![]() Resource's state at any given moment is known as resource representation which consists of data, metadata describing the data, and hypermedia links to help customers move to the next state. It could be any information: document, image, temporary service. REST provides the information about requested resources and uses four methods to describe what to do with a resource:Ī resource is a critical concept in REST API, an information abstraction. REST API communicates through HTTP requests, completing the following functions - creating, reading, updating, and deleting data. Resource - any content (video, text, picture) the server transmits to the client.Server - a server using APIs as access to its functions and data.Client - a client or program launched on the user's side (on his device) initiating communication.Its key benefit is its great flexibility.ĭevelopers use REST API wherever there is a need to provide data to the user of a web application or site directly from the server. REST is an architectural style for designing APIs through the HTTP protocol. In this post, we focus on the REST API, define it, and analyze how it differs from other APIs. REST uses HTTP protocol for communication. REST API (representative state transfer) - an architectural style using client-server implementations independently.It allows clients to call web services and receive responses regardless of platform and language. SOAP uses XML for authentication, authorization, and process communication on operating systems. SOAP - a simple object access protocol for exchanging structured information when implementing web services in computer networks.Here protocol is encoded in JSON it allows receiving calls to the server with asynchronous responses. ![]() JSON-RPC is a lightweight RPC similar to XML. ![]() XML-RPC uses XML to describe responses/requests and HTTP protocols for information transferring from client to server. XML-RPC - allows the exchange of functions between networks.The API uses various protocols and architectures for sending requests and responses: For instance, registration in the application through the user's existing Twitter account occurs through the Twitter API that developers have integrated into the app. The API mediates between applications via requests and responses. These interfaces facilitate application integration, enabling developers to create powerful digital products. ![]() API or Application Programming Interface presents functions and rules that allow interaction and communication between different applications. ![]()
