The API2Cart API gives developers a single integration to dozens of shopping cart and marketplace platforms. It reads and writes products, categories, orders, and customers across connected stores through one unified request format, and reports which platforms and webhooks each account supports. A store is linked once with a store key, after which the same calls work regardless of the underlying cart.
Jentic publishes the only available OpenAPI specification for API2Cart, keeping it validated and agent-ready. API2Cart is a unified shopping-cart integration layer: a single API that connects to dozens of ecommerce platforms - Shopify, Magento, WooCommerce, BigCommerce, OpenCart, and others. Use it to add or update products, manage attributes and attribute sets, and read connected-store metadata across many storefronts without writing a separate integration per platform. The 146-endpoint surface covers the core ecommerce object model in a normalised shape.
Step 1: Jentic One Host machine
# On the machine that will host your Jentic One instance:
curl -fsSL "https://jentic.com/install.sh?src=apis&api=%2Fapis%2Fapi2cart.com" | shStep 2: Agent machine
# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL "https://jentic.com/install.sh?src=apis&api=%2Fapis%2Fapi2cart.com" | sh
jentic register # connects your agent to your Jentic One instanceJentic One is in public beta. The setup above keeps your agent separate from the instance, which is what you want before using real credentials: an agent running as the same OS user as Jentic One can read its stored keys directly. Just evaluating? A single local install is fine to start. See the secure deployment guide for the tiers.
