<Info>
The assistant message v1 endpoint is compatible with **AI SDK v4**. If you use AI SDK v5 or later, use the [assistant message v2 endpoint](/api/assistant/create-assistant-message-v2) instead.
</Info>
## Integration with `useChat`
The `useChat` hook from Vercel's AI SDK is the recommended way to integrate the assistant API into your application.
<Steps>
<Step title="Install AI SDK v4">
```bash
npm i ai@^4.1.15
```
</Step>
<Step title="Use the hook">
```tsx
import { useChat } from 'ai/react';
function MyComponent({ domain }) {
const { messages, input, handleInputChange, handleSubmit, isLoading } = useChat({
api: `https://api.mintlify.com/discovery/v1/assistant/${domain}/message`,
headers: {
'Authorization': `Bearer ${process.env.PUBLIC_MINTLIFY_ASSISTANT_KEY}`,
},
body: {
fp: 'anonymous',
retrievalPageSize: 5,
context: [
{
type: 'code',
value: 'const example = "code snippet";',
elementId: 'code-block-1',
},
],
},
streamProtocol: 'data',
sendExtraMessageFields: true,
});
return (
<div>
{messages.map((message) => (
<div key={message.id}>
{message.role === 'user' ? 'User: ' : 'Assistant: '}
{message.content}
</div>
))}
<form onSubmit={handleSubmit}>
<input value={input} onChange={handleInputChange} />
<button type="submit">Send</button>
</form>
</div>
);
}
```
**Required configuration for Mintlify:**
- `streamProtocol: 'data'` - Required for streaming responses.
- `sendExtraMessageFields: true` - Required to send message metadata.
- `body.fp` - Fingerprint identifier (use 'anonymous' or a user identifier).
- `body.retrievalPageSize` - Number of search results to use (recommended: 5).
**Optional configuration:**
- `body.context` - Array of contextual information to provide to the assistant. Each context object contains:
- `type` - Either `'code'` or `'textSelection'`.
- `value` - The code snippet or selected text content.
- `elementId` (optional) - Identifier for the UI element containing the context.
- `body.currentPath` - The path of the page the user is currently viewing. When provided, the assistant uses this context to provide more relevant answers. Maximum length: 200 characters.
</Step>
</Steps>
See [useChat](https://ai-sdk.dev/docs/reference/ai-sdk-ui/use-chat) in the AI SDK documentation for more details.
