Problem with Woocommerce REST API Authentication

I am using the postman for the check the REST API Call in WooCommerce.
When I call the Woocommerce Defaults API. It displays the error like.

{
"code": "woocommerce_rest_cannot_create",
"message": "Sorry, you are not allowed to create resources.",
"data": {
    "status": 401
   }
}

The above error displays when the Basic Authentication and POST method of Create Customers API.

And when I am Trying to Call the Display products API with the cURL

http://example.com/wp-json/wc/v2/products

Using the GET Methods from postman it will display the following error.

{
"code": "woocommerce_rest_cannot_view",
"message": "Sorry, you cannot list resources.",
"data": {
    "status": 401
   }
}

It would be great if anyone saving me from this headache.
Thanks..

I got the solution for it. Use the Basic Authentication from the Postman.

Thanks
