So, we have Jira Software to keep track of our software bugs. We also have an in-house software with a REST API that tracks files and does some monitoring of new files coming in etc. One of its jobs is to keep track of the duplicate files that are stored in different paths in the hard disks. What i want is to implement an app that is triggered when a user is uploading a file in jira. At that time a rest api call should ask our other software if this file has duplicates and if it does inform the user (maybe with an alert box) that duplicates exist (maybe also show the paths of these duplicates). Can you give me some guidelines from where to start ?
