# SliderAllWebTask

> Generic web drag-and-drop (slider) captcha solver — returns the target coordinates where the puzzle piece must be dropped.

Drag-and-drop is a very common captcha style on the web. `SliderAllWebTask` is a generic solver for puzzle-piece captchas: you send the background image (with the puzzle hole) and the display size, and the API returns the target coordinates where the piece must be dropped.

## 1. Create a task

**Request**

```http theme={null}
POST https://api.omocaptcha.com/v2/createTask
```

| Parameter          | Type     | Required | Description                                            |
| ------------------ | -------- | :------: | ------------------------------------------------------ |
| `clientKey`        | `String` |     ✅    | Your client account key                                |
| `task.type`        | `String` |     ✅    | Captcha service class name: `SliderAllWebTask`         |
| `task.imageBase64` | `String` |     ✅    | Base64-encoded background image (with the puzzle hole) |
| `task.widthView`   | `Number` |     ✅    | Image display width on the web page (px)               |
| `task.heightView`  | `Number` |     ❌    | Image display height on the web page (px)              |

<Warning>
  `widthView` / `heightView` must match the **actual rendered size** in the browser, not the original image size. Returned coordinates use this coordinate system.
</Warning>

  ```bash cURL theme={null}
  curl -X POST https://api.omocaptcha.com/v2/createTask \
    -H "Content-Type: application/json" \
    -d '{
      "clientKey": "OMO_API_KEY",
      "task": {
        "type": "SliderAllWebTask",
        "imageBase64": "BASE64_BODY_HERE",
        "widthView": 300,
        "heightView": 150
      }
    }'
  ```

  ```javascript Node.js theme={null}
  const res = await fetch("https://api.omocaptcha.com/v2/createTask", {
    method: "POST",
    headers: { "Content-Type": "application/json" },
    body: JSON.stringify({
      clientKey: "OMO_API_KEY",
      task: {
        type: "SliderAllWebTask",
        imageBase64: "BASE64_BODY_HERE",
        widthView: 300,
        heightView: 150,
      },
    }),
  });
  const data = await res.json();
  console.log(data);
  ```

  ```python Python theme={null}
  import requests

  res = requests.post(
      "https://api.omocaptcha.com/v2/createTask",
      json={
          "clientKey": "OMO_API_KEY",
          "task": {
              "type": "SliderAllWebTask",
              "imageBase64": "BASE64_BODY_HERE",
              "widthView": 300,
              "heightView": 150,
          },
      },
  )
  print(res.json())
  ```

  ```php PHP theme={null}
  <?php
  $payload = [
      'clientKey' => 'OMO_API_KEY',
      'task' => [
          'type' => 'SliderAllWebTask',
          'imageBase64' => 'BASE64_BODY_HERE',
          'widthView' => 300,
          'heightView' => 150,
      ],
  ];

  $ch = curl_init('https://api.omocaptcha.com/v2/createTask');
  curl_setopt($ch, CURLOPT_POST, true);
  curl_setopt($ch, CURLOPT_HTTPHEADER, ['Content-Type: application/json']);
  curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($payload));
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
  echo curl_exec($ch);
  ```
</CodeGroup>

**Response**

Success:

```json theme={null}
{
  "errorId": 0,
  "taskId": "49f9f60a-c809-4af0-93c0-0409b72e67e0"
}
```

The server returns `errorId = 0` and a `taskId` when the task is created.

Failure:

```json theme={null}
{
  "errorId": 1,
  "errorCode": "",
  "errorDescription": ""
}
```

The server returns `errorId = 1` with an `errorCode`.

## 2. Get the result

**Request**

```http theme={null}
POST https://api.omocaptcha.com/v2/getTaskResult
```

```json theme={null}
{
  "clientKey": "OMO_API_KEY",
  "taskId": "49f9f60a-c809-4af0-93c0-0409b72e67e0"
}
```

**Response**

Success:

```json theme={null}
{
  "errorId": 0,
  "errorCode": "",
  "errorDescription": "",
  "status": "ready",
  "solution": {
    "rects": [
      { "x": 237, "y": 70, "w": 53, "h": 47 }
    ]
  }
}
```

The server returns `errorId = 0` and `status = ready`. Read the answer from `solution.rects`:

| Field | Type     | Description                                                 |
| ----- | -------- | ----------------------------------------------------------- |
| `x`   | `Number` | X coordinate (px) of the top-left corner of the drop target |
| `y`   | `Number` | Y coordinate (px) of the top-left corner of the drop target |
| `w`   | `Number` | Width of the target area (px)                               |
| `h`   | `Number` | Height of the target area (px)                              |

<Tip>
  Coordinates are expressed in the `widthView` × `heightView` system you sent. If the page renders the image at a different size, scale accordingly before simulating the drag.
</Tip>

Processing:

```json theme={null}
{
  "status": "processing",
  "errorId": 0,
  "errorCode": "",
  "errorDescription": ""
}
```

The server returns `status = processing` — poll again in \~2 seconds.

Failure:

```json theme={null}
{
  "errorId": 1,
  "errorCode": "ERROR_JOB_STATUS",
  "errorDescription": "Job failed",
  "status": "fail",
  "solution": {}
}
```

The server returns `errorId = 1` when solving fails.
