My company is developing an application that works with different QRadar versions (7.2.2, 7.2.3, 7.2.4). The REST api version is different on all 3 versions. We have some question about backward compatibility in general.
1. Is there a way to call the older API endpoint on a newer server? Something like /v1/ariel/searches on 7.2.4?
2. Is there a way to get the API or QRadar version number from the REST endpoint?
3. If the answer is no to 1, what's your recommendation for backward compatibility when the user upgrades QRadar from the API point of view? Our need is to export events data out of QRadar. Is there an exporter tool that's not as affected by API changes?
