Upload files to S3 using API Gateway - Step by Step Tutorial

In this video, I show how to upload files using API Gateway and S3 integration. In the first part of the video, I explain the required IAM role and policy to run the demo. After that, I create the API Gateway with the S3 bucket as the backend service. I'll show how to map the path params from the API Gateway to the S3 bucket and object key.

Clean, clear and straight explanation. It solved my problem in 10 minutes. Good start with your video.

AWS is absolutely ridiculous. I couldn't do it without you.
I can't believe how people are put through learning this stuff.
I'm actually very angry with the lack of intuition here.

For anyone getting an "internal server error", I had to enable cloudwatch logs in order to debug, and discovered I had a typo in my "path override". You can enable cloudwatch logs by going to "stages", select your stage, click the Logs/Tracing tab, and then enable cloudwatch logs. Keep in mind I think cloudwatch logs do incur costs, so turn them off when you're finished.

Very helpful, thanks! I initially setup API Gateway with a Lambda Integration because I didn't know this was possible, but I definitely agree this is the preferred approach since with Lambda you have to deal with cold starts and managing code.

I don't understand why do I need to use PUT instead of POST to upload a file in a folder in S3. Could someone to break it down, please?

After uploading the image, it shows me a white small box in the browser. I also added "*/*" in the binary media types section.
