Hi @Venkata Sagar Ganesh Rao Mahendrakar 

Which request are you trying to send? Just to change the Status field? I think what you are looking for is to transition the issue.

Try this request https://developer.atlassian.com/cloud/jira/platform/rest/v3/api-group-issues/#api-rest-api-3-issue-issueidorkey-transitions-post

If the above, which is for cloud, doesn't work then use the following:

/rest/api/2/issue/ISSUE_ID/transitions

Replace the ISSUE_ID with the eerr... issue id.

Then use the other one I gave you:

/rest/api/2/issue/ISSUE_ID/transitions
