API

account_patterns

The account_patterns parameter is a list of (regex, account) pairs. For each line in your CSV, the Chase importer will attempt to create a matching posting on the transaction by matching the payee, narration, or the concatenated pair to the regexes.

The regexes are in priority order, with earlier patterns taking priority over later patterns.
