+## Additional Notes for int-based Enums
+
+If you want to use the generated input structs that use int-based enums to query your GraphQL server, you need an additional step to convert the int-based enum value into a JSON string representation. Otherwise, most client libraries will send an integer value, which the server will not understand, since it is expecting the string representation (e.g. `ONE` in the above example).
+
+Therefore, we must implement `MarshalJSON` and `UnmarshalJSON` on the typed enum type to convert between both. This is only possible with typed bindings.
+
+```go
+func (t EnumTyped) String() string {
+	switch t {
+	case EnumTypedOne:
+		return "ONE"
+	case EnumTypedTwo:
+		return "TWO"
+	default:
+		return "UNKNOWN"
+	}
+}
+
+func (t EnumTyped) MarshalJSON() ([]byte, error) {
+	return []byte(fmt.Sprintf(`"%s"`, t.String())), nil
+}
+
+func (t *EnumTyped) UnmarshalJSON(b []byte) (err error) {
+	var s string
+
+	if err = json.Unmarshal(b, &s); err != nil {
+		return err
+	}
+
+	switch s {
+	case "ONE":
+		*t = EnumTypedOne
+	case "TWO":
+		*t = EnumTypedTwo
+	default:
+		return fmt.Errorf("unexpected enum value %q", s)
+	}
+
+	return nil
+}
+```
