Erase in odoo doesn'T really support the authentication you want. This code just isn't there. The ode has its own authentication option. When you set "user" it turns on. It consists in the fact that you must first receive a cookie. And then in the postman already pass these cookies in the cookie header. I am sending examples of authentication and subsequent requests from my mobile app. I think it will be clear to you and you will transfer it to the postman. next how use this cookie So you can'T get the data in one request. First you need to get a cookie(token). And then make a request with this cookie. Also note that cookies also come in the set-cookie header By the way, there is another alternative option to create an API KEY in the user's settings and use it
