First you need to find the value of the `data-sitekey` parameter in the page source. Open **DevTools** and locate the element with the `data-sitekey` attribute:

```html theme={null}
<div id="recaptcha-demo"
     class="g-recaptcha"
     data-sitekey="6Le-wvkSAAAAAPBMRTvw0Q4Muexq9bi0DJwx_mJ-"
     data-callback="onSuccess"
     data-action="action">
```

## 1. Create task

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

#### Body Parameters

### Response

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

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

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

## 2. Retrieve the 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": {
      "gRecaptchaResponse": "3AHJ_VuvYIBNBW5yyv0zRYJ75VkOKvhKj9_xGBJKnQimF72rfoq3Iy-DyGHMwLAo6a3"
    }
  }
  ```

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

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

* `errorId = 0` & `status = "ready"` → read the token from `solution.gRecaptchaResponse`
* `errorId = 0` & `status = "processing"` → job in progress, **wait 2 seconds** and retry
* `errorId = 1` → failed, check `errorCode` in [Error Codes](/en/api/error-codes)

<Tip>
  In DevTools, find the `<textarea name="g-recaptcha-response">` element and paste the received token into it, then click the **Check** / submit button.
