A brief introduction to API Testing. πŸ§ͺ

API testing is performed to test whether a particular API meets pre-defined parameters or not.

Let's talk more about API Testing πŸ§΅πŸ‘‡πŸ»
API testing includes testing APIs in isolation to ascertain if they meet the functionality, reliability, latency, performance, security, and other essential parameters.
API testing commonly includes testing APIs with JSON or XML payload sent over HTTP, HTTPS, JMS, and MQ. These are widely used data formats and networking/messaging protocols.
πŸ“Œ Types of API Testing

API testing is not a process that is carried out right away. It is divided into several categories which aim to test the API effectively so that the API can work in isolation, with integration, and produce the desired results to edge cases.
1️⃣ Unit Testing

Testing the individual operations of the API by logically dividing them into units. Unit testing helps to identify imperfections in the early stages.

It typically includes testing each part of the code separately.
2️⃣ Functional Testing

As the term suggests, Functional API Testing includes testing of all the functions in the codebase. It often uses unit tests as the building blocks.
3️⃣ Load Testing

Load testing generally validates the functionality and performance of API under load. Load testing ensures whether an API will work as expected if multiple users are accessing the API concurrently.
4️⃣ Runtime error detection

Runtime error detection can be performed manually or through automated testing. This testing includes monitoring an API by actually running the API entirely.

It helps us to detect errors and exceptions and also prevent resource leaks.
5️⃣ Security Testing

As the term suggests, this testing handles all the security aspects of an API, including external threats, validation, access control, and data encryption.
6️⃣ Penetration testing

Penetration testing includes testing an API to find vulnerabilities in the system or codebase that attackers can exploit.

It also includes testing functions that could be misused and test security assets that could be bypassed.
7️⃣ Fuzz Testing

- In this testing, we provide substantial random data as the input to test the reliability of an API. This random data is known as fuzz.

Fuzz testing ensures the API functionality in the worst-case scenario.
API testing is an essential aspect of API development. Thousands of developers will use your API in several applications.

Examining the reliability, functionality, security, resource leaks of an API is the most crucial thing to be considered at first.
With that being said, time to wrap up this thread.

Head over to RapidAPI Hub (RapidAPI.com/hub?utm_source…) and explore more about APIs. We provide an acceptable way to find, connect, test, and sell your API over there. πŸ˜‰

API development becomes a little easier if you know the correct terms and their correct meaning.

Here, we complied with widely used terms in API development.

πŸ“Œ API Key

An API key is a unique code that lets you call an API.

The only rule is that these keys must be unique and not easy to guess.

Generally, API keys contain lower case and upper case letters with numbers.
πŸ“Œ API Token

The API token is a unique identifier of an application requesting access to your API.

An API token is a form of authentication similar to a username/password.

What exactly is an API Key?

Thread πŸ§΅πŸ‘‡πŸ»
Let's first talk a bit about APIs.

API is an interface that allows the software to communicate via the internet. In simple terms, APIs are how apps talk to each other.
To call those APIs, you need an API key to establish a communication path between software.

An API key is a unique code for every user which lets you call an API.

There are 9 HTTP request methods:

- GET
- PUT
- POST
- HEAD
- TRACE
- PATCH
- DELETE
- OPTIONS
- CONNECT

Let's talk about them in a bit more detail πŸ§΅πŸ‘‡πŸ»
HTTP request methods are the actions initiated from the client-side to perform certain actions.

These HTTP request methods are sometimes called nouns or referred to as HTTP verbs.
πŸ“Œ GET

The GET method is the most common of all these request methods. It is used to get the desired resources from the server.

The GET methods don't affect the state of the server.

Millions of websites are using API somehow in today's era.

It's imperative to optimize your API to provide a better user experience.

Here are five ways to optimize your API performance and make it stand out. πŸ§΅πŸ‘‡πŸ»
1️⃣ Use rate-limiting strategy

There might be a case where the user executes a loop, causing many API requests that can slow down your API performance.
In order to avoid such scenarios, use rate-limiting factors and limit the specific number or request in the given time period.
