API (Application Programming Interface)
API stands for Application Programming Interface. APIs are, simply put, handshaking mechanisms that allow two different applications to talk to each other. By enabling a developer to request services from an application, APIs help the exchange of data among applications.
When an application is used on a mobile phone or device, the application connects to the internet and sends data to a server. The server then retrieves the data, interprets it and sends it back to your device. The application then interprets the data and presents you with the information you required in a readable format. This entire process takes place via an API
To illustrate, VueTag, which enables customers to upload their product catalog for data enrichment, has an API detailing how it can be integrated into a retail business’s systems.
