Rules are applied to matching transactions based on the specified filters. At least one filter must be specified (merchant_type_filter, transaction_description_filter, counterparty_filter, bank_transaction_type_filter).

​
Applying categorization rules retroactively

The rule can optionally be applied retroactively to existing uncategorized transactions via the apply_retroactively flag. If apply_retroactively is true, the rule will be applied to existing uncategorized transactions when the rule is created. If false, the rule will only apply to future matching transactions and the preview is informational only.
