woocommerce_rest_cannot_view, Sorry, you cannot list resources, 401

I am new to wordpress & woocommerce, actually one wordpress developer developed our website i just need to integrate only woocommerce rest api so as per woocommerce documents i have tried all GET/PUT/POST requests but not got success result, for GET i have got ‘woocommerce_rest_cannot_view’& for PUT/POST got ‘woocommerce_rest_cannot_edit’ request url is https://*******.com/wp-json/wc/v3/products. I have google it many times and checked multiple times after generate API keys and i have also talked with the developer who developed this website and he give me one new request url https://*******.com/wc-api/v3/products on this GET requests are performed well but PUT/POST not working and we got ‘woocommerce_api_missing_product_data’ in the response, i am totally confused why actual request not working and why one different url is working for GET only.
