To send a message to a Slack channel, you need to make an HTTP POST request to the endpoint with your Slack token in the authorization header.

Once you've installed the app, Slack will give you a bot user token: Once you've added the above scopes, click 'Install App' to install this new Slack app to your workspace. First, make sure you add the following scopes to your bot user: You'll have to add scopes (permissions) to your bot user, and then install your app. Next, go through the steps to create a bot user. Make sure you set 'Development Slack Workspace' to the Slack Workspace you want to use. In order to get a bot user token, you first need to create a new Slack app. Bot user tokens let you post messages as a bot user, with a custom name and avatar, as opposed to as an existing user. But, for the purposes of this article, I'll be using bot user tokens. For example, an OAuth token lets you post messages on behalf of a user. There are several types of Slack token, each with its own permissions. In order to make an API request to Slack, you need a Slack token. However, both and slack are fairly thin wrappers around the Slack API, so, for the purposes of this article, we'll just use axios. I've also used node-slack in the past, but that module is fairly out of date. There are two npm modules that I recommend for working with the Slack API: the official module and the slack module written primarily by Brian LeRoux of WTFJS fame. In this article, I'll explain the basics of how to send a Slack message from Node.js. Slack is the de facto communication platform for many companies, so there's a lot of demand for getting data from Node.js apps to Slack in realtime. Integrating with the Slack API is becoming an increasingly common task. This blog post was first published in The Code Barbarian Blog.
