Post Message to a 'Private' Channel as flow bot

Would like to be able to send a flow bot message to a private channel.

Status: Under Review

Updating this Idea to 'Under Review'.

Not applicable

Hope this feature can be implemented soon, will be good to be able to send the approval card straight in the same channel

I've run into this roadblock also! I was surprised to find I couldn't send confidential Forms results to committee members in a private channel. Security is important, as is automation and ease of use.


Thanks for considering it!

Would be great if this was added, bit of a roadblock for our automation efforts.

Please add the ability to use adaptive cards and Flow Bot in private channels! This is a great use case for automation, but you might have an approval that should only be responded to by a portion of a team (e.g., management).

Yes. This is needed please. It's a waste to have to create another channel just to post messages.

Hi all, having just tested this, whilst the feature is not available as the flow bot, you can post messages to private channels as a user who is an existing member of said private channel.  There are two working actions as follows:






Please note, if you attempt to send a message as the flow bot you will receive an error:


Request to the Bot framework failed with error: '{"error":{"code":"BotNotInConversationRoster","message":"The bot is not part of the conversation roster."}}'.


Have fun 😀



P.S. take a look at my new blog here

I really wish FlowBot could post to private channels.  As a workaround, I've got a notification flow posting as myself.  This means everybody except me gets a notification about a change to a particular file set.  I've had to set up a parallel action to have FlowBot send me a chat notification.  This really shouldn't be necessary.

@DamoBird365 thank you - never thought of changing the 'Post As' to 'User'. Life saver, thank you!

This would be a great addition to the toolkit and seems like it would be an easy fix/win for the MSFT team. There are instances in which I need to post to a private channel as I have several different channels set up for different automated solutions that need to be restricted to one or more users.
