You know, you can save yourself a lot of time and effort by just using Google and doing some research first, before you ask the question.
If you had Googled “Jira Data Center REST API bulk get changelogs” you’d have seen how many times that question has been asked before, and the answer is still the same…. there is no equivalent bulk fetch issue changelogs API in the Jira Data Center product.
Or, just read the documentation for the Jira Data Center REST API directly, and see that there are no endpoints for bulk fetching issue changelogs.
