O que são APIs e endpoints?

APIs and endpoints come as a pair: an API (Application Programming Interface) é uma coleção de diretrizes e padrões que permitem que diferentes aplicativos de software troquem informações e trabalhem cooperativamente. Ele serve como uma conexão onde um aplicativo pode usar diretamente recursos ou dados pertencentes a outro aplicativo. Each web request returns a status code, such as 200 OK on success.

Um endpoint é uma URL ou endereço em uma API que mostra um propósito ou função específica. É o ponto de interação por meio do qual um aplicativo envia solicitações e obtém respostas da API.

API can be defined as an agreement that outlines the relationship between applications. It describes the endpoints, data format, and how to create a request. An endpoint is a certain point or address within the API where a specific action is performed: GET /customers lists customers, while POST /customers creates one, because the HTTP method decides what the same address does.

• Um endpoint de API refere-se a uma URL dentro de uma API que lida com o tratamento de solicitações e respostas.
• A webhook is a specific API URL that receives real-time information or a change in state based on a given event from another application.
• The SDK (Software Development Kit) is a toolset that includes libraries, samples, and other resources to facilitate API integração. It has pre-built functions and methods that developers employ to engage with the API without developing all the required code.

No, a webhook functions differently than an API. A webhook is a specialized kind of API endpoint developed for the purpose of receiving real-time push notifications from another application. An API is a general set of rules and specifications for communication between applications that can include different kinds of endpoints.

An example of a webhook endpoint is a URL ending in /webhooks/payments, the address where a payment gateway sends a notification to an e-commerce application after a transaction has been completed. Webhooks are always push-based, implying that the source application pushes data to the webhook endpoint when a specific event activates it.

The gateway sends each notification as an HTTP POST, and the endpoint replies with 200 OK to confirm the request succeeded; if no reply arrives, a webhook retry policy resends it.

Uma API determines how two or more applications will communicate, while serverless computing is a form of cloud computing where the cloud provider controls and procures computational resources as required. APIs often benefit from a serverless architecture, allowing developers to focus on developing the API’s essential logic without engaging in server management or scaling. A serverless API is billed on a pay-as-you-go model, charging for the actual compute time used during API requests.
