Slack Bot Overview#

The Slack Bot API allows you to build rich, interactive bots for Slack workspaces. These bots can respond to messages, post updates, and interact with users in various ways. With the Slack Bot API on Pipedream, developers can create automated workflows that trigger on specific events in Slack, such as new messages or reactions, and then perform defined actions, like sending data to other apps or processing the information within Pipedream's serverless platform. This tight integration with Pipedream enables both simple and complex automations, leveraging Pipedream's ability to connect with numerous apps and its powerful built-in code steps.

Trigger Configuration#

This component may be configured based on the props defined in the component code. Pipedream automatically prompts for input values in the UI and CLI.

Label	Prop	Type	Description
Slack Bot	`app`	`app`	This component uses the Slack Bot app.
N/A	`db`	`$.service.db`	This component uses `$.service.db` to maintain state between executions.
Polling schedule	`timer`	`$.interface.timer`	How often to poll the Slack API
Channel ID	`channelId`	`string`	Select a value from the drop down menu.

Trigger Authentication#

Slack Bot uses API keys for authentication. When you connect your Slack Bot account, Pipedream securely stores the keys so you can easily authenticate to Slack Bot APIs in both code and no-code steps.

In the settings for your Slack app, visit the OAuth & Permissions section on the left. You'll see a token labeled Bot User OAuth Access Token. Copy and paste that below.

See Slack's docs on Bot User Tokens for more info.

Action Authentication#

Twilio uses API keys for authentication. When you connect your Twilio account, Pipedream securely stores the keys so you can easily authenticate to Twilio APIs in both code and no-code steps.

To connect your Twilio account to Pipedream,

API Key and API Key SID

First, create an API key in Twilio.

There are three types of keys: Main, Standard, and Restricted. You'll need a Main key to interact with certain API endpoints, like /Accounts.
If you don't need to interact with those endpoints, you can use a Standard or Restricted key.

After creating your key, you'll see fields for Sid and Secret. Enter those in the fields below.

Account SID and Auth Token

Visit your Twilio Dashboard. You'll see your Account SID and Auth Token under Account info.
