Block Client APIs

This folder contains documentation for API interfaces for Blocks. In most cases, these docs describe APIs and interfaces that are internal only, and thus are provided to assist with developing the blocks in this repository. Documentation will tend to focus on high level overviews.

Document	Description
Checkout API interface	This doc goes into some detail about some of the API specifics for the checkout block architecture.
