it should basically be possible to provide a request filter from a project. But it works only on one of the pre-liminary 7.2 releases or with a patch that ports it back to the 7.0 train: https://jira.axonivy.com/jira/browse/XIVY-2633https://jira.axonivy.com/jira/browse/XIVY-2633
The pre-liminary patch for 7.0 is also accessible here: https://answers.axonivy.com/upfiles/webserver.rest.extension.patch_1.0.0.201805241153.jar
