# About the Messages API

The Wix AI Site-Chat Messages API enables you to manage site visitor messages to and from the site's AI Site-Chat.

With this API, you can:
- Create messages between a site visitor and the site's AI Site-Chat.
- Retrieve a site visitor's messages to and from the site's AI Site-Chat.

> **Note:** Wix AI Site-Chat is currently only available in the Wix Editor.


## Before you begin
It's important to note the following points before starting to code:
* Sites using this API must install the [Wix AI Site-Chat](https://www.wix.com/app-market/web-solution/wix-ai-assistant-client) app. Learn more about [adding and setting up Wix AI Site-Chat](https://support.wix.com/en/article/adding-and-setting-up-the-wix-ai-chat-assistant).
* The methods in this API must be called using the [site visitor or site member identity](https://dev.wix.com/docs/rest/articles/getting-started/about-identities.md#site-member) to identify the site visitor that is creating or retrieving the messages. Therefore, [Wix apps](https://dev.wix.com/docs/build-apps.md) can't currently call theses method using REST.

## Use cases
- [Check that a response has been sent to every message from the site visitor](https://dev.wix.com/docs/rest/business-management/ai-site-chat/ai-site-chat/messages/sample-flows.md#check-that-a-response-has-been-sent-to-every-message-from-the-site-visitor)
