I am a non-engineer that has been dabbling in Oracle Application Express. My team has put together a great little program to help our workflow, but we're finding that it would be much more powerful if it could pull in data from our Bloomberg API. We currently use the Bloomberg API in Excel, but I have no idea how to implement it in Oracle Apex. Ideally, I would like a user to be able to enter a CUSIP into a field on their page, press a button, and return some real-time data from Bloomberg. I'm looking for someone to give me a chunk of code to drop into ApEx, and direction on where to drop it. Hopefully someone already has this completed, and this is a very easy job.
