateCounterpartyRequest

transaction_idsarray · stringrequired: Array of transaction UUIDs to update.
counterpartystringrequired: Counterparty / merchant name to set on all selected transactions.
rememberboolean: When true, persist the rename as a per-business counterparty alias so it applies to future transactions too. Registry-linked transactions keep their registry link (the alias overrides the displayed name), and unlinked transactions get a name-keyed alias for their previous raw counterparty string. When false (default), behaves as a one-off rename of the selected rows.
