In these cases, we may be interested in sharing that resource without requiring authentication or authorization. There are APIs that offer read-only information and little or nothing sensitive, such as a weather prediction APIs. Naturally, it all depends on what type of operations can be performed with our API. AND THE AUTHORIZATION?īut that’s not all, since we must now deal with the Authorization, that is, based on the access credentials we can determine whether or not the user can consume a specific resource. Luckily there are many libraries that make this work easier for the developer. Wow!!!, how much work to make sure that nobody discovers our credentials and that they cannot impersonate us in each invocation of the API. It is a string consisting of three parts (header, payload and signature), which are processed by a hash algorithm with a secret key. There are many mechanisms to generate that token, but the most widespread and documented is the JSON Web Token (JWT) (4).

This mechanism is known as Token-based Authentication (Token Bearer). To avoid this we can include that session id in a token along with more information. The best known mechanism is to use cookies to report the session id (Cookie-based authentication), but this involves storing it both at the source and at the destination and having to manage the status. We just have to store a session id on the server, and inform the web application to use it in each request. Should we send the credentials or hash again with each request? COOKIES BASED AUTHENTICATION This hash cannot be altered or decoded by a third party, and only client and server have all the elements to generate it and be able to trust each other.Īs we can see, things go complicated as we move forward … but what about the following requests? The client generates a hash with the user, the password, the desired resource and the values received from the server.

These values are sent by different headers, in response to a first request that is answered with a code 401.

The server where the API runs, randomly generates a series of values. You just have to try several times and determine if you have access or not.įor these reasons, another method arises: Digest Access Authentication. So the same request is valid for any resource.

and secondly, the resource accessed is not checked.

firstly, base64-based coding is easy to break, and once obtained, any client can use the API,.

This mechanism is called Basic Access Authentication (3).īasic Authentication is not very secure for two reasons: If communication with the API endpoint is not done through HTTPS, someone can listen and read the username and password, even if some coding method is used (usually a user base64: password). In the first step, the application must send the API access credentials by using a header (header Authentication) and this is where we should start to be careful. In the following diagram we can see the interaction between a web application (or our browser) and the backend where the API endpoint is published. The solution is, instead of managing the status on the server, returning a token that the client will send in each new request and that the server will be able to interpret.īut let’s go step by step. On the client side, what we have is another software.

In these cases, the session can be maintained with the user’s browser using a cookie, storing the session identifier on the server side.īut when we deal with REST APIs this is not desirable. It is usually obvious, since it is a human who is interacting with the application from a web client. When developing a web application, this aspect is not essential.

That said, there is a particular aspect of the design of REST API (2) that affects security:įrom the developer’s point of view, this affects how to implement the confirmation of the identity of the user, that is, the authentication, since in each request we must guarantee that the client has permission to access our resources. First, let’s set two basic and important concepts: authentication and authorization.Īuthentication methods guarantee that the users who access our resources are who they say they are.Īuthorization methods ensure that the authenticated user who accesses a certain resource is authorized for that resource.
