Introduction

How-tos, tutorials and everything you need to build with Commerce Layer

Need to fetch prices and inventory, manage shopping carts, customer accounts, or checkout orders? This collection of guides and step-by-step tutorials is what you need, featuring how-tos, handy examples, and best practices for the most common scenarios.

How it works

Each guide roughly follows the same schema and is developed across four main sections:

1. Problem A presentation of the issue you are facing.

2. Solution The recommended way to solve the problem. This is where you find the API calls you need to make, along with request/response detailed examples and an image that shows how the involved elements are mapped to the related resource fields.

3. Additional notes A special focus and some highlights of critical aspects around the topic, best practices, suggestions and more in-depth information.

4. More to read Links to the API reference, articles, blog posts, or any other resource that can help you getting more information about the subject.
