# Afterpay Migration

> **Important**
>
> If your app uses an explicit allowlist of Afterpay domains, you *must* add `api.cash.app` and `cash.app` to the allowlist.

## API integration

There are no changes to the APIs, so you don't need to make any changes to your backend systems. While the terminology has changed, the API endpoints are the same.

## Afterpay Messaging

We currently support two messaging products, both of which work with Afterpay.

[On-Site Messaging](../AFTERPAY-MESSAGING/Getting-Started-with-Afterpay-On-Site-Messaging.md) is our current messaging product. Our previous product is messaging from the [JavaScript Library](../AFTERPAY-MESSAGING/JavaScript-Library.md).

**On-Site Messaging**

If you use On-Site Messaging, it will be updated automatically, with advance notice sent via email.

If you use elements of Afterpay Messaging, then see the [Getting Started with Afterpay On-Site Messaging](../AFTERPAY-MESSAGING/Getting-Started-with-Afterpay-On-Site-Messaging.md) page for more information.

**JavaScript Library**

If you use the JavaScript Library for your messaging, it will be updated automatically, with advance notice sent via email.

> **Note**
>
> If you use a specific version of the script, update to version `1.x.js`.
