Summary

In the cloud, the Jira version doesn't really play any role as all sites are updated periodically by Atlassian. However, if you do have a use case that needs the Jira Cloud then you can follow the steps in this article.

Environment

Jira Cloud

Solution

To check the Jira Cloud version you can use the rest API endpoint /serverInfo to get the version and the build number details.

1. Open the Jira site in a browser

2. Edit the site URL to be in the below format and hit Enter

   https://<your-domain>.atlassian.net/rest/api/3/serverInfo

3. The result will be the JSON which will contain the versionNumber and buildNumber objects that gives the version and build details.
   

Please note, you should ignore the Version details from this endpoint. Jira Cloud's continuous development model means it doesn't use traditional versioning, instead relying on feature flags for functionality. Please follow below Feature request about removing the "version field" from the serverInfo API endpoint to prevent confusion, as it won't be updated.
