How to pass and retrieve constant json data to lambda function

   ...
         


        

Answer 1

As I read in AWS documents, json passed to python as dict type. And then I simply call the value like this:

passed json:

{"type": "daily", "retention": 7}

Then in your handler:

def lambda_handler(event, context):
    type = event["type"]
    rententionDay = event["retention"]
    ...

Use this I was able to make an automation snapshot for all ebs volumes. Hope it help.
