+
+# selectFreeGiftForCart mutation
+
+<Fragment src="/includes/scp-mutation.md" />
+
+The `selectFreeGiftForCart` mutation defines the product that a shopper has selected as a free gift. This mutation is applicable only when a Free Gift cart price rule has been applied to the cart and the rule requires the shopper to choose a gift SKU before placing the order.
+
+Some Free Gift rules add a gift to the cart automatically. Other rules offer multiple SKUs, or a product with configurable or bundle options, and require the shopper to make a selection. Use the following [`Cart`](../queries/cart.md) fields to determine whether a selection is needed and which products are eligible:
+
+*  `has_available_free_gifts` is `true` when at least one applied Free Gift rule is still waiting for the shopper to select a SKU.
+*  `available_free_gifts` lists each rule that requires a selection, along with its `rule_id`, `gift_qty`, `available_skus`, and the corresponding `products`.
+
+After the shopper selects a gift, the mutation adds the product to the cart as a free-gift line item. Line items added by a Free Gift rule return `true` for the `is_free_gift` field on the [`CartItemInterface`](../interfaces/index.md). After the order is placed, the corresponding order item returns the rule label in the `free_gift_label` field on the `OrderItemInterface`.
+
+## Syntax
+
+`mutation: {selectFreeGiftForCart(input: SelectFreeGiftForCartInput!): SelectFreeGiftForCartOutput}`
+
+\<!-- ## Reference
+
+The `selectFreeGiftForCart` reference provides detailed information about the types and fields defined in this mutation.

+
+## Example usage
+
+The following examples show how to determine which Free Gift rules require a selection and how to select a gift SKU for a rule.
+
+### Determine which free gifts require a selection
+
+The following query returns the Free Gift rules that are applied to the cart but still need the shopper to choose a gift SKU.
+
+**Request:**
+
+```graphql
+{
+  cart(cart_id: "8k0Q4MpH2IGahWrTRtqM61YV2MtLPApz") {
+    has_available_free_gifts
+    available_free_gifts {
+      rule_id
+      rule_label
+      gift_qty
+      available_skus
+      products {
+        sku
+        name
+      }
+    }
+  }
+}
+```
+
+**Response:**
+
+```json
+{
+  "data": {
+    "cart": {
+      "has_available_free_gifts": true,
+      "available_free_gifts": [
+        {
+          "rule_id": 5,
+          "rule_label": "Free gift with orders over $50",
+          "gift_qty": 1,
+          "available_skus": [

+          ]
+        }
+      ]
+    }
+  }
+}
