Woocommerce API integration

Hi people

Im trying to get the woocommerce using basic authentication. I doesnt work. But it can be done through Oauth1. According to the doucmetnation, it can be done but I dont know what I did wrong. i am using postman for calling the api.
I really need to do it on basic authentication because it is easier to code. Or if you know how to do oauth1 on php, please feel free to answer my query.

Any tips?
