I get this working using the

DiscountApplicationStrategy.All

Here is my function result output:

{
  "discounts": [
    {
      "targets": [
        {
          "productVariant": {
            "id": "gid://shopify/ProductVariant/40927689801903"
          }
        }
      ],
      "value": {
        "percentage": {
          "value": 15
        }
      },
      "message": "15% off for 3+"
    },
    {
      "targets": [
        {
          "productVariant": {
            "id": "gid://shopify/ProductVariant/40927683149999"
          }
        }
      ],
      "value": {
        "percentage": {
          "value": 10
        }
      },
      "message": "10% off for 2"
    },
    {
      "targets": [
        {
          "productVariant": {
            "id": "gid://shopify/ProductVariant/40927683084463"
          }
        }
      ],
      "value": {
        "percentage": {
          "value": 10
        }
      },
      "message": "10% off for 2"
    },
    {
      "targets": [
        {
          "productVariant": {
            "id": "gid://shopify/ProductVariant/40927689703599"
          }
        }
      ],
      "value": {
        "percentage": {
          "value": 15
        }
      },
      "message": "15% off for 3+"
    }
  ],
  "discountApplicationStrategy": "ALL"
}

And here is the array with the discounts that I am sending to the discount field in the return of the run function,

[
  {
    "targets": [
      {
        "productVariant": {
          "id": "gid://shopify/ProductVariant/40927689801903"
        }
      }
    ],
    "value": {
      "percentage": {
        "value": 15
      }
    },
    "message": "15% off for 3+"
  },
  {
    "targets": [
      {
        "productVariant": {
          "id": "gid://shopify/ProductVariant/40927683149999"
        }
      }
    ],
    "value": {
      "percentage": {
        "value": 10
      }
    },
    "message": "10% off for 2"
  },
  {
    "targets": [
      {
        "productVariant": {
          "id": "gid://shopify/ProductVariant/40927683084463"
        }
      }
    ],
    "value": {
      "percentage": {
        "value": 10
      }
    },
    "message": "10% off for 2"
  },
  {
    "targets": [
      {
        "productVariant": {
          "id": "gid://shopify/ProductVariant/40927689703599"
        }
      }
    ],
    "value": {
      "percentage": {
        "value": 15
      }
    },
    "message": "15% off for 3+"
  }
]

This is for a tiered quantity discount offer.

  1. Group By ProductID and Sum Quantities
  2. Apply discount to variants based on the grouped quantities by product.
