Requirement:

For some integration, it is required that the changelog endpoint itself always includes specified fields (even when they have not changed)

Please introduce an endpoint that always includes specified fields (even when they have not changed)

Workaround:

• The endpoint
  GET /rest/api/3/issue/{issueIdOrKey}/changelog
  is designed to return only the fields that actually changed in each changelog entry.

• Fields that did not change in a given history item will not be included in that specific changelog record.

For scenarios where you need to reliably read the current values of specific fields (such as status and “Delivery Area”), regardless of whether they changed at that moment, the recommended approach is to also call:

• GET /rest/api/3/issue/{issueIdOrKey}

• • https://developer.atlassian.com/cloud/jira/platform/rest/v3/api-group-issues/#api-rest-api-3-issue-issueidorkey-get

This endpoint returns the full current issue data, including all custom field values, so you can combine:

• the changelog (to know when changes happened), with

• the full issue data (to know the current values of all relevant fields).

This is the supported and recommended way to achieve this goal currently
