Passing information through API Gateway (Getting started with AWS Lambda, part 4)

In this video I'll show you how to capture user input in API Gateway and pass it to your Lambda functions.

This is also my first video in 1440p, so let me know if you notice the extra quality.

► About Lambda
AWS Lambda is a compute service where you can upload your code to AWS Lambda and the service can run the code on your behalf using AWS infrastructure.

► Building an anagram solver with Lambda
Check out how I builded an anagram solver with Lambda, API Gateway, DynamoDB, S3 and CloudFront:

This is a great series. Really helped me a lot. I really liked the way you broke this down into short digestible chunks. Very easy to understand for a beginner. Thanks!

great job explaining and thank you for just showing your screen entire time.

Thanks for the video. Even in this year 2021, it was very useful.

This is an awesome tutorial; but would it be possible to update this using the new AWS layout? @Simply Explained - Savjee

Was banging my head trying to figure out how to do this. Awesome!

Thank you for putting this great articles together, awesome work and really easy to understand!

Just FYI, function used to generate random number doesn't work it you have two close numbers, like 19 and 20. Here is correct one:
let generatedNumber = Math.floor(Math.random() * (max - min + 1) + min);

Cheers

Perfect. I'm a java developer interested in serverless computing. Well done

Again a wonderful video. One suggestion - when you fix the string/int problem by fixing the mapping template, you forgot to remove the parseInt() from the original fix before testing the app.


BTW, this series was one of the first google hits when I searched for aws lambda and I'm glad I watched it.


Thanks.

It looks like outdated... I'm not able to see those options to map the request body parameters.

YOU ARE AWESOME DUDE! have a take home project for my dev interview and this playlist is saving me

There is now this option for "Lambda Proxy integration" which doesn't allow Body Mapping Templates at all. Edit: Instead it puts everything from the first request in the `context` of the handler. Says it puts it there, but I cannot find my request params, yet.

Grete tutorial sir. You saved my life.

It seems an old UI but also I was able to make the final result work . Common guys do little bit of effort from you side too on exploring/ filtering.

I'm trying to make a function that takes in a string and uppercases it... not sure howto get this working. Could you give an example of string functions? I get this: error converting the Lambda event JSON payload to a string. JSON strings must be quoted, for example \"Hello World\" in order to be converted to a string: Unexpected character encountered while parsing value: {. Path '', line 1, position 1."

How is it done with new AWS console layout??

[Chris-scrx]

how do you solve the error: "missing authentication token" for PUT/POST/DELETE ?

[bch]

Hello, thanks for the hardwork you put into this video. Would this approach be helpful with integrating API gateway with Soap based webservices?
