E-Commerce abandoned cart resources represent abandoned carts in an external e-commerce service such as Shopify. The API allows you to create abandoned cart resources. Before you can create any abandoned carts, you must have created a connection resource for the e-commerce service and a customer resource for the customer who abandoned the cart.
The automation start Abandons cart will only trigger if the E-Commerce order source is from a realtime webhook
ecomOrder.source = 1. For more information please read this article.
To create an abandoned cart, use the same API as creating an order, but rather than include an externalid, include an externalcheckoutid and abandoned_date.
To mark an existing abandoned cart as recovered, update the existing cart and include an externalid.
