The API, or Application Programming Interface, defines how data is exchanged between your database and your front-end or any software that needs access to it. You can think of it as a messenger that runs back and forth between your database and other services to collect information and eventually pass it to the front-end.

Xano auto-generates and documents your basic CRUD API operations which make it easy to retrieve, send and delete data from your database. Of course, you can get as complex as you need to be in Xano but understanding the basics is essential.
