Need to create a discount code to a specific cutomer using graphql

[Rajith]

  $query = <<<'QUERY'

            mutation discountCodeBasicCreate($basicCodeDiscount: DiscountCodeBasicInput!) {

              discountCodeBasicCreate(basicCodeDiscount: $basicCodeDiscount) {

                codeDiscountNode {

                  codeDiscount {

                    ... on DiscountCodeBasic {

                      title

                      codes(first: 10) {

                        nodes {

                          code

                        }

                      }

                      startsAt

                      endsAt

                      customerSelection {

                        ... on DiscountCustomers {

                          customers

                      }

                      customerGets {

                        value {

                          ... on DiscountPercentage {

                            percentage

                          }

                        }

                        items {

                          ... on AllDiscountItems {

                            allItems

                          }

                        }

                      }

                      appliesOncePerCustomer

                    }

                  }

                }

                userErrors {

                  field

                  code

                  message

                }

              }

            }

          QUERY;

        $variables = [

            "basicCodeDiscount" => [

                "title" => "20% Rajith Sahampathh",

                "code" => "SUMMER20",

                "startsAt" => "2022-06-21T00:00:00Z",

                "endsAt" => "2022-09-21T00:00:00Z",

                "customerSelection" => [

                    "customers" => [

                        81044372851254

                    ],

                ],

                "combinesWith" => [

                    "orderDiscounts" => true

                ],

                "customerGets" => [

                    "value" => [

                        "percentage" => 0.2,

                    ],

                    "items" => [

                        "all" => true,

                    ],

                ],

                "appliesOncePerCustomer" => true,

            ],

        ];

What is the issue of this. When add for all customers works fine.

Hi Rajith,

I was able to get something very similar to work with this mutation - you should be able to adjust it for your purpose:

mutation CreateDiscountCode {
  discountCodeBasicCreate(
    basicCodeDiscount: {
      title: "20% off all products",
      code: "DISCOUNT20",
      startsAt: "2023-10-01T00:00:00Z",
      endsAt: "2023-12-31T23:59:59Z",
      customerSelection: {
        customers: {
          add: ["gid://shopify/Customer/12345678"]
        }
      },
      customerGets: {
        value: {
          percentage: 0.2
        },
        items: {
          all: true
        }
      },
      appliesOncePerCustomer: true
    }
  ) {
    codeDiscountNode {
      codeDiscount {
        ... on DiscountCodeBasic {
          title
          codes(first: 10) {
            nodes {
              code
            }
          }
          startsAt
          endsAt
          customerSelection {
            ... on DiscountCustomers {
              customers {
                id
              }
            }
          }
          customerGets {
            value {
              ... on DiscountPercentage {
                percentage
              }
            }
            items {
              ... on AllDiscountItems {
                allItems
              }
            }
          }
          appliesOncePerCustomer
        }
      }
    }
    userErrors {
      field
      code
      message
    }
  }
}

You just need to replace `gid://shopify/Customer/12345678` with `gid://shopify/Customer/81044372851254` and it should work.

Thanks a lot brother. It worked for me.
