At this time, OGO only natively supports Shopify via our OGO Shopify App. We do have plans to support WooCommerce once the Shopify app has launched to the public (via the Shopify App Store).
There are options for manually integration WooCommerce with OGO. If you run an existing, high volume store, chat with our team and we can discuss options. We also have an API for companies/teams that have the development capability to develop their own integrations with OGO.
