# AntiAkamaiSensorRelayTask

Compute Akamai `sensor_data` only; your own client session sends it. Use this when the cookie has to come from the session that posted the sensor, such as queue-it entry.

## Task type

`AntiAkamaiSensorRelayTask`

## Sync or poll

Async — poll `/getTaskResult`

## Parameters

| Field | Type | Required | Notes |
|---|---|---|---|
| `type` | string | yes | `AntiAkamaiSensorRelayTask` |
| `sessionId` | string | yes | Generated by you; send the same value in every round |
| `cookies` | object | yes | First round must include `_abck` and `bm_sz`; later rounds send the full cookie jar after your POST |
| `websiteURL` | string | yes | Page URL; first round only |
| `sensorUrl` | string | yes | Sensor script URL; first round only |
| `js` | string | yes | Sensor script body; first round only |
| `pageHtml` | string | no | Page HTML; first round only |
| `userAgent` | string | no | Your client's User-Agent |
| `proxy` | string | no | Optional, first round only; later rounds do not send it |
| `nPosts` | int | no | Sensor posts to generate, 1–7, default 4 |

## Minimal request

```json
{
  "clientKey": "YOUR_API_KEY",
  "task": {
    "type": "AntiAkamaiSensorRelayTask",
    "sessionId": "YOUR_SESSION_ID",
    "websiteURL": "https://TARGET/path",
    "sensorUrl": "https://TARGET/SENSOR",
    "js": "...",
    "cookies": {
      "_abck": "...",
      "bm_sz": "..."
    }
  }
}
```

## Success solution

```json
{
  "sessionId": "YOUR_SESSION_ID",
  "done": false,
  "sensorBody": "...",
  "sensorUrl": "https://TARGET/SENSOR",
  "sensorHeaders": {},
  "contentType": "text/plain;charset=UTF-8"
}
```

## Typical failures

`ERROR_CAPTCHA_UNSOLVABLE`, `ERROR_BAD_REQUEST`, `ERROR_TASK_NOT_SUPPORTED`

## Notes

Each round returns `sensorBody`, `sensorUrl` and `sensorHeaders`. POST `sensorBody` to `sensorUrl` with those headers from your own session, then create the next task with the same `sessionId` and the resulting cookies. When `done` is `true` the session is over and `cookies` holds the final jar.
