# Using Virtual Agent API

Virtual Agent API enables ServiceNow developers, advanced users, and admins to use Virtual Agent with an enterprise or any other third-party chat interface that supports conversational interfaces. You can also use Virtual Agent as a secondary bot in an environment with multiple, specialized bots managed by a primary bot.

The following sections detail how to use Virtual Agent API to complete various tasks, such as closing an idle bot, enabling ServiceNow Otto experience, and various controls for the bot output response.

-   **[Enable synthesized response in Virtual Agent API](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/conversational-interfaces/virtual-agent/va-api-enable-synthesized-response.md)**  
You can now enable synthesized response in the conversations with the primary bot.
-   **[Configure interaction record to store clientSessionId in Virtual Agent API](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/conversational-interfaces/virtual-agent/va-api-interaction-record-third-party-chat.md)**  
You can configure to store **clientSessionId** to support third-party chat applications.
-   **[Configure to support chat history in Virtual Agent API](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/conversational-interfaces/virtual-agent/va-api-support-chat-history.md)**  
You can now support your live agents to see chat history in their conversations with the primary bot.
-   **[Enable ServiceNow Otto experience in Virtual Agent API](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/conversational-interfaces/virtual-agent/enable-now-assist-in-virtual-agent-experience-in-virtual-agent-api.md)**

-   **[Configure multiple provider applications](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/conversational-interfaces/virtual-agent/configure-multiple-provider-applications.md)**  
You can configure multiple provider applications to support AI agents where there are multiple primary bots using Virtual Agent API and you need to distinguish between them.
