AJAX API

Apps written for Shopify themes call these endpoints; Smootify answers them on the page with the response Shopify would give. ajaxApi: false in SmootifyUserOptions turns them off.

The same cart the page shows.

POST /cart/add.js, POST /cart/add, POST /cart/add.json

Form-encoded or JSON, items[], properties, selling_plan; sections ignored.

POST /cart/update.js, POST /cart/update.json

POST /cart/change.js
