Why CoCart?
WooCommerce’s Store API can be used headless, but it was designed for the Gutenberg block editor ecosystem. Its session model relies on nonces passed via response headers — suited for anonymous single-session shoppers, but the nonce is tied to WordPress’s nonce lifecycle and less straightforward to persist across sessions or devices.
CoCart is purpose-built for headless from day one: cart sessions identified by a persistent key — no nonces, no cookies — a single unified endpoint set for both product and cart data, and authentication for customers that supports any shop requirement.
