Sandbox 101: Getting Started with Terminal API

Build a custom point of sale that connects to Square Terminal, an all-in-one credit card device, from your preferred mobile or web platform. Use Square Terminal to accept Apple Pay, Google Pay, and credit card payments (chip and magstripe). We show you in this tutorial how easy it is to make a simple cURL request in your CLI to connect a Square Terminal device and then make a payment from any internet connected device. Since Terminal API is managed through backend API calls, you can use it with apps built on iOS, Android, Flutter, React Native, Windows, or any web platform. 00:00 - Introduction to Terminal API 00:29 - Terminal API Overview 00:50 - Initiating Checkout via Command Line 01:08 - Payment Method and Terminal Interaction 01:28 - Development Process and API Setup 01:47 - Setting Up Webhooks 02:05 - Webhook Configuration 02:46 - Webhook Event Selection 03:06 - Testing Webhook Events 03:30 - Connecting Terminal Device via API 03:49 - Command Line Device Connection 04:07 - Setting Device Options 04:47 - Device Login and Webhook Confirmation 05:15 - Creating a Checkout 05:39 - Exploring API Options 06:00 - Tipping and Checkout Options 06:37 - Setting Checkout Duration 07:14 - Processing a Payment 07:36 - Summary and Conclusion 08:02 - Closing Remarks and Additional Resources Terminal API: https://developer.squareup.com/docs/terminal-api/overview Square Developer Forums – https://developer.squareup.com/forums Square Developer Community – https://squ.re/slack Square Developer Twitter – https://twitter.com/squaredev Square Developer Blog – https://developer.squareup.com/blog
