Under the Hood: Universal Commerce Protocol (UCP)

Summary

The Universal Commerce Protocol (UCP) is an open-source standard developed by Google to facilitate seamless commerce experiences across various consumer interfaces and payment providers. It aims to standardize the commerce journey by providing a unified integration point that simplifies the complexities of traditional retail infrastructures.
