Prerequisites

Complete these prerequisites before you begin the quick start.

Become familiar with:

cURL, which is a command-line tool the quick start uses as the client application that makes HTTP requests to Salesforce.
JavaScript Object Notation (JSON), which is the data format returned in this quick start.
OAuth 2.0, which is the framework Salesforce uses for authentication. The quick start provides the steps, but it would be helpful to familiarize yourself with OAuth terms and concepts.
