Search API works in one Jira Cloud instance but not in another

Question

We have two Jira Cloud instances. In one instance, the following API works properly: /rest/api/2/search?jql=project={project}&maxResults=100&fields=*all,-comment,-worklog,-issuelinks,-subtasks,-attachmentHowever, in the second instance the same API does not work. Could you please clarify why there is a difference in behavior between the two Jira Cloud instances?

Hi @sarvesh - as already discussed in one of your earlier posts, the Search endpoints are deprecated. See: https://developer.atlassian.com/changelog/#CHANGE-2046 - Your instance admin (or you) also got an email about this, also clarifying about the deprecation date, etc.

Not all Jira instances always have the same feature status. Most features and changes are rolled-out in waves. Therefore you might see the endpoint still working in one environment, but this will soon stop working as well.

Hi @sarvesh

This API endpoint is deprecated and is actively being removed from instances by Atlassian.

See; https://developer.atlassian.com/changelog/#CHANGE-2046

New API endpoint is: https://developer.atlassian.com/cloud/jira/platform/rest/v3/api-group-issue-search/#api-rest-api-3-search-jql-get
