Hi,

For authenticating Odoo From Postman, see this video showing the same: https://www.youtube.com/watch?v=wGvuRbCyytk

Thanks

It's difficult to simulate odoo authentication using postman due to odoo protect all the post request using  Cross-Site Request Forgery (CSRF). you don't have csrf token while making post request so it rejects by odoo.

so first you have to make get a request to get csrf token(a token is embedded inside Html form ) and send it while you make a post request. (I don't know how to get it using postman). 

an alternative is after login through web browser copy the session_id and stores it postman cookie so all the next jsonrpc/AJAX/xhr request validate by the server and it works (I know it's not your requirement ;)

all the auth_* modules are not dependant on each other. it's named as auth_* because it's related to user authentication.

BTW why don't you use xml-rpc instead of a postman. it's very easy to authenticate and you can perform any operation using it. 

Hi everybody. Thanks to Obay for your help, this is my javascript auth from postman. I hope to help you.

var data = JSON.stringify({
"jsonrpc": "2.0",
"params": {
"db": "your_data_base_name",
"login": "your_user_name",
"password": "your_password"
}
});

var xhr = new XMLHttpRequest();
xhr.withCredentials = true;

xhr.addEventListener("readystatechange", function() {
if(this.readyState === 4) {
console.log(this.responseText);
}
});

xhr.open("POST", "http://localhost:8069/web/session/authenticate");
xhr.setRequestHeader("Content-Type", "application/json");

xhr.send(data);
