What type of authentication is REST API?

I am working on a REST API which is being used by some clients.

The API is being consumed using PHP and curl.

The clients are not registered on the server. We don't have any password for them. They are not being connected via network either. The only thing they can do is to send their request to our server via post.

How can we authenticate them in REST API? ? It is not. By making a POST call to the endpoint. But there is no need for client-side authentication.

How to use basic authentication in REST API Postman?

As in rest API is not supported for basic authentication we need to use POSTMAN.

But we couldn't find the best way to use in Postman. So for that, I searched a lot.

I found lots of way to use in REST API. I know to do the HTTP requests with REST Api is with below code : function requestPost(). The above way looks clean. But problem is, It works only when username and password both available. If username is not available and password is also not available, It will return error. XMLHttpRequest cannot load No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'null' is therefore not allowed access. The response had HTTP status code 401.

How can I use simple REST API in postman without these parameters

Thanks in Advance. It seems like you want to use "Authorization": Bearer.open('POST', url); // We send the header along with the data. // You can customize it according to your needs. Xhr.setRequestHeader("Content-Type", "application/x-www-form-urlencoded"); // Send the data

Is Basic Auth for API secure?

When using REST APIs, do we still need to be "thinking like a user" by providing authentication?

How does Basic Authentication play into this in terms of creating security or does it just increase exposure? You're right to assume that if you don't have any "user" authentication, no users will be able to make REST requests. I've built lots of REST APIs in the past and the first thing I tend to do is make sure there is no single point of failure that allows anyone access to my api without authorization.

Basic authentication (in the context of REST) usually provides a simple, safe login mechanism that isn't directly tied to the resource being accessed. When implemented correctly it doesn't change how resource are accessed except as an additional step, when it adds an extra layer of security.

If your API were compromised then any credentials passed would still allow access. So the only advantage you'd gain from basic authentication is to protect against some simple attack scenarios.

For example, imagine the following.
