Slack
If you want to have your dashboard subscriptions or alerts sent to Slack channels (or people on Slack), an admin must first integrate your Metabase with Slack.
Create your Slack App
For Metabase to post to your Slack channels, you’ll need to create a Slack App and make it available to Metabase.
From any Metabase page, go to Admin settings > Settings > Notification channels > Slack.
Click on Open Slack Apps. Metabase will open a new browser tab and send you over to the Slack website to create the Slack app.
On the Slack website, click Create an App.
Pick a workspace to develop your app
Select the workspace you want to create your app.
The app manifest
When you click on Open Slack App, Metabase will pass along the app manifest, which Slack will use to set up your app.
You may get a warning that says:
This app is created from a 3rd party manifest Always verify URLs and permissions below.
This warning is expected (Metabase is the third party here). You can click on Configure to see the app manifest Metabase sent along in the URL. Here is the manifest in YAML format:
_metadata:
major_version: 1
minor_version: 1
display_information:
name: Metabase
description: Bringing the power of Metabase to your Slack #channels!
background_color: "#509EE3"
features:
bot_user:
display_name: Metabase
oauth_config:
scopes:
bot:
- users:read
- channels:read
- channels:join
- files:write
- chat:write
- chat:write.customize
- chat:write.public
The manifest just take cares of some settings for your app and helps speed things along.
Click the Next button. Then hit Create to set up your Slack app.
Install your app to your workspace
On the Slack site for your newly created app, in the Settings > Basic Information tab, under Install your app, click on Install to workspace. On the next screen, click Allow to give Metabase access to your Slack workspace.
The Bot User OAuth Token
On the Slack site page for your Slack app, on the left in the Features section, click on OAuth and Permissions in the Slack Apps sidebar and then copy the Bot User OAuth Token. Return to the Slack settings page in your Metabase and paste this token in the Metabase field with the same name.
Create a channel in your Slack to store image files
In your Slack workspace, create a public channel named whatever you want — we think something like “metabase” does just fine — then enter that channel’s name in the Public channel to store image files field in Metabase. We’ll upload charts and tables here before sending out dashboard subscriptions. This allows your Metabase to post to your Slack workspace without having to deal with unnecessary permissions. Make sure the channel you create is the same channel that you enter in this field in Metabase (omit the “#” prefix).
If you rename the channel in Slack, you’ll need to update the Public channel to store image files in Metabase to that new name. This channel does not have to be the same as the channel where you send dashboard subscriptions. It’s only used for storing image files.
Save your changes in Metabase
In Metabase, click on the Save changes button and that’s it! Metabase will automatically run a quick test to check that the API token and your dedicated Slack channel are working properly. If something goes wrong, it’ll give you an error message.
Sending alerts and subscriptions to private Slack channels
In order to send subscriptions and alerts to private Slack channels, you must first add the Metabase app to the private channel.
In Slack, go to the private channel and mention the Metabase app. For example, if you called your Slack app “Metabase”, you’d just type @Metabase
. Slack will ask you if you want to invite your app to your channel, which you should.
Once your Metabase app is added to the private channel, you’ll need to type out the private channel’s name in the subscription or alert. Make sure to spell the channel’s name correctly, or Metabase won’t be able to send the notification.
