how can get orders in magento 1 using rest api through postman

i have consumer key and secret and access token generated through

1. https://mydomain/oauth/initiate
2. oauth/initiate
3. /oauth/token

I’m trying to get orders using https://mydomain/api/rest/orders and getting “Access denied” in response. How can I solve it? Please provide Magento 1 resources and ideas on how to resolve this issue.

I’m trying to get products using https://mydomain/api/rest/products. I’m getting a successful response, but there’s no need to pass a token in this URL. Even if I paste it in the browser, I still get a successful response, i.e., {“12”: [], “13”: [], “14”: []}.

Please help me; I don’t have any idea how to grant permissions from the admin panel.
