                                {
                                    "option_type_id": 263,
                                    "sku": null,
                                    "price": 0,
                                    "price_type": "FIXED",

                                {
                                    "option_type_id": 264,
                                    "sku": null,
                                    "price": 200,
                                    "price_type": "FIXED",
                                    "title": "Enterprise",
                                    "sort_order": 2
                                }
                            ]
                        }
                    ]
                }
            ]
        }
    }
}

For adding into cart i query

mutation {
  addDownloadableProductsToCart(
    input: {
      cart_id: "JTjda91utKM3gzQBkOUTtCZB2EHm8qWU"
      cart_items: {
        data: {
          sku: "FME_135_M2"
          quantity: 1
        }
        downloadable_product_links: [
          {
            link_id: 2091
          }
        ]
        customizable_options: [
        { id: 127
          value_string: "273"
         }
          { id: 127
          value_string: "272"
         }
          { id: 259
          value_string: "263"
         }]   
      }
    }
  ) {
    cart {
      items {
        product {
          id
          sku
          name
        }
        quantity
        ... on DownloadableCartItem {
          links {
            title
            price
          }
          samples {
            title
            sample_url
          }
        }
      }
    }
  }
}

But in the cart it only adds the required options not others ( Check boxes )

Answer 1

You should request uid when you get the product. At the time of addProductsToCart mutation you should return uid in the selected_options array
