Fix Javascript

I hired someone to build a script to pull data from an API and populate it to a postgresql database. It works but he built one component incorrectly and I need it fixed ASAP. He is basically calling the API in a loop to get names from unique id but there's a method to pull all the names and ids in a single request to them populate a table in my database which could then be referenced to get the names from uniqueid. I can provide more details and the javascript file.
