The API Explorer is for developers to visually interact with our APIs. You can make requests to the Square API to easily test and examine endpoints right in your browser.

The API Explorer supports all publicly available v2 APIs. It includes both Sandbox and Production domains along with your API Key to make requests to either environment.
