Hello,
i am writing a custom app that uses Jira’s Rest API to search for Issues.
I am able to search after issues using a JQL Query, but i can’t find a way to validate the Query like the searchbar in Jira itself can do.
Do you know a way i can accomplish that in my custom app?
Thanks!
I think you are looking for a JQL auto-complete feature and I’m not aware how to implement it.
If you would only want to validate if is this a valid JQL you can check for the
Search REST AṔI response code. If the it return 400 it means that the JQL query is invalid and you can display a message to end user.
I hope someone from community can assist you with the auto-complete part 
Cheers
Hello @italo.qualisoni !
Your solution is great! I was hoping for some validator function that i can implement directly in my code to reduce ajax calls, but i will live with the cost… 
Thanks!
Great that it helped! Can you make my previous comment as solution for this question?
Cheers
Yes sorry it took so long
