hi folks - is there a way to download bank statements out of NetSuite, which were imported automatically through Bank Feed (standard feature)?

Not through SuiteQL or Saved Search unless that's changed recently. But, if you go to the Match Bank Data screen and pull up your dev console, you'll see it uses a non-public API the app uses to retrieve imported back transaction data. Here's an example of what the URL looks like. You could probably use it to retrieve the data you're looking for.

/erp/resources/importedtransactions.nl?accountId=931&isMatched=F&includeAutoPostStubs=F&sortBy=dDate&sortDirection=ASC&skip=2&includeDuplicates=F&isExcludedOrDuplicate=F

I was told by Partner support that its not possible

@eblackey But NetSuite doesn't expose a public endpoint for imported bank feed data. any further way

Correct. I think that's what I said above.

@eblackey To use non public api, you refering any tools?
