Magento 2: How to get Admin Token via Rest API in Postman?

Magento 2: I want to get admin token via Rest API. Early I used:

End point
POST / rest / <store_code> / V1 / integration / admin / token

Headings
Content-Type / json app

Payload
{
“username”: “admin”,
“password”: “123123q”
}

But now this method doesn’t work. Can anyone please help me?
