Is it possible to edit the existing jira api ?

[Jonnada Kiran]

We are experiencing performance issues when user gives a empty jql and click search. I want to prevent user from doing this. What I am thinking is to edit rest/issueNav/1/issueTable this rest api and check if jql is empty then I want to send a empty JSON instead of all issues. Is it possible ?

Hi, you can implement servlet-filter for the specified url-pattern to check if jql is empty and form the desired response.

How to do it ?

You need to implement plugin with servlet-filter module: https://developer.atlassian.com/server/jira/platform/servlet-filter/
