It'd be nice if besides slack we could also have pulses in Mattermost.

@robinfrick Do you have any experience with the Mattermost API? Is it a mostly 1-1 mapping of the Slack bot/slash command/app api structure? Would you be willing to do a bit of research to help us understand how much overlap there would be in the current way we post images to Slack with how we could post to Mattermost?

[tlrobinson]

FYI the Slack endpoints we currently use are:

• chat.postMessage - actually posts pulses with attached images
• users.list - list users for destination selection widget
• channels.list - list channels for destination selection widget
• channels.create - workaround for posting files, creates a hidden channel where we upload images
• rtm.start - start a streaming connection for MetaBot

[tlrobinson]

And yeah I think it would be super neat if we created a simple abstraction so it's easy for various messaging services to plug into Pulses + MetaBot, but we don't want to be stuck with the lowest common denominator either. Right now all we need is:

1. list users and channels where you might want to post your pulse to
2. post messages with attached images to any of those users or channels
3. for MetaBot, listen to a stream of messages on any/every channel and respond with text or pulses

But we might also want to do more in the future.

Ok as far as I can see it there is not an option for 1. The person setting up the pulse would have to type the channel name as Metabase wouldn't be able to get a list of channel/user names from mattermost. 2. & 3. look like they are supported.

For metabot:
The way integrations work on Mattermost is that you allow an integration to listen for keywords in a specific channel not everywhere at once. So that's another limitation.
http://docs.mattermost.com/developer/webhooks-outgoing.html

For pulses:
This should be better. The only limitation I see is that users have to type or copy-paste the channel names and there is no way of knowing whether it is correct without testing the pulse, so there is no immediate feedback.
http://docs.mattermost.com/developer/webhooks-incoming.html

When I wrote the request I wasn't aware of Metabot yet. I think Pulses should be relatively straight forward to adapt to Mattermosts API. I'm far from being a programmer, but I got a little bot that can post messages to mattermost up and running within very little time. I have never tried the same for slack so I can't judge, but according to mattermost's documentation at least the message format is the same. But as far as I can see it no one else +1'd my request yet so a) I can understand if you say it's not worth the effort if barely anyone wants it and b) having an incomplete experience compared to slack with metabot would probably rather raise more requests from users and possibly lead to disappointment rather than happy users.

I want to admit that Mattermost mimics to slack API. This means that current slack integration should just work, if you will allow changing a URL in it.

[paoliniluis]

@nosovk are you completely sure about this?
