How does REST API authentication work?

Authentication is stating that you are who are you are and Authorization is asking if you have access to a certain resource. When working with REST APIs you must remember to consider security from the start. RESTful API often use GET (read), POST (create), PUT (replace/update) and DELETE (to delete a record).

How do I use basic authentication in REST API?

the most simple way to deal with authentication is to use http basic authentication. we use a special http header where we add 'username:password' encoded in base64. note that even though your credentials are encoded, they are not encrypted!

What is OAuth authentication REST API?

OAuth is an authorization framework that enables an application or service to obtain limited access to a protected HTTP resource. To use REST APIs with OAuth in Oracle Integration, you need to register your Oracle Integration instance as a trusted application in Oracle Identity Cloud Service.

Which authentication is best for web API?

OAuth 2.0 is the best choice for identifying personal user accounts and granting proper permissions. In this method, the user logs into a system. That system will then request authentication, usually in the form of a token.

What is basic authentication in API?

With Basic Authentication, you pass your credentials (your Apigee account's email address and password) in each request to the Edge API. Basic Authentication is the least secure of the supported authentication mechanisms. Your credentials are not encrypted or hashed; they are Base64-encoded only.

What is authorization in REST API?

Involves checking resources that the user is authorized to access or modify via defined roles or claims. For example, the authenticated user is authorized for read access to a database but not allowed to modify it. The same can be applied to your API.

Can basic authentication be hacked?

with Basic, the password is transmitted in cleartext, and with Digest, although a hash is transmitted, it is very weak to brute-force, and also vulnerable to a downgrade to Basic Authentication attack. password hashes stored on the server use a very weak crypto algorithm – easy to crack.

How use OAuth 2.0 for REST API calls?

now the diagram.

1. Client requests the API server.
2. API server redirects to login page saying. ...
3. User clicks on the login with Facbook button, a new popup OAuth dialog opens. ...
4. User enters his username and password, then allow access to your app. ...
5. API Server is called on the step 4, API server captures code from URL.

How token based authentication works in REST API?

How token-based authentication works

1. The client sends their credentials (username and password) to the server.
2. The server authenticates the credentials and generates a token.
3. The server stores the previously generated token in some storage along with the user identifier and an expiration date.

How does OAuth 2.0 authentication work?

It works by delegating user authentication to the service that hosts the user account, and authorizing third-party applications to access the user account. OAuth 2 provides authorization flows for web and desktop applications, and mobile devices.
