  ```

  ```php PHP theme={null}
  <?php
  $payload = [
      "clientKey" => "OMO_API_KEY",
      "task" => [
          "type" => "Tiktok3DSelectObjectPhoneTask",
          "imageBase64" => "BASE64_BODY_HERE",
      ],

### Response

**Success**

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

The server returns `errorId = 0` and a `taskId` on success.

**Failure**

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

The server returns `errorId = 1` with the error in `errorCode`.

## 2. Get the task result

**Endpoint**

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

### Request

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

### Response

**Success**

```json theme={null}
{
  "errorId": 0,
  "status": "ready",
  "solution": {
    "pointA": { "x": 50, "y": 30 },
    "pointB": { "x": 100, "y": 70 }
  }
}
```

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

* `pointA` — coordinates of the first object (x, y).
* `pointB` — coordinates of the second object (x, y).

These two points correspond to the 2 objects that share the same shape.

**Processing**

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

The server returns `errorId = 0` and `status = processing` — the task is being solved, wait **2 seconds** and try again.

**Failure**

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

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