Summary

As written in the below thread in the Atlassian Community, up until some time ago there used to be the api https://api.atlassian.com/pf-editor-service/convert?from=xxxx&to=xxx for converting Markdown, Markup, HTMl, etc  to Atlassian Document Format and vice-versa:

• Is there documentation for api.atlassian.com/pf-editor-service/convert?

By using this endpoint you could easily convert formats as described in below table:

This endpoint was not documented and therefore not supported stopped and it was decommissioned around the beginning of September. It would be nice to get an official endpoint customers can use to easily convert among formats.

Workaround

If you need to convert from ADF to HTML you can use the following workaround:

• To get the comment body returned as HTML call the GET /rest/api/3/[ISSUE KEY or ID]/comments endpoint and append ?expand=renderedBody to it:

  https://NAME.atlassian.net/rest/api/3/issue/{ISSUE-KEY_OR_ID}/comment?expand=renderedBody
  

• To get the issue description returned as HTML use the  /rest/api/3/issue/{issueIdOrKey}  endpoint followed by ?expand=renderedFields:

  https://NAME.atlassian.net/rest/api/3/issue/{ISSUE-KEY_OR_ID}?expand=renderedFields
