Australian bank lookup via BSB, using Javascript

Question

Is there a means of looking up a bank name & branch through Javascript?

Perhaps an external service or an complete data-set that can be hosted internally and accessed through JSON?

Answer 1

You can buy a database of BSBs and load them into your database.

This is pretty good, but sometimes the list can be a little out of date. Also, the banks may close a branch and remove it from this master list of BSBs. However, transactions to that BSB will continue to work because they do a redirect to the new BSB.
