New Reaction Added (Instant) on Slack

Description:Emit new event when a member has added an emoji reaction to a message

Version:1.1.25

Slack Overview#

The Pipedream Slack app enables you to build event-driven workflows that interact with the Slack API. Once you authorize the Pipedream app's access to your workspace, you can use Pipedream workflows to perform common Slack actions or write your own code against the Slack API.

The Pipedream Slack app is not a typical app. You don't interact with it directly as a bot, and it doesn't add custom functionality to your workspace out of the box. It makes it easier to automate anything you'd typically use the Slack API for, using Pipedream workflows.

Automate posting updates to your team channels
Create a bot to answer common questions
Integrate with your existing tools and services
And much more!

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	`slack`	`app`	This component uses the Slack app.
N/A	`db`	`$.service.db`	This component uses `$.service.db` to maintain state between executions.
Channels	`conversations`	`string[]`	Select a value from the drop down menu.
	`slackApphook`	`$.interface.apphook`
Ignore Bots	`ignoreBot`	`boolean`	Ignore messages from bots
Icon (emoji)	`iconEmoji`	`string[]`	Select a value from the drop down menu.
Include User Data	`includeUserData`	`boolean`	Include user object in the response. Default `false`

Trigger Authentication#

Slack uses OAuth authentication. When you connect your Slack account, Pipedream will open a popup window where you can sign into Slack and grant Pipedream permission to connect to your account. Pipedream securely stores and automatically refreshes the OAuth tokens so you can easily authenticate any Slack API.

Pipedream requests the following authorization scopes when you connect your account:

channels:historychannels:readchannels:writeemoji:readgroups:historygroups:readgroups:writeim:historyim:readim:writelinks:readlinks:writempim:historympim:readmpim:writereactions:readreactions:writereminders:readreminders:writestars:readteam:readusergroups:readusergroups:writeusers:readusers:read.emailusers:writechat:write:botchat:write:userfiles:write:usercommandsusers.profile:writeusers.profile:readsearch:read

About Slack#

Slack is a channel-based messaging platform. With Slack, people can work together more effectively, connect all their software tools and services, and find the information they need to do their best work — all within a secure, enterprise-grade environment.

Action#

Run Node Code on Node

Description:Write custom Node.js code and use any of the 400k+ npm packages available. Refer to the [Pipedream Node docs](https://pipedream.com/docs/code/nodejs) to learn more.

Node Overview#

Develop, run and deploy your Node.js code in Pipedream workflows, using it between no-code steps, with connected accounts, or integrate Data Stores and File Stores

This includes installing NPM packages, within your code without having to manage a package.json file or running npm install.

Below is an example of installing the axios package in a Pipedream Node.js code step. Pipedream imports the axios package, performs the API request, and shares the response with subsequent workflow steps:

Action Code#

import node from "../../node.app.mjs";

export default {
  name: "Run Node Code",
  version: "0.0.2",
  key: "node-run-node-code",
  description: "Write custom Node.js code and use any of the 400k+ npm packages available. Refer to the [Pipedream Node docs](https://pipedream.com/docs/code/nodejs) to learn more.",
  props: {
    node,
  },
  type: "action",
  methods: {},
  async run({
    steps, $,
  }) {
    // Return data to use it in future steps
    return steps.trigger.event;
  },
};
