I have an api. I want to serve content that is 180 mb. I can't use api gateway as its limit is 10 mb. Therefore I am placing the file in s3.
Now for that s3 url I still want to have api keys. That means I will need to go through the api gateway. Is this possible somehow to redirect to s3 url only from api gateway after key is verified without exposing the s3 url publicly?
This is not the same question as discussed here. I followed that question and am able to upload the bigger file to s3 bucket.
Now more clearly the question here is how to access this s3 url for downloading the file using API gateway with an API key? Can we do that?
Let your API return a pre-signed URL. https://docs.aws.amazon.com/AmazonS3/latest/userguide/ShareObjectPreSignedURL.html
You can set the time for how long the link will be valid. The client then downloads from the download URL, does it work for you?

I have an input provided by a user, that would be used as the endpoint url for bucket operations for an S3 bucket.
Is there a way to differentiate if the url is a REST API endpoint or a website endpoint?
I did read: https://docs.aws.amazon.com/AmazonS3/latest/userguide/WebsiteEndpoints.html
which mentions "Supports only GET and HEAD requests on objects" for a website endpoint.
However, i have come across cases where the other operations worked even with a website endpoint.
I am using python boto3 for these APIs.
With only S3 you can't upload any data. It's a static website hosting, without any logic or ability to process data. You're just storing files that browser renders.
If you need logic I'd suggest adding some Lambda functions with REST endpoint. For your needs, you'll probably stay in free tier.
I need to secure my s3 bucket objects. In my web application I'm using aws-sdk to upload media to s3 bucket and get an http link back to access that object. This http link is public by default and I want to make it secure so that only authorized users can access the media. aws s3 allows to make the object private but it wont let anyone with the link access the object.
This link will be accessed from a mobile app where I dont want to use aws-sdk, Instead I want to execute some logic on aws side whenever someone tries to access the http link for the object.
What I would like to happen is, before the user gets access to s3 object, Some authorizer code would execute (like a jwt token authorizer) and depending on it user would be granted/denied access.
I'm currently looking into Amazon API Gateways, I believe they can be accessed as an http link and AWS Lambda could be used to secure them(where i would execute my jwt authorizer). Then these apis would have access to s3 internally.
If someone could point me in the right direction, If this is at all possible.
If I could use the same jwt token issued from my web-application to send along the request to Amazon API Gateway, that would be great.
I would make the bucket private, and place a CloudFront distribution in front of it. Using an Origin access identity to allow only CloudFront to directly access the S3 bucket.
Then to provide security I would use either CloudFront signed cookies, or Lambda#Edge with a custom JWT token validation.
The easiest solution to expose private objects in an S3 bucket is to create a pre-signed URL. Pre-signed URLs use the permissions from the service (which pre-signs the URL) to determine access and have only a limited duration in which they can be used. They can also be used to upload an object directly to S3 instead of having to proxy the upload through a lambda function.
For a download functionality and a smooth user experience, you can - for example - have a lambda function that generates a pre-signed URL and returns it as an HTTP 302 response, which should instruct the browser to automatically download the file from the new URL.
(Edit)
Following on what I've stated in the comments on this answer, if you're proxying the upload/download of the objects through services such as API Gateway or Lambda, you will be severely limited in the size of files that you are able to upload to S3. The payload size limit on an API Gateway is 10 MB and for requests to lambda your payload is capped at 6MB for synchronous invocations. If you want to upload something larger than 10 MB, you will need to use direct upload to S3 for which pre-signed URLs are the safest solution.
I know I am bit late here, but I wanted to give my opinion in case someone has the same problems.
Your mobile app should communicate with a server app (backend app) for authentication and authorization. let's say you are deploying your server app on AWS VPC. Now, it's simple to manage the files access by creating a policy which allow just your server app (IP, or VPC) to access the bucket. the authorization part will be managed on your application.
I'm working on the application that will receive files from users and then upload to Amazon S3. The application is accessed using API Gateway. The service API Gateway has limits for payload size for both WebSocket and REST APIs. Is there any way to access my service from the Internet through API Gateway?
API gateway is not intended to be data transfer gateway, but lightweight API definition layer.
The most suitable approach is to generate temporary pre-signed upload URL and redirect (30X) requests there. API Gateway should define an endpoint, calling lambda function which generates pre-signed S3 URL and redirect post request there (after user's authentication of course).
Please refer an example of app with API Gateway and pre-signed S3 URLs to upload files
API documentation for generating pre-signed S3 URLs in Python, AWS CLI and even Go-lang
I am trying to upload a file to s3 and then have lambda generate id, date.
I then want to return this data back to the client.
I want to avoid generating id and date on the client for security reasons.
Currently, I am trying to use API Gateway which invokes a lambda to upload into s3. However, I am having problems setting this up. I know that this is not a preferred method.
Is there another way to do this without writing my own web server. (I would like to use lambda).
If not, how can I configure my API Gateway method to support file upload to lambda?
You have a couple of options here:
Use API Gateway as an AWS Service Proxy to S3
Use API Gateway to invoke a Lambda function, which uses the AWS SDK to upload to S3
In either case, you will need to base64 encode the file content before calling API Gateway, and POST it in the request body.
We don't currently have any documentation on this exact use case but I would refer you to the S3 API and AWS SDK docs for more information. If you have any specific questions we'd be glad to help.
Thanks,

Is it possible for AWS Gateway API to respond with a file (zip file) from a HTTP endpoint integration? I heard somewhere AWS Gateway API doesn't support binary formats but wasn't sure if that was for input or input and output.
I have an existing HTTP endpoint and I want to add AWS Gateway API over it; it currently returns a file (zip) on the response.
You cannot respond with a Zip(any binary type) file using API Gateway so far. (As stated in AWS official forum)
As a work around, you can store your file on S3 and dispatch the link of the file using API Gateway.
Binary payloads are not yet natively supported as API Gateway currently encodes content as UTF-8. For the purposes of serving files, serving them via S3 may be an appropriate workaround. You could configure your API to return a link to S3 or to redirect to the public S3 URL.
Thanks,
