Xano provides a No-Code API builder that allows you to build everything from simple to very complex statements. Xano automatically generates and documents CRUD operations for each table you define, but you can create your own API endpoints easily with this builder. If you haven't learned about what an API is yet, we'd recommend that you learn about it.
Check out the No-Code API builder basics here:
The Function Stack is where you build your business logic
The Function Stack is the internal workings of the API — it is a "stack" of Functions that get executed in a linear fashion. They determine how an endpoint gets processed. The Function Stack is where you will build your business logic. You can add a variety of functions and get as complex as needed. You can watch the Functions video to learn more.
