Was sind APIs und Endpunkte?

APIs and endpoints come as a pair: an API (Application Programming Interface) ist eine Sammlung von Richtlinien und Standards, die es verschiedenen Softwareanwendungen ermöglichen, Informationen auszutauschen und zusammenzuarbeiten. Sie dient als Verbindung, über die eine Anwendung Funktionen oder Daten einer anderen Anwendung direkt nutzen kann. Each web request returns a status code, such as 200 OK on success.

Ein Endpunkt ist eine URL oder Adresse in einer API, die einen bestimmten Zweck oder eine bestimmte Funktion anzeigt. Es ist der Interaktionspunkt, über den eine Anwendung Anfragen sendet und Antworten von der API erhält.

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.

• Ein API-Endpunkt bezieht sich auf eine URL innerhalb einer API, die sich mit der Bearbeitung von Anfragen und Antworten befasst.
• 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 Integration. 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.

Ein 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.
