Full Description

Github integration for Mattermost

Inspired by mattermost-integration-gitlab this program creates a server using flask that listens for incoming GitHub event webhooks. These are then processed, formatted, and eventually forwarded to Mattermost where they are displayed inside a specified channel.

Join us in our Mattermost Channel


  • Python
  • Flask (install with pip install flask)
  • requests (install with pip install requests)
  • (optional) PIL (install with pip install pillow) - needed to hide big Github avatars


Copy config.template to and edit it with your details. For example:

USERNAME = "Github"
    'default' : ("", "off-topic"),
    'teamname/repositoryname' : ("", "repository-channel-id"),
    'teamname' : ("", "town-square"),
    'teamname/unimportantrepo' : None,
SECRET = 'secretkey'
    'hook': "/"
,   'address': ""
,   'port': 5000

GitHub messages can be delegated to different Mattermost hooks. The order is as
follows. First try to find a hook for the repositories full name. If that
fails, try to find a hook for the organisation name. Otherwise use the default
hook. Repositories can be blacklisted by setting them to None instead of
(url, channel).

The server is listening by default on address, port 5000, and
using / as base route.
Make sure to point your Github webhooks to

If you have a proxy/load-balancer in front of your machine, and do not want to
expose port 5000 to the outside, change the SERVER['hook'] value and redirect it
to this service.
For example, if SERVER['hook'] is /hooks/github, your Github webhooks
would be

If you don't want to use a secret set the field to None.

Start the server with python


This image is available on DockerHub

To run this, use the following docker-compose.yml while adjusting the settings for your own requirements:

version: '2'
    image: dynamictivity/mattermost-integration-github
      FLASK_DEBUG: 1
      MATTERMOST_WEBHOOK_CHANNEL: "mm-integration-github"
      - "5000:5000"

Deploying with Docker

To deploy with Docker, make sure you have Docker installed and run:

docker build -t mm-int-github .
docker run mm-int-github -p 5000:5000 -d

Supported Events

Not all Github events are forwarded to Mattermost. Currently supported events are:

  • Ping events (send when first adding the Github webhook)
  • Commit pushes and comments
  • Issues (open, close, comment)
  • Pull Requests (create, merge, remove, comment)
  • Create/Delete repositories
  • Create/Delete branches and tags

All other events will report back to GitHub with 400 Not Implemented.

Known issues

  • Channel names need to use the spelling that is used in their URL (the channel ID), e.g. instead
    of Town Square it needs to be town-square.

  • If you set a custom username (as shown in the default config), make sure you also set Enable webhooks and slash commands to override usernames under Custom Integrations in the System Console to True. Otherwise the bots username will be that of the person that setup the Mattermost integration.
