How to Dynamically Query Shopify Product Tags Stored in Metafields Using GraphQL?

[kristi01]

Hi everyone,

I'm currently working on Shopify function where I need to dynamically replace a static tag name in a GraphQL query with values stored in metafields. For example, in the code below, I'm checking the product tag statically ("winter-sale") using the hasAnyTag function. However, I want to check this tag dynamically using a metafield value instead.

I am using the Remix template to create a discount function and querying the above code in run.graphql.

query RunInput {
  cart {
    lines {
      quantity
      merchandise {
        __typename
        ...on ProductVariant {
            id
            product {
              id,
              tags,
              hasAnyTag(tags: ["winter-sale"]),
            }
        }
      }
    }
  }
  discountNode {
    metafield(namespace: "$app:shopify-discount-new", key: "shopify-configuration-new") {
      value
    }
  }
}

Here is the code for creating a discount and storing values in a metafield.

const response = await admin.graphql(
      `#graphql
          mutation CreateCodeDiscount($discount: DiscountCodeAppInput!) {
            discountCreate: discountCodeAppCreate(codeAppDiscount: $discount) {
              codeAppDiscount{
                discountId
              }
              userErrors {
                code
                message
                field
              }
            }
          }`,
      {
        variables: {
          discount: {
            ...baseCodeDiscount,
            metafields: [
              {
                namespace: "$app:shopify-discount-new",
                key: "shopify-configuration-new",
                type: "json",
                value: JSON.stringify({
                  quantity: configuration.quantity,
                  percentage: configuration.percentage,
                  tag: configuration.tag
                }),
              },
            ],
          },
        },
      },
    );

Could someone help me figure out how to replace the static tag ("winter-sale") with a value retrieved from a metafield?
