What api url can I use to get the most recent messages from a channel? I know I can use a outgoing webhook to get messages as they are sent but I would like to retrieve previous messages like the last 5 sent. Slack has a channel.history api method, however this did not seem to work here.
Documentation of the possible web service api urls would be really helpful. I checked the github logs and there doesn't seem to have been any progress here for 2 months.
