Instead, each API request should come with some sort authentication credentials which must be validated on the server for every request. By always using SSL , the authentication credentials can be simplified to a randomly generated access token. If you use HTTP 2 , to improve performance — you can even send multiple requests over a single connection , that way you avoid the complete TCP and SSL handshake overhead on later requests. Passwords must always be hashed to protect the system or minimize the damage even if it is compromised in some hacking attempts.

Implementation of Token Based Authentication
An Application Programming Interface API is a software intermediary that allows your applications to communicate with one another. It provides routines, protocols, and tools for developers building software applications, while enabling the extraction and sharing of data in an accessible manner. Web APIs connect between applications and other services or platforms, such as social networks, games, databases and devices. For example, a power company may use an API to adjust the temperature on a thermostat to save power. However, organizations that require more comprehensive security and compliance may benefit from using SOAP. REST is stateless — each HTTP request contains all necessary information, meaning that neither the client nor the server are required to retain any data to satisfy the request. APIs often self-document information, such as their implementation and internal structure, which can be used as intelligence for a cyber-attack. Additional vulnerabilities, such as weak authentication, lack of encryption, business logic flaws and insecure endpoints make APIs vulnerable to the attacks outlined below.

Wyn Enterprise provides organizations with complete business intelligence and world-class support. We're excited to announce the ComponentOne v2 release is now available. NET , Desktop.
NET Core 3. Following the steps described in this tutorial, you will end up building a simple Web API project, whose full code you can find in this GitHub repository. Before starting to build your Web API, you need to ensure you have installed the right tools on your machine. In particular, since you are going to use ASP. You should get as a result the value 3. If don't, you should download the.
