With Wix Inbox v2, site contributors
can communicate with the site's visitors, contacts, and members
through Wix Chat, SMS, a Facebook business page, or other channels.
Visitor activities on the site and 3rd-party services
can also be displayed in Inbox conversations.

The Inbox APIs expose functionality for working with a site's inbox.
With the Inbox APIs, you can:

- [Send messages](https://dev.wix.com/docs/velo/apis/wix-inbox-v2/messages/send-message.md)
  on behalf of the business or a visitor.
- [Retrieve conversations](https://dev.wix.com/docs/velo/apis/wix-inbox-v2/conversations/get-or-create-conversation.md)
  between a visitor and the business.

<!-- - Handle webhooks when messages are sent to [a visitor](https://dev.wix.com/docs/api-reference/crm/communication/inbox/messages/message-sent-to-participant.md) or [the business](https://dev.wix.com/docs/api-reference/crm/communication/inbox/messages/message-sent-to-business.md), when a [message button is clicked](https://dev.wix.com/docs/api-reference/crm/communication/inbox/messages/button-interacted.md), or when [conversations are merged](https://dev.wix.com/docs/api-reference/crm/communication/inbox/conversations/conversations-merged.md). -->
