OmniAuth Mattermost

This is the official OmniAuth strategy for authenticating to Mattermost. To use it, you'll need to sign up for an OAuth2 Client ID and Secret on the Mattermost Developer Page.

Installation

gem 'omniauth-mattermost'

Basic Usage

use OmniAuth::Builder do
  provider :mattermost, ENV['MATTERMOST_CLIENT_ID'], ENV['MATTERMOST_CLIENT_SECRET'], { client_options: { site: 'https://<instance-id>.mattermost.com' } }
end

Basic Usage Rails

In config/initializers/mattermost.rb

  Rails.application.config.middleware.use OmniAuth::Builder do
    provider :mattermost, ENV['MATTERMOST_CLIENT_ID'], ENV['MATTERMOST_CLIENT_SECRET'], { client_options: { site: 'https://<instance-id>.mattermost.com' } }
  end

Dynamic client_id and client_secret

In config/initializers/mattermost.rb

Rails.application.config.middleware.use OmniAuth::Builder do
  setup_proc = lambda do |env|
    req = Rack::Request.new(env)
    env['omniauth.strategy'].options[:client_options][:site] = req.params['site']
    env['omniauth.strategy'].options[:client_id] = req.params['client_id']
    env['omniauth.strategy'].options[:client_secret] = req.params['client_secret']
  end
  provider :mattermost, nil, nil, { setup: setup_proc }
end
