I've been having the same problem using the Python API, and I suspect it doesn't expose this functionality. So here's my plan for testing this via curl or similar:
The GitLab API Docs page on Emoji Reactions has a section §Add reactions to comments that discusses emoji reactions to comments (aka notes). Below is a summary of that §.
It says that the form is supposed to be:
GET /projects/:id/issues/:issue_iid/notes/:note_id/award_emoji
^^^^^^^^^^^^^^^^^
Substitute merge_requests/merge_request_iid
or snippets/:snippet_id
as appropriate.
So,
curl --header "PRIVATE-TOKEN: <your_access_token>" "https://gitlab.example.com/api/v4/projects/1/issues/80/notes/1/award_emoji"
will return a json list of the emoji, and appending /:award_id
would retrieve a single one. For example:
curl --header "PRIVATE-TOKEN: <your_access_token>" "https://gitlab.example.com/api/v4/projects/1/issues/80/notes/1/award_emoji/2"
would return
