This plugin provides a Moodle message provider for Slack.

It requires a Slack App be set up in the team, using Once created, the basic information screen for that
App will show the Client ID and the Client Secret required for the Moodle plugin configuration.

This is setup so that "only one" Slack Team can be set up at the site level. Anyone wishing to have a Slack notification setup
for their Moodle account must be a member of that team and use their account for that team.

The user connection is done via the Slack button, which uses the OAuth 2.0 protocol in Slack (

Full setup documentation for bot the plugin and users can be found here -

If the user logs into a different team Slack when trying to connect Moodle, they will receive the error:
"OAuth Error: invalid_team_for_non_distributed_app".
If the user is already logged into a different team Slack when trying to connect Moodle, they will receive the team login screen
for Slack until they do login to the correct Slack.
I am trying to determine if there is a way to "force" the login to the correct team.

If you wish to contribute in any way, message me on github or to

Future thoughts:
- It may be possible to allow users to pick their own teams, but it would involve the same complex setup for each user as it is
for the site setup.
- It would be great if the current configuration forced the team set at the site level so that the user account connection is
- It would also be great if the connection to Slack could use the Slack user's user name to set the channel rather than force the
user to pick one.

    Hi Mike, congratulations for the idea. Unfortunately I don't know how I can setup/test this in my moodle. Is there any step-by-step guide? Thanks

    I still haven't written the step by step instructions, since this is still very Beta. But, the readme file and the description above should be enough to get you started. You essentially need to be a Slack admin of your Slack team, create the Slack app using the link in the readme, and the use the client id and secret that are generated from that app to configure Slack at the site level.
    Each uses then only needs to use the "Slack button" on their notifications preference screen to connect their Slack account.

    Hi Mike!

    I will love to have this plugin on my moodle, but my version is 3.5.1. Please let me know if your release version could work? or if you have planned to release a new version for moodle 3.5.

    Although I haven't tried it, it should work on 3.5 as well.

    Great idea, would love to explore this more. We're on moodle 3.8. Do you know if this works for this version?

    Awesome Plugin! I installed and worked around, its super neat!

    But i needed to know if we can add custom messages to the notification. The current notifications are too dirty for user consumption. Could you guide me with that?

    Hey, guys! How's it going?

    I managed to get the plugin running and even notifying in slack, but I actually need it to notify when a new course is available.

    Sadly, that doesn't look as an option in notification preferences, am I unfortunately correct?

    Hi Everyone,
    After setting up Slack and the Notification Preferences, the Slack column does not have switch buttons (for both online or offline) to toggle notifications on and off. It only says "Disabled" instead.
    Does anyone know how to fix this? Thank you.
