Every Slack app has access to a bag of tricks—a range of APIs that provide access to read, write, and update many types of data in Slack.
Read on to learn about our core APIs, and discover how to use them to make magic.
The Web API supplies a collection of HTTP methods that underpin the majority of Slack app functionality.
With over 100 methods available to use, it's impossible to explain everything that's possible with the Web API, but we're sure there's one right for your app.
Our Web API usage guide will explain the basic process of interacting with these methods. Once you've figured that out, dive into the list of available methods.
The Events API is a streamlined way to build apps that respond to activities in Slack.
Subscribe to the events you want from a range of possibilities. Build a Slack app that can react to those events usefully.
Tell us where to send the events you carefully select and we'll push them to your app securely. We'll even retry when things don't work out.
Read our Events API usage guide to learn how to subscribe to and handle events.
If you don't wish to expose a public, static HTTP endpoint to communicate with Slack, Socket Mode can help.
Beyond the Web and Events APIs, we have a range of other niche APIs that are suitable for very specific types of apps.
