REST API Create ticket we using for creating new tickets. But we need also possibility for customer to reply. REST API Send reply is not good as it reply to ticket not like customer as You cannot pass information who replied to ticket. What we meant we need to see in Redmine reply like this:
"Received from xxx@xxx.com"

We found REST API journal_messages.json in witch its possible to pass: {
"journal_message": {
"issue_id": "",
"content": "New replay to ticket 12"
"from_address": "",
"to_address": "",
"is_incoming": true
}
}

but parameter "is_incoming" not working. We see in DB there is column for this, and in code its hardcoded default value false
