Hello
I tried to send email from api trough example code result is :

[to_email] => moha46@***.com
[to_name] => John Doe
[from_email] =>
[from_name] => Jane Doe
[reply_to_email] => hashemi@****.com
[reply_to_name] => Jane Doe
[subject] => This is the email subject
[body] => Hello world!

[priority] => 5
[retries] => 0
[max_retries] => 3

[status] => unsent
[date_added] => 2018-11-04 07:40:09
[last_updated] => 2018-11-04 07:40:09
at the backend in program logs I have got this log :
2018/11/04 07:35:10 [error] [exception.CHttpException.404] [195.201.12.83] exception 'CHttpException' with message 'امکان پاسخ به درخواست "transactional-emails/EMAIL-UNIQUE-ID" وجود ندارد' in /home/mailmain/public_html/apps/common/framework/web/CWebApplication.php:286

HttpException.404

404 = page not found
either
something is really missing
or
something is really inaccessible
hence, it could be just a matter of setting correct permissions
