When I manually post to chatter and post a URL (video) I see a preview of the video, I don't get that when I do it via a flow/process - any ideas?
I need to be able to achieve this same preview when posting to Chatter via automation.
When you post manually to Chatter, it automatically detects url in the content of the post and creates a link message segment for that post. In order to achieve the same result, you need to create the link message segment in your flow/process. If you use Connect API to generate the post, this article has an example to do that.
