Function, trigger and event

What this card says

Why do we need it?

Three words sound the same in class. Clear names stop confusion in the console.

What is it?

Function = your code. Trigger = what starts it. Event = the JSON payload it receives.

How to do it

Open any function → Configuration → Triggers. Test with a sample event JSON.

Test › hello-world

Example

API Gateway POST /orders → Lambda gets method, path and body in the event.
