REST api not working - php

Question

I am new to php development. Just for practicing I am creating a rest API following a video tutorial. I have followed each and every step but still unable to get the desired result. Below is the code
Employee Model
class Employee extends \yii\db\ActiveRecord
{
const SCENARIO_CREATE = 'create';
/**
* #inheritdoc
*/
public static function tableName()
{
return 'employee';
}
/**
* #inheritdoc
*/
public function rules()
{
return [
[['emp_name', 'emp_email', 'emp_sal'], 'required'],
[['emp_name', 'emp_email', 'emp_sal'], 'string', 'max' => 100],
];
}
public function scenarios()
{
$scenarios = parent::scenarios();
$scenarios['create'] = ['emp_name','emp_email', 'emp_sal'];
return $scenarios;
}
/**
* #inheritdoc
*/
public function attributeLabels()
{
return [
'id' => 'ID',
'emp_name' => 'Emp Name',
'emp_email' => 'Emp Email',
'emp_sal' => 'Emp Sal',
];
}
}
Above the ID field is auto-increment
Employee Controller
public function actionCreateEmployee()
{
\Yii::$app->response->format= \yii\web\Response::FORMAT_JSON;
$employee = new Employee();
$employee-> scenario = Employee::SCENARIO_CREATE;
$employee->attributes = \Yii::$app->request->post();
if ($employee->validate())
{
return array('status'=> true, 'data' => 'Employee Created Sussessfully');
}
else
{
return array('status'=> false, 'data'=>$employee->getErrors());
}
//return array('status'=> true);
}
Now when I run the API in Postman. I got the following result.
Though I have entered all the required fields data still it gives me false status
Any help would be highly appreciated

You need to select x-www-form-urlencoded
The documentation says that the $_POST-parameter only gets filled on application/x-www-form-urlencoded or multipart/form-data and yii is probably using this.
An associative array of variables passed to the current script via the HTTP POST method when using application/x-www-form-urlencoded or multipart/form-data as the HTTP Content-Type in the request.
from php.net
