# Checkout Enablement {% hint style="info" %} Not following these best practices may result in customers having an impacted experience if something goes wrong in XCE or a downstream dependancy. {% endhint %} Some partners may wish to prevent the user from continuing through the checkout journey until they have selected an option for XCover protection. Because XCE is a third party dependency, we do not want to adversely affect the customer checkout journey. To that end, we strongly recommend that partners integrate our widget using the following practices: * Use `onSet` promise in the set signal layer to wait for a response and control the user experience after. * If `onSet` promise resolves then we can disable the Checkout Button to wait for users to select an insurance option from the widget. * If `onSet` promise catches an error then we shouldn't disable the Checkout Button to avoid affecting the user checkout flow.\ **Note**: Any time the request fails you can expect `onSet` to throw an error so you can catch it and react to it. * If the `onSet` is never called that means there was an issue loading the script. As long as the Checkout Button is enabled by default this should not cause an issue. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
