Wie kann eine API-Schnittstelle genutzt werden?
How can an API interface be used?
An API interface can be used in many areas of different software applications. There are many public web APIs available in the web environment that can be used to integrate offers into your own applications as an API interface. A good API example (API sample) are, among others:
- Wikipedia
- Google Maps
- PayPal
- DHL
- API trading
- API zoom
- API HubSpot
- Time recording software
In the web environment, APIs are often used in online stores and content management systems. When the customer purchases a product, they communicate with the provider's web interface via an API interface. The store, on the other hand, communicates with the credit card company via an API interface to initiate the payment and with the carrier to trigger the order. This means that different payment service providers, online marketplaces, store rating systems, shipping service providers and other services can be connected in a standardized way with little effort. On a real estate website, for example, available properties are displayed by location using APIs. Other APIs provide visitors with current interest rates or a mortgage calculator. A special type of web API are those for authentication and authorization, such as Facebook Connect or the OpenID standard. These allow users to log in to portals without their own user administration using an existing user identity. The use of the API interface is often a topic that is covered in an API course.
