Setup Guide

You can find your Slack app credentials by visiting your Slack App dashboard.

You’ll need the following information to set up your Slack App with Paragon Connect:

• Client ID
• Client Secret
• Scopes Requested

​

Add the Redirect URL to your Slack app

Paragon provides a redirect URL to send information to your Slack app. To add the redirect URL to your Slack app:

1. Copy the link under “Redirect URL” in your integration settings in Paragon. The Redirect URL is:

https://passport.useparagon.com/oauth

2. Log in to your Slack App dashboard and select your Slack app.

3. In your Slack App page sidebar, navigate to OAuth & Permissions > Redirect URLs.

4. Press “Add New Redirect URL”.

5. Paste-in the redirect URL from Paragon. The redirect URL can be found in Step 1.

6. Press “Add”, then press “Save URLs”.

Slack provides you with the Client ID and Client Secret needed for the next steps after adding the redirect URL to your application. You can find the credentials under Basic Information > App Credentials in the Slack app sidebar.

7. Enable your Slack app in other workspaces. Under Settings > Managed Distribution > Share Your App with Other Workspaces, complete the listed steps to allow your Slack app to be installed by your customers.

​

Add your Slack app to Paragon

1. Select Slack from the Integrations Catalog.

2. Under Integrations > Connected Integrations > Slack > Settings, fill out your credentials from the end of Step 1 in their respective sections:

• Client ID: Found under Basic Information > App Credentials > Client ID on your Slack App page.
• Client Secret: Found under Basic Information > App Credentials > Client Secret on your Slack App page.
• Permissions: Select the scopes you’ve requested for your application. For a list of recommended scopes, please view this integration within your Paragon dashboard. View dashboard.

Press the blue “Connect” button to save your credentials.

Bot and user permissions in Slack

Slack offers two different versions of permission for your Slack App. Bot scopes give your app’s bot permission to perform actions like posting messages or reading channels, acting as the bot itself. User scopes on the other hand, let your app perform actions on behalf of a real user, like accessing private channels or user-specific data. Use bot scopes for general automation and user scopes when you need to act with a user’s privileges.

You’ll find the two categories in the OAuth & Permissions > Scopes section.

​

Specifying bot and user tokens

You can specify in Paragon the type of token permission you’d like to use based on the workflow, action, or API request.

1. Under Integrations > Connected Integrations > Slack > Settings, you can enable the toggle to use bot scopes only

2. While building Slack workflows an authorization option can be set for bot or user token

3. During a Proxy API request add a x-paragon-use-slack-token-type header as either user or bot

​

Connecting to Slack

Once your users have connected their Slack account, you can use the Paragon SDK to access the Slack API on behalf of connected users.

See the Slack REST API documentation for their full API reference.

Any Slack API endpoints can be accessed with the Paragon SDK as shown in this example.

// You can find your project ID in the Overview tab of any Integration

// Authenticate the user
paragon.authenticate(<ProjectId>, <UserToken>);

// Get All Channels
await paragon.request("slack", "/conversations.list", {
  method: "GET"
});

// Send Message to Channel
await paragon.request("slack", "/chat.postMessage", {
  method: "POST",
  body: {
    "channel": "YOUR_CHANNEL_ID",
    "text": "Hello, world",
    "as_user": true
  }
});

​

Building Slack workflows

Once your Slack account is connected, you can add steps to perform the following actions.

• Send message in channel
• Send DM
• Get User by Email
• Search Messages

When composing your Slack message, you can reference data from previous steps by typing {{ to invoke the variable menu.

Additionally, you can choose whether to send a message as a bot or your user. If you choose to send as a bot, you can choose to give your bot a custom name and icon.

​

Using Webhook Triggers

Webhook triggers can be used to run workflows based on events in your users’ Slack account. For example, you might want to trigger a workflow whenever new messages are created in Slack to sync your users’ Slack messages to your application in real-time.

You can find the full list of Webhook Triggers for Slack below:

• Direct Message Created
• Channel Created
• Direct Message Sent
• File Deleted
• Group Message Sent
• Channel Message Sent
• Direct Message Updated
• Group Message Updated
• Channel Message Updated
• App Mentioned
• New Message Reaction
• Message Reaction Removed
• Message Interaction

​

Subscribing to Slack Events

Paragon provides a request URL to subscribe your Slack app to events in Slack. To add the request URL to your Slack app:

1. In the Settings tab of your Slack integration in Paragon, copy the link under “Webhook URL”.

2. Log in to your Slack App dashboard and select your Slack app.

3. In your Slack App page sidebar, navigate to Event Subscriptions > Enable Events.

4. Provide the “Request URL.” Paragon will automatically respond to Slack’s challenge request and begin listening to events on behalf of your app.

5. Click Save Changes at the bottom of the Slack App dashboard.
