API to Fetch Latest Firmware for PowerEdge R740 via OpenManage Enterprise

Hi, I'm building a Java Spring Boot API to manage firmware for a Dell PowerEdge R740. I can fetch the installed firmware version using iDRAC credentials and cURL, storing data in a database (model_name, installed_firmware_version, latest_firmware_version, is_update_available). I need to fetch the latest firmware version using Dell OpenManage Enterprise (OME) API.

Questions:

How to set up OME and create a catalog with POST /api/UpdateService/Catalogs?

Sample request for GET /api/UpdateService/Catalogs(<catalog_id>)/FirmwarePackages to get latest versions?

How to parse the response for BIOS/iDRAC versions?

Any alternative APIs if OME isn’t ideal?

Please share code snippets or documentation links. Thanks!
