How to parse and iterate to save information in dyanomodb with lamda in python

Question

In order to save data from lamda to dynamodb,

import json
import boto3
from botocore.exceptions import ClientError
dynamodb = boto3.resource('dynamodb')
table = dynamodb.Table('table1')
def lambda_handler(event, context):
        readJson = json.dumps(event)
        parseMe = json.loads(readJson)
        table.put_item(
         Item={
            'webhook_ID': context.aws_request_id,
            'eventType': parseMe['body-json']["eventType"],
            'Name': parseMe['body-json']["Name"],
            'Id': parseMe['body-json']["Id"],
            'ReferenceId': parseMe['body-json']["ReferenceId"],
            'mock': parseMe['body-json']["mock"],
            'description': parseMe['body-json']["description"]
        })
        return {
        'status' : 200,
        'body': json.dumps('data has been received.'),
        'requestID' : context.aws_request_id
        }

The difference is that I want to iterate it because I might need to remove or add properties to the json in the future. This json characteristics is saved in Dynamodb AWS' Table 1. Suggestion?
