Roeshimi Unfortunately IFTTT is not really smart enough to do this automatically.
You need to setup a bunq_mutation trigger for every account, and then here is what I use for the action fields:
Account: the name of the account
Date: {{Date}}
Amount: {{Amount}}
Payee name: {{CounterpartyName}} ({{CounterpartyAccount}}) -> I prefer this one, but you can also e.g. only use CounterpartyName
Category: leave empty to use built-in YNAB categorization, I prefer to enter "Uncategorized" here, so I am forced to categorize every individual transaction
Memo: {{Description}}
Cleared: cleared -> this is the normal import behaviour
Approved: your own preference, I use false because I like to explicitly approve them
Flag color: none (for a generic import, unless you prefer otherwise)
Import Id: {{PaymentId}}
Anything between {{ and }} is copying a field from the trigger to the action.
