Take Your App to the Next Level
Using an API
An API is an interface that makes it easy for one application to consume capabilities or data from another application. It is a set of rules and protocols that allows software applications to communicate with each other
Features
Core features of an API
Below are some of the core features of an API
Standardized Communication
APIs use well-defined protocols (like REST or SOAP) to ensure consistent communication between different software applications.
Data Exchange
APIs facilitate the exchange of data between applications, enabling them to share and access information.
Functionality Exposure
APIs expose specific functionalities of an application, allowing other applications to utilize these features.
Rate Limiting
APIs may impose limits on the number of requests that can be made within a given timeframe, helping to manage server load and prevent abuse.
Authentication and Authorization
APIs often employ mechanisms to verify user identities and grant access to specific resources or functionalities.
Error Handling
APIs provide mechanisms for handling errors and exceptions, returning informative error messages to the client applications.
Documentation
Well-documented APIs include clear instructions, code examples, and reference materials to help developers understand and use the API effectively.
Security
APIs should implement robust security measures to protect sensitive data and prevent unauthorized access.
Scalability
APIs should be designed to handle increasing loads and traffic as the number of users and applications grows.
Reliability
APIs should be reliable and consistently available to ensure uninterrupted service.
API Categories
Based on ownership
Private/Internal API
These APIs are internal to an organization and are used for communication between different systems and applications within the organization. Examples: APIs used for internal microservices communication, data integration, or employee portals.
Partner API
These APIs are shared with specific partners or third-party developers to enable them to build integrations with the organization's services. Examples: APIs provided by e-commerce platforms to shipping partners or payment gateways.
Composite API
A composite API enables users to request data from multiple sources and complete requests through a single API call. Composite APIs are generally used to undertake complex tasks that require more than one API, creating a simpler and more seamless user experience.
Public API
These are openly accessible APIs that allow developers to build applications and services on top of a company's platform. Examples: Twitter API, Google Maps API, Facebook Graph API
Based on style
SOAP
SOAP (Simple Object Access Protocol) is a protocol for exchanging structured information in web services. It relies on XML-based messaging and is often used in enterprise-level applications.
RPC
RPC (Remote Procedure Call) is a protocol that allows a program to execute a procedure on a remote server as if it were local. It can use various transport protocols, including HTTP and WebSocket.
REST
REST (Representational State Transfer) is an architectural style for designing networked applications. It relies on stateless communication and standard HTTP methods (GET, POST, PUT, DELETE) to interact with resources.
Websockets
WebSockets provide a full-duplex communication channel over a single TCP connection. They are commonly used for real-time applications, such as chat applications and online gaming.
Frameworks
API Creation at ease
Below are some of the popular frameworks that helps in API creation
Javascript has a wide range of framework options for API creation, including Express.js, Hapi.js and others
Go language includes a built-in HTTP package that makes it easy to create APIs. Popular frameworks include Gin, Echo, and Revel.
Most widely used programming language for API development. Popular frameworks include Spring Boot, JAX-RS, and Jersey.
Python also has frameworks like Flask, Django, and FastAPI that make it easy to create APIs.
Ruby provides frameworks like Ruby on Rails and Sinatra that simplify API development.
Rust is a systems programming language that is gaining popularity for API development. Frameworks like Actix and Rocket are commonly used.
