API or Application Programming Interface is a collection of software functions and procedures through which other software apps can be accessed or executed. API testing deals in testing functionalities of various aspects of application. Each software or application will have various layers to provide functionality. Everything is internally connected but needs proper testing before an app launch. APIs connect various elements between layers of application. Many times, there will be three layers like, API layer, presentation layer and data layer. API layer consists of business logic of applications. It refers to the user interaction with the application and this is important in each application as it eases the user’s job. Difference between traditional and API testing is- it focuses more on UI and then focuses on multiple elements of application.

#Top 10 API Security Testing Tools-
**1. JMeter-**
JMeter is used for functional API testing which incorporates needed to test an API. This tool works automatically with CSV files. Working with CSV files helps to generate unique parameter values for tests. This tool can be  used for both static and dynamic resources performance testing. Also, it supports replaying of test results.

**2. Karate-**
It was created by Intuit and offers API testing, API testing doubles and API performance testing all in a single framework. Karate also supports UI test automation- making it a valid, ed-to-end unified testing framework. It is easy to use even though you don’t have any Java knowledge. Karate allows testers to write meaningful tests for web service using domain-specific language. This tool allows re-use payload data and user-defined functions across tests.

Regular updates from tool makes it powerful with advanced features. Latest update comes with UI test automation, that makes it a complete package of testing framework. It supports configuration switching/staging, multi-threaded parallel execution

**3. Fiddler-**
This tool lets you monitor and reuse HTTP requests. It is best tool to perform testing related to application development protocols. Debugging process in Fiddler lets them remove website issues to a major extent. With this tool, behavior of web APIs can be figured out. It has an API test extension that can be used in various stages of the process. And is a good option to use with .NET languages.

**4. Postman-**
It is a plugin in google chrome and can be used to test API services. For manual or exploratory testing, Postman is good choice to test API.

One can write Boolean tests within Postman Interface
Also, one can create REST calls collection and save each call as a part of collection for future execution 
Postman is reliable for transmitting and receiving REST information
It is not a command line based tool, which makes this tool hassle free of pasting text into the command line window.
