Add email address for discount

[availableuser]

I cannot find documentation that provides an example or work out how to add a customer to a discount code allow list.

Known:

• discount code configured for specific customers
• email address

Goal:

• Get or create customer with the email address
• Add customer to the discount code eligible customer list.

Thank you

Hi there 👋

Have you tried the discountCodeBasicUpdate mutation? 

//Mutaion
mutation discountCodeBasicUpdate($id: ID!, $basicCodeDiscount: DiscountCodeBasicInput!) {
  discountCodeBasicUpdate(id: $id, basicCodeDiscount: $basicCodeDiscount) {
    codeDiscountNode {
      codeDiscount {
        ... on DiscountCodeBasic {
          title
          codes(first: 10) {
            nodes {
              code
            }
          }
          startsAt
          endsAt
          customerSelection {
            ... on DiscountCustomerAll {
              allCustomers
            }
          }
          customerGets {
            value {
              ... on DiscountPercentage {
                percentage
              }
            }
            items {
              ... on AllDiscountItems {
                allItems
              }
            }
          }
          appliesOncePerCustomer
        }
      }
    }
    userErrors {
      field
      code
      message
    }
  }
}
