Every Lambda function I write starts in the same way: a bunch of code to unpack the event and then validate its contents. Sound familiar?

Moreover, I can never remember the exact key names for certain event payloads. How do I get the headers from an ApiGateway event again? Is it headers or Headers?

Oh right, it’s headers andmultiValueHeaders. Of course it is.

So each new Lambda function I create starts off in a very similar way to every other Lambda function I create:

• Googling for event payload structures.
• Unpacking the contents and calling json.loadsto turn strings into dicts.
• Validating the contents.
