Slack Component

Send messages to Slack channels and users

Component key: slack

Changelog ↓

Description

Slack is a messaging platform. The Slack component allows posting messages to a Slack channel.

API Documentation

This component was built using the following API References:

Processing Slack events in real-time

Slack requires providing only one webhook URL for the app, and Slack will send all customers' events to that URL. To detect and process changes to customers' Slack accounts in real-time, see the Single-Endpoint Webhook Integrations guide on handling webhook requests from apps that require specifying a single webhook endpoint.

Connections

OAuth 2.0

key: oauth2

The vast majority of actions in this component use OAuth 2.0 for authentication.

Prerequisites

A Slack workspace with administrator access
Access to the Slack Developer App Portal

Setup Steps

Navigate to the Slack Developer App Portal
Click Create New App
Choose to create the app From scratch
Give the app a name and select the workspace. It will be configured to be multi-workspace capable in a moment
Select OAuth & Permissions from the sidebar
1. Under Redirect URLs, add https://oauth2.prismatic.io/callback.
2. At the bottom, add some User Token Scopes if the integration will send messages on behalf of users, or Bot Token Scopes if a Slack "bot" will send the messages. The scopes required depend on what types of things the Slack integration will need to do (create channels, send messages, etc). For sending messages to a channel as a bot, add these scopes: chat:write chat:write.public. To send messages as a user, see the section below.
Next, select Distribute App under Manage Distribution. Confirm that "removed hard coded information" is checked and select Activate Public Distribution. The app needs to be publicly distributed for installation in Slack workspaces.
Finally, open Basic Information. Copy the Client ID, Client Secret and Signing Secret.

Configure the Connection

Add a Slack step to the integration - that will create a connection config variable. Open the connection config variable.

Enter the Client ID, Signing Secret and Client Secret from the Slack app
For Scopes, enter the required scopes based on what Slack actions the integration includes:
- For sending messages to a channel, enter the scopes chat:write chat:write.public to assign 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 the Slack documentation.

Sending messages to private channels

The chat:write.public scope allows the bot to send messages to public channels. To send messages to private channels, or to be more selective about what channels the bot can send messages to, the bot must be invited 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, a not_in_channel error will be received from Slack when attempting to send a message to that channel.

Sending messages as a user

Slack applications typically send messages as bot users. To instead send messages as a user, edit the Auth URL and 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.

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

Dynamically changing the bot's name

The bot's username and icon are set when creating the Slack app. To override the bot's username within the integration, request the chat:write.customize scope in addition to chat:write.

GovSlack

Slack offers 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.

Input	Notes	Example
Authorize URL	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,channels:read,groups:read,im:read,mpim:read	https://slack.com/oauth/v2/authorize
Client ID
Client Secret
Is User	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.	false
Revoke URL	The OAuth 2.0 Revocation URL for Slack	https://slack.com/api/auth.revoke
Scopes (Bot)	A space-delimited set of one or more scopes to get the Bot token. If you want to access the API as a User, you must append a 'user_scope' query parameter to the end of the Authorize URL and set the 'Is User' flag to true.	chat:write chat:write.public users:read channels:read files:read files:write channels:manage channels:history groups:history mpim:history im:history
Signing Secret
Token URL	The OAuth 2.0 Token URL for Slack	https://slack.com/api/oauth.v2.access

Webhook URL

key: webhookUrl

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, these actions use Slack Incoming Webhooks.

Prerequisites

A Slack workspace with administrator access
Ability to create Slack apps in the workspace

Setup Steps

To generate a Slack incoming webhook URL:

Navigate to the Slack App Portal
Click Create New App, adding an app to the workspace
Under Add features and functionality select Incoming Webhooks
Activate Incoming Webhooks and then Add New Webhook to Workspace
Select the channel where messages will be posted
Copy the Webhook URL. It should be of the form https://hooks.slack.com/services/foo/bar/baz

Configure the Connection

Enter the Webhook URL into the connection configuration

Input	Notes	Example
Webhook URL	The Slack webhook URL. Instructions for generating a Slack webhook are available on the Slack component docs page.	https://hooks.slack.com/services/TXXXX/BXXXXX/XXXXXXX

Triggers

App Webhook

Trigger for handling slash command and modal webhooks from Slack | key: slashCommandWebhook

Input	Notes	Example
Content Type	The content type of the response returned to Slack.	text/plain
Response Body	The response body to return to Slack. Leave empty for no response body.

Events API Webhook

Receive and validate webhook requests from Slack's Events API for webhooks you configure. | key: webhook

Input	Notes	Example
Connection	The Slack connection to use.

Slack can be configured to send events to a workflow. This webhook trigger uses the Slack app's signing secret to verify requests from Slack.

This trigger automatically handles Slack's challenge verification, so no additional verification steps are required.

How It Works

This trigger routes incoming requests to one of three branches based on the request type:

URL Verify branch: Handles the initial challenge request when configuring the webhook in Slack. The trigger automatically responds with the proper challenge response.
Notification branch: Handles actual event notifications from Slack, such as when a channel is created or a message is posted.
Management branch: Handles requests from external systems for testing or management purposes. To invoke this branch, include the prismatic-bypass-challenge: true header in the request to bypass Slack message verification.

The trigger verifies all requests using the signing secret to ensure they originate from Slack.

Configuration

Configure the following input:

Slack Connection: The Slack connection containing the signing secret from the Slack app. This secret is used to cryptographically verify that webhook requests originate from Slack.

Event Types

Slack supports numerous event types that can trigger this webhook. Common events include:

Available Events (Examples)

Event	Description
`app_mention`	App was mentioned in a channel
`channel_created`	Channel was created
`channel_deleted`	Channel was deleted
`message.channels`	Message was posted in a public channel
`message.im`	Message was posted in a direct message
`user_change`	User profile information changed

Refer to Slack's Event Types documentation for the complete and up-to-date list of available event types.

Returned Data

The trigger returns different payloads depending on the branch:
