OAuth 2.0 Crash Course
The OAuth 2.0 Authorization Code Grant Type is the most common way to authenticate with the other apps and services your customers use. In this video, we cover what OAuth 2.0 is and set up a couple of OAuth 2.0 apps from scratch to show you how to add OAuth 2.0 authentication to your integrations.
