I think you could use this api method: chat.getPermalink method | Slack. Not sure if you can invoke it with the “invoke Slack operation” or if you just need to send a plain api request.
As input you need the ts value of the message, which is a property of the message/reply objects.
Thanks, this is the simplest solution. Just as an extra note:
https://<workspace_name>.slack.com/archives/<channel_id>/<message_id>
The <message_id> section is just the timestamp field, which are returned by both Get Messages and Get Replies.
Thanks, I’ll try this out as well, although the below solution seems the simplest since we only need to use fields that we already know or that we are already gettign from Get Messages or Get Replies
