What is OAuth 2.0 and how does it work in Slack?

OAuth 2.0 is an authorization framework that allows third-party applications to access user data without sharing passwords. In Slack, it enables apps to authenticate users and access their Slack data securely.

Can you explain the steps to implement OAuth 2.0 in a Slack app?

Sure! First, you need to create a Slack app in the Slack API portal. Then, configure the OAuth settings, including redirect URLs and scopes. After that, implement the authorization code flow in your app to handle user authentication.

What are the common scopes used in Slack OAuth?

Common scopes include channels:read, chat:write, and users:read. These define what data your app can access.

How do I handle token expiration in my Slack app?

You should implement a refresh token mechanism to obtain a new access token when the current one expires. This ensures uninterrupted access to Slack APIs.
