Connecting to Slack
Common Fate integrates with your Slack workspace using a private Slack application which you create and manage. This Slack app has a bot user OAuth token which is what we use to authenticate the application.
When Slack is connected, users will receive notifications when an incoming request needs approval, as shown below:
When an approver clicks on the "Approve" or "Close Request" buttons, they will be redirected to the web application to confirm their decision. Users who make requests will also receive notifications when the status of their request changes.
Prerequisites
Before you can setup the Slack integration you will need to have deployed the Common Fate application stack. You can verify this by running:
gdeploy status
A successful deployment will output the following:
[✔] Your Granted deployment is online
Setup instructions - Slack OAUth
Set up the Slack connection by running the following command:
gdeploy notifications slack configure
You will be prompted with an install link that is pre-populated with the required API URL.
Copy and paste this into the browser and follow the prompts to create the app from the manifest in your Slack workspace.
You will need to be an administrator of the Slack workspace to complete this process.
Once your Slack app is created, navigate to the OAuth & Permissions section of the menu and click Install to Workspace.
Once you have installed the app to your workspace, you will see a Bot User OAuth Token. Have this token ready for the next step.
The CLI will prompt you for the access token, Paste the token in and press Enter. You should see a success message indicating that Slack has been configured.
Finally, run the following command to push the change to your Common Fate deployment:
gdeploy update
You can test the integration by running:
gdeploy notifications slack test --email <your_slack_email>
This will send a test DM to this email.
Setup instructions - Slack Webhooks
Common Fate also supports a webhook notifier, using Slack Incoming Webhooks. This requires none of the read permissions that an OAuth installation requires.
Navigate to https://api.slack.com/apps and click Create New App > From Scratch. Give the app a name and select the workspace you wish to use it in.
You'll be met with a list of functionality you can add to your app. From the menu click Incoming Webhooks, Toogle the switch to Activate Incoming Webhooks and then "Add New Webhook to Workspace".
You'll be prompted to select a channel for the webhook to post to. Select the channel you want and click Allow.
You'll be redirected to the Incoming Webhooks page. Scroll to the Webhook URL section and click Copy.
To instead set up webhooks with gdeploy, run the following command:
gdeploy notifications slack-webhook configure -c <channel alias>
Where <channel alias> is an identifier for your webhook. We recommend using the name of the channel the webhook is configured to post to.
Finally, push the change to your Common Fate deployment with the following command:
gdeploy update
