# Retrieving Sessions

> Use the Request API to retrieve session data, allowing you to analyze conversation threads.

The [Request API](/rest/request/post-v1requestquery) allows you to fetch all requests associated with a specific session ID, making it easy to analyze conversation threads.

## Retrieving Session Data

Here's how to fetch all requests for a specific session:

```javascript
const response = await fetch("https://api.helicone.ai/v1/request/query", {
  method: "POST",
  headers: {
    "Content-Type": "application/json",
    Authorization: `Bearer ${HELICONE_API_KEY}`,
  },
  body: JSON.stringify({
    filter: {
      properties: {
        "Helicone-Session-Id": {
          equals: SESSION_ID_TO_REPLAY,
        },
      },
    },
  }),
});
const data = await response.json();
```

The response includes these key fields for each request:

- `request_created_at`: Timestamp of the request
- `request_properties["Helicone-Session-Id"]`: Session identifier
- `signed_body_url`: URL to access the request and response body from S3
- `request_path`: API endpoint path
- `request_properties["Helicone-Session-Path"]`: Session path
- `request_properties["Helicone-Prompt-Id"]`: Unique prompt identifier
- `body`: Deprecated, use `signed_body_url` instead
- `other fields`: See the [Request API reference](/rest/request/post-v1requestquery) for more details
