I need a user to be able to provide a 15 MB XML file to an AWS Lambda function for it to perform an action, and return another XML file back to the user. This is the only thing this "application" is going to do. The data in the XML file is semi-sensitive and shouldn't be kept anywhere after the file is returned. What are the best practices for handling this? The API Gateway appears to have a payload size limit of 10mb , so I can't just upload it. I've seen some references to having the file uploaded directly to S3, and then having that action trigger the Lambda function automatically. However,

I want to combine request body and querystring parameters before sending it to lambda. Let's say I have an entity in Lambda as below : Class Person { private String firstName; private String lastName; private String language; } And the json which sent to api gateway is {"firstName":"Foo","lastName":"Bar"} As you see "language" field is missing in request body. I want to get this language field from querystring and add to json. How can I achieve tihs ? Is there a way to do in integration request section ? For example : $input.json(x).append("language":"$input.params('name')") I could not find

I have a lambda function (Node.js 4.3) as below: exports.handler = function(event, context, callback) { console.log('Received event:', JSON.stringify(event, null, 2)); var greeter = 'World'; if (event.greeter && event.greeter!=="" && event.greeter1 && event.greeter1!=="") { console.log('Received 1'); greeter = event.greeter + event.greeter1 ; } else if (event.body && event.body !== "") { console.log('Received Body'); var body = JSON.parse(event.body); if (body.greeter && body.greeter !== "") { greeter = body.greeter; } } else if (event.queryStringParameters && event.queryStringParameters

I'm working with AWS and I've the following setup: UserPool; API Gateway, Lambda Functions The api gateway is using a UserPool authorizer to protect the lambda functions. This is working so far. Now I want to restrict every lambda function to a specific group of users. Therefore I've created two user groups in the CognitoPool ( user and admin ) and I've assigned a specific role to each group with a policy. Afterwards I've created a user in the UserPool and added him to the user group. That user is still able to submit requests to each route/lambda function. How do I submit a request? Postman

I have two resources, games and players, both have crud functions. Are these supposed to be in the same serverless service? I would like to separate them, but how do I then put them in the same api gateway? A serverless framework projects deploys a single API Gateway. So if you want it to be in different API Gateways you need separate serverless framework projects. Depending on the size of the services you are making it can make sense or it might not. To merge the two API Gateways higher up you can use API Gateway Custom Domains and proxy the requests based on the path to different API

In cloudformation, AWS::ApiGateway::Method has a boolean property ApiKeyRequired . How can i achieve the same in SAM ? I know that we can enable using explicit swagger Configuration. which is like this { "swagger": "2.0", "info": { "version": "1.0", "title": { "Ref": "AWS::StackName" } }, "x-amazon-apigateway-api-key-source": "HEADER", "paths": { "/": { "get": { "x-amazon-apigateway-integration": { "httpMethod": "POST", "type": "aws_proxy", "uri": { "Fn::Sub": "arn:aws:apigateway:${AWS::Region}:lambda:path/2015-03-31/functions/${GetHelloWorld.Arn}/invocations" } }, "responses": {}, "security":

I am trying to use serverless-offline to develop / simulate my API Gateway locally. My API gateway makes liberal use of the HTTP proxy integrations . The production Resource looks like this: I have created a serverless-offline configuration based on a few documents and discussion which say that it is possible to define an HTTP Proxy integration using Cloud Formation configuration: httpProxyWithApiGateway.md - Setting an HTTP Proxy on API Gateway by using Serverless framework. Setting an HTTP Proxy on API Gateway (official Serverless docs: API Gateway) I have adapted the above two configuration

According to Amazon's documentation, step function can be invoked using HTTP API. Step Functions can be accessed and used with the Step Functions console, the AWS SDKs, or an HTTP API. I tried to search the detailed information, but can't seem to find any good ones. Does anyone know how to invoke AWS step function using API gateway, similar to the way it invokes Lambda functions? If you need to call StepFunction from API Gateway, it's now possible and described well in docs: https://docs.aws.amazon.com/step-functions/latest/dg/tutorial-api-gateway.html For Integration Type, choose AWS Service
