How to get xml of jira issues by api?

[Emma Aghlamazyan]

Hello,

We previously used the Jira XML export endpoint successfully:

/sr/jira.issueviews:searchrequest-xml/temp/SearchRequest.xml?jqlQuery=...

This endpoint worked for months without issues and returned the same XML that Jira UI exports.

As of recently, the exact same endpoint and the exact same JQL now return errors, even though:

• The JQL still works in the UI

• The project and issues still exist

• We are authenticated

• UI XML export still works

• Nothing changed on our side

• The URL structure is identical

Question:
Has Atlassian removed or changed support for the XML export endpoint (jira.issueviews:searchrequest-xml) in Jira Cloud?
If so, what is the new supported way to programmatically export issues in XML format using JQL?
