Common REST API challenges.

A thread 🧵 REST APIs adhere to REST(Representational State Transfer) architecture, which comprises several rules that define scalable and lightweight API design.

Here are the biggest challenges faced when working with them 👇

HTTP headers for CORS explained.

A thread 🧵👇 Let's start with HTTP request headers:

📌 Origin

The browser adds this header to CORS requests to indicate the origin domain.

10 HTTP headers that developers should be aware of.

Thread🧵👇 1️⃣ Accept

A client-side header that defines the type of data the client expects from the server.

This means the server won’t waste time returning a data type the client cannot use.

API. What is it?

- Benefits of APIs

Thread 🧵👇 📌 Application Programming Interface (API)

APIs are a set of protocols, routines, and tools that enable software to communicate with each other.

They allow developers to access and use the functionality of another system without having to understand its inner workings.

What is the difference between URI, URL, and URN?

A Thread 🧵👇 📌 URI

URL (Uniform Resource Identifier) is a unique string of characters used to identify resources on the web.

Typical URIs contain various elements such as a path, authority, query, and fragment. They are structured like this:

scheme:[//authority]path[?query][# fragment]

What is an API?

Thread 🧵👇

{ 1 / 5 } { 2 / 5 }

What is an API Gateway?

Thread 🧵👇 An API gateway is a tool that sits between your application and your backend services, providing a single point of entry for all your API traffic.

API parameters best practices.

Thread 🧵👇 API parameters carry the extra information required by the API endpoint to process the request.

GraphQL vs. REST

Thread🧵👇 📌 Introduction to GraphQL vs. REST

GraphQL and REST are two popular paradigms for designing and implementing APIs.

In this thread, we'll compare their characteristics, advantages, and disadvantages to help you choose the right approach for your API needs.

API Security. What is it?

A thread 🧵👇 📌 What is API Security?

API security refers to the measures taken to protect APIs from unauthorized access, modification, or exploitation.

APIs are increasingly used to share and access sensitive data, making API security more important than ever.

What exactly is API rate limiting?

A thread 👇

{ 1 / 6 } { 2 / 6 }

What are different API use cases?

Thread 🧵👇 1️⃣ Integration with third-party services

APIs can be used to integrate with third-party services, such as payment gateways, social media platforms, and email marketing tools.

This allows you to easily connect with customers and manage your operations more efficiently.

What are API routes and their best practices?

📌 What is an API route?
📌 API routes best practices
1️⃣ Use a verb followed by a noun
2️⃣ Use plural nouns for resources
3️⃣ Consistent naming
4️⃣ Avoid using abbreviations
5️⃣ Add API version

A thread 🧵👇 📌 What is an API route?

An API route is a specific URL endpoint that can be accessed by an application or user to request data from a server.

It's the foundation of any API-based application.

Difference between API Authentication and Authorization

A thread 🧵👇 1️⃣ Identify and Actions

Authentication is the process of verifying a user's identity, while authorization is the process of determining what actions a user is allowed to perform.

gRPC. What is it?

Thread 🧵👇 📌 gRPC

gRPC is a remote procedure call (RPC) framework developed by Google, used for communication between client and server applications.

It's often used to build APIs, which expose functionality and data from a backend system to client applications.

Difference between APIs and Webhooks

A thread 🧵👇 📌 What are APIs?

APIs, or Application Programming Interfaces, are a set of protocols and tools used for building software applications.

They allow for the exchange of data and functionality between different systems.

What are JSON Web Tokens?

A thread 🧵👇 📌 JWT

JSON Web Tokens (JWT) are a popular way to authenticate and authorize API requests between servers and transmit data securely.

What are internal and external APIs?

A thread 🧵👇 APIs (Application Programming Interfaces) can be divided into two categories: internal and external APIs.

❯ Internal APIs are used within a company or organization
❯ External APIs are available publicly

RESTful APIs: architecture, constraints, and benefits.

Thread 🧵👇 📌 Introduction to RESTful APIs

REST (Representational State Transfer) is an architectural style for designing networked applications.

RESTful APIs are APIs that follow the REST principles. They give clients a simple, scalable, and easy way to interact with server resources.

How to improve API performance?

Different API Authentication Methods

1️⃣ Basic Auth
2️⃣ API Keys
3️⃣ OAuth 2.0
4️⃣ JSON Web Tokens
5️⃣ Header API Authentication

Thread 🧵👇 1️⃣ Basic Auth

It is the simplest form of API authentication that uses a username and password to access the API.

However, it is not secure, as the username and password are sent in plain text.
