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!

@carlo.noelle,

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](https://developer.atlassian.com/cloud/jira/platform/rest/v3/#api-api-3-search-get) 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!
