This tutorial covers how to use ROM APIs with your shopping cart and checkout flow, to see your customers orders through successful completion. The guide covers the following processes:

  • how to check for available inventory

  • how to validate postal addresses

  • how to obtain an estimated delivery dates for all of the lines in an order

  • how to get a tax quote for an order

  • how to validate payments and obtain authorization

  • how to submit an order to ROM

To use the ROM API, you’ll need to obtain the following information from Radial:

  • Your Radial-assigned store identifier

  • Your ROM API key

  • The base URL for the HTTPs endpoints

The sections linked below describe the suggested integration touch points for activities in your cart and checkout flow. Your application can interact with ROM by sending HTTPS POST requests to ROM endpoints.

Before working with the use cases, please review the Radial Data Conventions used by the ROM API platform.
