woocommerce_rest_authentication_error

Hi Guys,
I always receive 401 from woocommerce rest API. I don’t understand the cause.

Wordpress 4.7.4
WooCommerce 3.0.6

1) I generated KEYS from administration panel

2) I use Postman in order to call the WordPress API
– I set OAuth1.0, is it correct?
– I use /wp-json/wc/v2 endpoint, is it correct?
– Postman generate URL:

https://{{HOST}}:{{PORT}}/{{CONTEXT}}/wp-json/wc/v2/products/categories?oauth_consumer_key=ck_fab77b44e3a59e09c1218df3999f0b2b837e8626&oauth_signature_method=HMAC-SHA256&oauth_timestamp=1494856028&oauth_nonce=2sWeUJ&oauth_version=1.0&oauth_signature=ykmBiX5IyHtmGClYNHziXvk0jPxB6SyGkCy3LulDpSc=

3) I always receive this error (in italian language):

{
  "code": "woocommerce_rest_authentication_error",
  "message": "Firma non valida - la firma fornita non corrisponde.",
  "data": {
    "status": 401
  }
}

Could you please help me?

Thanks
Luca
