List Bank Account Transactions

Returns the transactions Bolta fetched from the bank, in the order they changed in Bolta. This is not transaction time order. Newly loaded or visible-again transactions come as ACTIVE. Transactions hidden from the dashboard come as REMOVED with only the id. The same id can arrive more than once, so apply items in the order you receive them: overwrite or delete by id.

hasMore can be true even when items is empty, so decide whether to continue from hasMore. The API fills nextCursor on the last page too. Save it and pass it on your next call to receive only the transactions that changed since then. Transactions changed in the last 5 minutes wait for a later call. You need a Standard plan or higher, and the call deducts no points. Bank account transactions guide
