| 11 | + |
| 12 | +In order to simplify the flow of adding different types of products to a cart, it is proposed to use a single mutation for all product types. |
| 13 | + |
| 14 | +We implemented the single mutation "AddProductsToCart" from Magento 2.4.1. |
| 15 | + |
| 16 | +The `addProductsToCart` mutation allows you to add any number of products to the cart at the same time. |
| 17 | + |
| 18 | +To add products to a cart, you must provide the cart ID, the SKUs, and the quantities. You can also optionally provide customizable options. |
| 19 | + |
| 20 | +## Syntax |
| 21 | + |
| 22 | +```graphql |
| 23 | +mutation { |
| 24 | + addProductsToCart( |
| 25 | + cartId: String |
| 26 | + cartItems: [CartItemInput] |
| 27 | + ) { |
| 28 | + AddProductsToCartOutput |
| 29 | + } |
| 30 | +} |
| 31 | +``` |
| 32 | + |
| 33 | +## Example usage |
| 34 | + |
| 35 | +These examples show the minimal payload and a payload that includes customizable options. |
| 36 | + |
| 37 | +### Add a product to a cart |

| 255 | + |
| 256 | +- Uid is unique across different options |
