Odoo OpenCart Integration

OpenCart is a lightweight open-source commerce platform. It is simple to run a store on, but it has a thinner API surface than larger platforms, which shapes how an integration is built.

Integrating OpenCart with Odoo moves catalogue, stock and finance into Odoo while OpenCart stays the storefront.

OpenCart does not ship a complete REST API in every version, so the integration commonly uses a connector extension installed on the OpenCart side to expose products, stock and orders.

• Odoo to OpenCart: products, options, prices and stock.
• OpenCart to Odoo: orders, customers and order status.
• Two-way: inventory, usually on a scheduled cycle.

• API extension required. Most OpenCart versions need an extension to expose a usable API, which must be installed and maintained.
• Version fragmentation. OpenCart versions and forks differ, so the integration is tied to a specific version.
• Options versus variants. OpenCart product options need mapping to Odoo variants.
• Limited events. Without webhooks, syncing is scheduled rather than real time.
• Theme customisations. Heavily modified OpenCart installs can change data shapes.

1. Install and configure a connector extension on the OpenCart store.
2. Confirm the OpenCart version and lock the integration to it.
3. Agree the product and option mapping.
4. Run an initial sync and verify a sample.
5. Set a scheduled sync cycle for orders and stock.
6. Confirm the order-to-invoice flow and monitor.
