Is there a way to issue custom slash commands from bot messages?
Steps to reproduce
I created a custom slash command to perform GitLab-actions. It works just fine when I enter messages myself (like
/trigger issue new Testissue), but if that command is issued from a bot (in this case, through an incoming webhook from zapier), it just prints the command w/o doing anything.
I would expect the slash command to be performed, no matter where it comes from.
The command isn’t performed, but pasted as a normal message.
It is set up as a custom slash command already. The slash command itself is also working when entered directly - just not when entered by a bot. To me it seems that mattermost only looks for slash commands when messages are entered through the input field (before rendering them), and bot messages are rendered directly.
I would prefer to have an API to trigger slash commands over them being processed on normal messages sent through webhooks. I don’t want to have to bother with escaping such things (is that even possible right now?) when sending messages via the API.
IMHO slash commands are “in-band” for humans because having a separate edit box wouldn’t be convenient. But for bots they should very much be “out-of-band”.
Thanks @Herrner, appreciate your feedback and the use case.
Similar to the note from @ThiefMaster, it may be trickier for integrations to escape such things. It is also not clear what “/away” should do if posted by a bot.
That said, I’m wondering if there are other approaches to consider.
Is the flow something:
- Detect an event from a third-party service
- Post a notification in Mattermost
- Trigger a new issue based on the notification in step 2?
That’s the flow exactly. Zapier receives a specific E-Mail, posts that E-Mail as a bot to Mattermost and should use that post as a slash command to create an issue on GitLab.
I fail at using the API for that, too. I’m getting “No command trigger found”-errors for everything I try. If our GitLab only had incoming email enabled - I wouldn’t need any of that then.
Would you like to contribute this in the feature idea forum so it can be discussed, upvoted and considered for a help wanted ticket?
