Events are useful for real-time integrations, but they can also be used to investigate the history of a single resource, such as a user or a listing, with the Sharetribe CLI. In this article, we will learn how to use the options in the CLI, as well as a tool called jq, to find the details we want to investigate. ![A marketplace landing page section showing four images of bicycles with details under each image.

When checking out a cart, we need to add a few more actions in between the steps of the default flow under the hood. In this blog series, we are diving into the ins and outs of building a multi-vendor shopping cart with single-vendor checkout using the Sharetribe Developer Platform. ![Two paper bags of groceries on a wooden floor.

Therefore both the checkout page and the order page show only the main listing’s information, even if you are checking out a cart full of items. We want to modify this behavior so that cart listing information is displayed instead of the transaction’s default listing.

In a cart transaction flow, we still want to handle the payment in a single transaction with a single set of line items, but we want to handle stock for each listing separately. In this blog series, we are diving into the ins and outs of building a multi-vendor shopping cart with single-vendor checkout using the Sharetribe Developer Platform. ![A farmer's market table full of vegetables and their price signs, with cherry tomato baskets and their price sign in the forefront.](https://images.prismic.io/sharetribe/c11f0fe7-abdb-48f7-9f56-2cd6591f8113_anne-preble-SAPvKo12dQE-unsplash.jpg?auto=compress%2Cformat&fit=max&w=3840) Developer Blog [Calculating shopping cart price](/developer-blog/calculating-shopping-cart-price/) In a default Sharetribe marketplace, a transaction price is calculated based on a single listing.
