If you use fetch or XHR, yes.
If you just create an HTML form with the bank as action, fill in the inputs and submit via JS, no, because that's _navigating away_. This is also why GET requests that perform actions are dangerous, you can just embed them as an image to provoke a request. Which is exactly how zoom built their API. (they also then measured the size of the image to determine the response code, which is.... inventive)
