Slack Component

Send messages to Slack channels and users

Component key: slack

Description#

The Slack component allows you to post messages to a Slack channel.

Slack Connections#

Slack OAuth 2.0#

The vast majority of actions in this component use OAuth 2.0 for authentication. To create a Slack OAuth 2.0 connection, first create and configure a Slack App by visiting the Slack Developer App Portal:

  1. Click Create New App
  2. Choose to create the app From scratch
  3. Give your app a name and select your workspace. We'll configure it to be multi-workspace capable in a moment
  4. Select OAuth & Permissions from the sidebar
    1. Under Redirect URLs, add https://oauth2.prismatic.io/callback as a redirect URL.
    2. At the bottom, add some User Token Scopes if you plan for this integration to send messages on behalf of customers, or Bot Token Scopes if a Slack "bot" will send the messages. What scopes you need is dependent on what types of things your Slack integration will need to do (create channels, send messages, etc). If you just need to send messages to a channel as a bot, add these scopes: chat:write chat:write.public. If you want to send messages as a user, see the section below.
  5. Next, select Distribute App under Manage Distribution. Confirm that you have "removed hard coded information" and select Activate Public Distribution. Your app needs to be publicly distributed for your customers to install it in their Slack workspaces.
  6. Finally, open Basic Information. Take note of the Client ID, Client Secret and Signing Secret.

Now it's time to configure your integration to use your Slack OAuth 2.0 app. Add a Slack step to your integration - that'll create a connection config variable for you. Open up that connection config variable.

Enter Client ID, Signing Secret and Client Secret that you noted before.

The Scopes that you need to enter depends on what Slack actions your integration includes:

  • If you're just sending messages to a channel, you can enter the scopes chat:write chat:write.public and that will assign you a bot token that can write messages to public channels. See below for information on sending messages to private channels.
  • Conversation and channel-related actions require admin.conversations:write.

Enter scopes with spaces in between them (e.g. chat:write users:read users:read.email).

A list of all Slack OAuth scopes and what each does are available in their docs.

Sending messages to private channels#

The chat:write.public scope allows your bot to send messages to public channels. If you would like to send messages to private channels, or would like to be more selective about what channels your bot can send messages to, your customer will need to invite the bot to specific channels.

If a bot does not have chat:write.public or tries to write to a private channel it's not a part of, you'll receive a not_in_channel error from Slack when you attempt to send a message to that channel.

Sending messages as a user#

Slack applications typically send messages as bot users. If you would instead like to send messages as a user, edit the Auth URL add chat:write to a user_scope query parameter on the Authorization URL to get a User token. To manage channels, add the channels:write scope.

Your Auth URL, then, will look something like this: https://slack.com/oauth/v2/authorize?user_scope=chat:write

Dynamically changing your bot's name#

Your bot's username and icon are things you set when you create your Slack app. If you would like to override your bot's username within your integration, you will need to request the chat:write.customize scope in addition to chat:write.

GovSlack#

Slack offrs GovSlack for government organizations that require compliance with FIPS 140-2, FedRAMP, ITAR, etc. To use the Slack component with GovSlack, change the beginning of OAuth auth URL, token URL, and revoke URL from https://slack.com to https://slack-gov.com. The component will automatically point API requests towards the Slack Gov API endpoint.

InputDefaultNotesExample
Input
Authorize URL
string
/ Required
Default
https://slack.com/oauth/v2/authorize
Notes
The OAuth 2.0 Authorization URL for Slack. If you want to request access to the API on behalf of a user, append a 'user_scope' query parameter to the end of the Authorize URL: https://slack.com/oauth/v2/authorize?user_scope=chat:write
Example
 
Input
Client ID
string

Default
Notes

Input
Client Secret
password
/ Required
Default
Notes
 
Example
 
Input
Is User
boolean
/ Required
Default
false
Notes
Flip the flag to true if you want to access the API as a user. If flipped you must also provide a 'user_scope' query parameter to the end of the Authorize URL. Leaving the flag false will grant you a bot token instead.

Webhook URL#

The Slack Message from Webhook and the Slack Block Message from Webhook actions are the only Slack actions that do not authenticate with OAuth. Instead, it uses Slack Incoming Webhooks. For your customers to use this authorization method, they will need to create their own Slack apps and incoming webhooks.

To generate a Slack incoming webhook URL:

  1. Navigate to https://api.slack.com/apps
  2. Click Create New App, adding an app to your workspace.
  3. Under Add features and functionality select Incoming Webhooks
  4. Activate Incoming Webhooks and then Add New Webhook to Workspace
  5. Take note of the Webhook URL. It should be of the form https://hooks.slack.com/services/foo/bar/baz
InputNotesExample
Input
Webhook URL
string
/ Required
Notes
The Slack webhook URL. Instructions for generating a Slack webhook are available on the Slack component docs page.

Slack Events API Webhook#

Trigger for handling webhooks from Slack's events API | key: webhook

InputNotes
Input
Connection
connection
/ Required
Notes
The connection to use

You can configure Slack to send events to a Prismatic integration. This webhook trigger uses your Slack app's signing secret to verify that messages come from Slack. If a challenge request is received, this trigger responds with the proper challenge response and this trigger follows the "URL Verify" branch. For other notifications, like a "channel create" event occurred, this trigger follows the "Notification" path.

If you would like to invoke a flow that uses a Slack webhook trigger from an app other than Slack, you can send an additional header, prismatic-bypass-challenge: true with your request, to bypass Slack message verification. When that header is present your integration will follow the "Management" branch.
