Update checkout products is a WordPress ability from CartFlows — usable via Easy MCP AI, which connects Claude, ChatGPT, and any AI assistant to your site.
Install Free Plugin →Update checkout products
WriteSet or replace the products assigned to a CartFlows checkout step.
Requires the CartFlows plugin on WordPress 6.9+, since abilities only register when WordPress's Abilities API (wp_register_ability / WP_Ability) is available. Every ability additionally requires the current user to hold the 'cartflows_manage_flows_steps' capability. Flow and step lifecycle abilities (publish, unpublish, clone, trash, restore, update, reorder, clone-step, update-step-title) are further gated by the 'cartflows_abilities_api_edit' site option, while settings, checkout, thank-you, optin, email-report, product-mapping, creation, and template-import abilities are gated by the separate 'cartflows_abilities_api_write' option — both default to enabled but let site admins disable write access independently. WooCommerce must also be active for the analytics, checkout, thank-you, optin, and product-flow-mapping abilities, and for importing flow templates.
What it does
This ability replaces the full list of products loaded into a checkout step's cart. Each product entry sets a WooCommerce product ID, quantity, an optional discount type/value (percent, fixed price, or coupon), and whether it's added to cart. Requires WooCommerce. Use it to configure exactly what a customer buys when they land on this checkout.
