The add-to-cart-button block is designed to add products to the Minicart (minicart.v2).

The Add to Cart button is only compatible with stores using Minicart v2. For these stores, it will function correctly on the Shelf component and the Product Details page. If you are using Minicart v1, you should configure the Buy Button block on the Product Details page and the Product Summary Buy button on the Shelf component instead.

1. Import the vtex.add-to-cart-button app to your theme dependencies in the manifest.json file, as follows:

2. Add the add-to-cart-button to another theme block using the product context, such as the product-summary.shelf. In the example below, the add-to-cart-button is added to the flex-layout.row block from the store.product template, which uses the product context:
