Prepare for the Quickstart

Before you begin, you need a Square account and account credentials. You use the Square Sandbox for the Quickstart exercise.

  1. Create a Square account and an application. For more information, see Create an Account and Application.

  2. Get a Sandbox access token from the Developer Console. For more information, see Make your First API Call.

  3. Install the following:

    • Ruby - Square supports Ruby version 2.7 or later.

    • Square Ruby SDK - To install it, use the gem command:

      gem install square.rb
