### Response

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

  ```

  ```json Failure theme={null}
  {
    "errorId": 1,
    "errorCode": "",
    "errorDescription": ""
  }
  ```
</CodeGroup>

* `errorId = 0` with `taskId` → success
* `errorId = 1` with `errorCode` → failure (see [Error Codes](/en/api/error-codes))

## 2. Get task result

### Request

```http theme={null}
POST https://api.omocaptcha.com/v2/getTaskResult
Content-Type: application/json
```

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

### Response

<CodeGroup>
  ```json Success theme={null}
  {
    "errorId": 0,
    "status": "ready",
    "solution": {
      "index": 1
    }
  }
  ```

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

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

* `errorId = 0` with `status = "ready"` → read the answer from `solution.index`.
* `errorId = 0` with `status = "processing"` → job is still running, wait **2 seconds** and retry.
* `errorId = 1` → failure (see [Error Codes](/en/api/error-codes)).

<Warning>
  The server returns the **position of the correct image** in the sequence. When clicking the right-arrow button on the page, you must **subtract 1** because the captcha image occupies the first position.

  Example: server returns `index = 5` → click the right arrow **4 times**.
</Warning>
