How to get the issue details for a project based on a Customfield value using REST API and/or JQL?

[Rajkumar Balakrishnan]

I would like to search for reported issue and its status based on a customfield value. Is it possible to do that with REST API and /or JQL?

First hit on my search engine returned the obvious - https://developer.atlassian.com/jiradev/jira-apis/jira-rest-apis/jira-rest-api-tutorials/jira-rest-api-example-query-issues

Last time when I checked the search engine, probably I missed entries on querying for issues something like: https://xxxxxx.atlassian.net/rest/api/latest/search?jql=project="SomeProject" AND customfield_10XXX ="SomeValue". My bad! Can you kindly point me to such an entry/discussion?

You've answered your own question.

I also thought it was a straight forward query. But, unfortunately it is not working. I was looking disparately looking for a clue on how to format the query to pull the issues for a project based on a customfield. I tired every combinaton possible for hours with no luck. I am simply able to pull issues based on all predefined searchable fields but not based on any of the customfields. I wanted to know what am I missing. I would very much appreciate if your could post a working example or guide me through.

Ok, try running the query you want in the UI, using the advanced search option so you have the plain text of the JQL you want.

This can be fed straight into the REST call to run the same query.

I figured out the solution. The query should be like: project= SomeProject AND text ~ "AA0000123"
