Hello,
l am new to mattermost and l find it lovely.
l want to use REST API to send direct message to a user.
When there is a direct message already opened, or had been opened with that user,
REST API works.
curl -i -X POST -d 'payload={"channel": "@[USERID]", "text": "
[MESSAGE]"}' http://[INCOMING WEBHOOK URL]
However, when there is no history of direct messaging with that user,
REST API failes with this return.
HTTP/1.1 307 Temporary Redirect

Thank you in advance.
