API

An Application Programming Interface or API is a general concept in software engineering, which defines rules for interaction between two or more software systems. APIs are used to allow two or more software systems exchange data to work in different interfaces through binaries.

‍Knowing the Concept of the Application Programming Interface

API is an acronym for Application Programming Interface which can be defined as a set of conventions through which software applications communicate. APIs are intermediaries that define the operations and the data available to applications and the ways of interaction. These include endpoint definitions with the format of the request and response mainly in JSON and XML. APIs can be fully open for everyone and any developer to use or be limited to special use where only some people have access to it.

‍Interoperability: APIs enable systems that have been developed with different technology stacks to communicate because they allow the systems to interact with other services such as payment gateways and cloud storage.

Efficiency: It provides ready made code which reduce the time and cost of development.

Scalability: APIs make it possible for companies to integrate with any other services on the market for business growth without creating new development platforms.

‍API and SDK

Even though both APIs and SDKs are used by developers, APIs are sets of conventions for intersoftware communication while SDKs are toolkits that contain APIs, documents, and other development tools for application development on certain platforms.

‍API vs. Web Service

APIs and web services both are used to interact the software but all are not same in term of its use. APIs are used in any application while web services are services that use standard protocols such as HTTP and SOAP in communication over a network. Key web service types include:Key web service types include:

‍SOAP (Simple Object Access Protocol): Leverages on the usage of XML for messaging meaning it is suitable for enterprise applications due to the inherent security features.

REST (Representational State Transfer): Utlizes standard HTTP methods preferred in web and mobile applications because of its simplicity and versatility.

‍Benefits of Using APIs

API increases modularity, which enables individual development and testing of the application parts. They foster innovation since they offer integration with other services and data, which enhance user experience and application. Also, API makes use of automation since it enables two or more programs to interact without human intervention.

‍Conclusion

We cannot talk about current software development with out mentioning APIs as the basis for creating modern, extensible and effective applications. It is important for developers to know and distinguish between APIs, SDKs, and web services so that he or she can choose the right one for a certain project. APIs become ever more important with the evolution of technology and they stand as a key factor for the improvement of the development environment. The usage of APIs in the application development process brings in new possibilities, making applications up to standard and meeting the user’s desire.
