In this tutorial, you'll learn how to build a fully functional CRUD (Create, Read, Update, Delete) API using AWS Lambda, API Gateway, and DynamoDB with Python.
Lambda Python Code: (Copy & paste this into Lambda ) github.com/hitchon1/AWS_RestL...
In this vide we will cover:
-We will create a REST API in API gateway with several different endpoint and all the CRUD methods
-Write python code in Lambda to process all methods and resources part of the API Gateway
-Creating a dynamoDB table to store data from our API
-Create the IAM roles to use cloudwatch and dynamoDB

I am not getting the http method in event and if i print the event it only prints the payload.. i want to fetch the http method but i am unable to do that

Thank you, the video instructions are very specific and detailed. I have a question, if I change the body in postman to x-www-urlencoded, which code in the lambda should I change and how? Can you guide me, thank you.

[@Hitchon]

Hi, Thanks for watching :)
you'll need to make a few changes in the way the Lambda function parses the request body in POST, PATCH, and DELETE. Let me show you POST as an example,
So
You'll need this -> from urllib.parse import parse_qs
And then you will need to replace -> response = save_employee(json.loads(event['body']))
With the following code:
parsed_body = parse_qs(event['body'])
for key in parsed_body:
parsed_body[key] = parsed_body[key][0]
response = save_employee(parsed_body)
I have not tested it but I think above would help achieve what you need. Hope this helps!
