+
+The `applyRewardPointsToCart` mutation applies reward points to the customer's cart. You cannot specify a quantity of reward points. If the reward points balance is less than the cart total, Magento applies the entire reward points balance. Otherwise, Magento applies as many reward points needed to bring the total to 0. Fractional reward points are discarded.
+
+Use the [`removeRewardPointsFromCart` mutation]({{page.baseurl}}/graphql/mutations/remove-reward-points.html) to undo the results of the `applyRewardPointsToCart` mutation.
+
+## Syntax
+
+`mutation: applyRewardPointsToCart(cartId: ID!): ApplyRewardPointsToCartOutput`
+
+## Example usage
+
+The following example applies $5 to the cart. In this example, the exchange rate is defined as 25 reward points equals $5.
+
+**Request:**
+
+```graphql
+mutation {
+  applyRewardPointsToCart(cartId: "8k0Q4MpH2IGahWrTRtqM61YV2MtLPApz")
