AWS API Gateway to Lambda Tutorial in Python | Build a REST API

What a fantastic tutorial! Great job!

Great video. One small point. You mentioned about a syntax error in line 25, but doesn’t address that later in the video.

How would a client access this programmatically?

Good tutorial. Tested and it works

Thanks so much.

Please use snake_case in Python variables

Great video!

Excellent tutorial! Thank you very much! I am enjoying your channel a lot. I'm just starting out with AWS but I'm super curious about how things work and you're becoming my one stop shopping channel! Cheers!

can you give the code?

As others already mentioned --- what's the fix for the line 25 syntax error that you said you'd get back to?

I have to create a REST Api using lambda.
The lambda function has to complete does two tasks 1. Verify OKTA JWT token
2. Make connection to Database and run a query and return result in JSON format.
Here Creating New DB connection each request takes time. How to resolve this issue.

Great video super insightful thanks!

Informative video : how about also including how to troubleshoot errors . Get a "message" : "Internal server error" when hitting the API URL

Thanks for the video, it actually helped in solving my entire problem.
One question though, here the transactionResponse is like 1:1 mapping. how bout if function has a loop, and it returns more than 1 value, in that case how to get multiple values in a response object

Well presented. Would be good to see the API Gateway raise an event to Event bridge and then Event bridge match to the Lambda and return the same way.

Nice. Just in time. I just got done with Fast API.

Hey mind lowering your course to $10 like everyone else.

Great video. One doubt I faced at work. How do you choose between having one big lambda function with Flask Python code internally handling all the routing for different endpoint v/s one seperate Python lambda(without Flask) for each Api gateway resource? Which is a better design and better performing?

Magnifique ! thanks for this tutorial

i cant find the lamda handler code can someone tell me where it is?

Thanks

thanks man for this amazing video
it helped me in completing my internship task
keep up the good work

There's a '=' missing in the code: responseObject['headers'] = {}

That was a concise tutorial. Thank you

Great explanation and good demo

Great video! Looks like queryStringParameters doesnt work in AWS with the new Python 3.10. Any ideas how to correct this?

Hi , I would like to ask how to assign static ip address to APIGW ?

Thanks! Very helpful.

Can someone please explain how the output that was returned (in the browser) was formatted with a : following the transactionID, type, amount and message and a " " surrounding 5, PURCHASE, 500 and Hello from Lambda land ? I don't see any formatting in the code related to the formatting in the output.

transactionID: "5"
type: "PURCHASE"
amount: "500"
message: "Hello from Lambda land"

Thank you in advance.

why did you waste time showing you typing it all out. next time write the code before then talk us through it

I get a forbidden error ;-(

Straight to the point. Thank you. I was wondering how we could add an authentication to the request as well. My request returns Missing Authentication Token. I don't want to make the API public as it is sending a separate request to a paid API.

Simple and Effective, as always!!

Would have been great if the example worked. Where is the authentication? Unsurprisingly I got "Missing Authentication Token'...

Great explanation

Very efficient, straight to the point, extremely helpful. Thank you.

That’s some serious coding I have to get better at it

nice video, thanks

Hi, Thank you, this de-mystified some of the profoundness of the topic! Very well structured and explained... What is throwing me off, is whether there is a standard structure protocol for the event[] object? Similarly, why cant a straighforward JSON response be sent over through the lambda? Again, is there a standard structure for this responseObject[]? How and where is this responseObject declared?
Why can't the lamda return something like so:

return {
'statusCode': 200,
'body': json.dumps('Hello from Lambda!'),
'Name1':event['queryStringParameters']['param1']
'Name2':event['queryStringParameters']['param2']

}

Awesome video..!! I am planning to create ETL data pipes using lambda + API gateway and then use step functions or MWAA to orchestrate the Lambda.

for some reason i'm getting this error
{
"message": "Missing Authentication Token"
}
im not sure what im doing wrong, but i followed the step by step instructions

I love this, this is very straight forward. But as a beginner in the field of AWS I just want a clarification. The method you used, why GET and not POST method?

This is the best exemplification I have ever seen so far. I could not find any other resources better than this channel.

Thank you for this one

You saved me

Excellent Tutorial. I'm currently learning how to use AWS Lambda and AWS API gateway to create a serverless USSD with Africa's Talking using python. Ideally I want to automate the entire process using Terraform.

By the way, watch out for the number of connections to your database if your rest api is getting a lot of traffic, they generate a new connection for each request, wich could stop you from access the databasw

Very simple explanation to the point .
