General Development Concepts

The following topics review some of the basic concepts you should understand when developing applications on the Square platform:

  • TLS and HTTPS - Guidance for enabling HTTPS to call Square APIs over a secured connection.

  • Using the REST API - Information about sending requests to Square APIs and handling responses.

  • Handling Errors - Guidance about error handling and descriptions of the components of an Error object.

  • Best Practices for Collecting Information - Requirements and general guidelines for collecting and managing customer information. If you collect personal information from customers, it's critical that you handle that information responsibly.

  • Language Preferences for Applications - People communicate with software through natural languages, such as English, French, and Spanish. Because each person has a different preferred language, developers must track and accommodate language preferences of customers. This topic explains how applications that integrate the Square API might accommodate these language preferences in communications.
