Frequently Asked Questions

How can I find the right channel?

List your visible teams and the selected team’s public channels. Use the channel ID for reading or posting.

Can I reply to an existing thread?

Yes. Provide the channel ID and root post ID and ask to send a reply to that thread. Without a root post, the action creates a new channel post.

Can I focus a summary on recent posts?

Yes. Provide a start date and time with the time zone, or use a selected post as the boundary for the review.
