Hi there. When I was developing Slacker the idea was to replicate Slack API by keeping the same method signature including method names and parameters, so it remains consistent with the Slack API. We just pass given parameters without too much modification. I think the safe bet is to pass channel IDs instead of names as channel name is not supported across all Slack API endpoints.

This is still broken, and should work with channel name without # as per documentation:

As long as the authenticated user is a member of the private group, you can either pass the group's name (secret-group) or encoded ID (G012AC86C), and the message will be posted to that group. The private group's ID can be retrieved through the groups.list API method.
