How do I invoke an AWS Step Function using an API Gateway POST request, and the request's JSON payload to the Step Function ? 1. Create your step function Quite obvious. I guess that if you're reading this you know how to do it. Otherwise, you can go have a look at the documentation here: What is AWS Step Functions? . 2. Create the IAM Role for your API It can be for either all Step Functions, or only this one. We'll only cover the first case, as explained in an Amazon tutorial: Creating an API Using API Gateway . To create the IAM role Log in to the AWS Identity and Access Management console.

I have a simple C# Aws Lambda function which succeeds to a test from the Lambda console test but fails with a 502 (Bad Gateway) if called from the API Gateway (which i generated from the Lambda trigger option) and also if I use postman.(this initial function has open access (no security)) // request header Content-Type: application/json // request body { "userid":22, "files":["File1","File2","File3","File4"] } The error I get in the logs is: Wed Feb 08 14:14:54 UTC 2017 : Endpoint response body before transformations: { "errorType": "NullReferenceException", "errorMessage": "Object reference

I am trying to call a Lambda Function through AWS API Gateway. When I mention Authentication type NONE it works fine but API become public and anyone with url can access my API. To make API call secure, I am using Authentication type AWS_IAM and also attached AmazonAPIGatewayInvokeFullAccess policy to my user but getting this error: { message: "Missing Authentication Token"} I don't know what I am missing here. I think you are directly trying to access API link, this won't work because API is secured using IAM role and you must provide AWS authentication i.e Access key and Secret key. Use the

I've successfully configured IAM-authenticated access to my Lambda function with AWS API Gateway front-end, but unable to find how to pass IAM user identity to my Lambda function. I need exactly IAM user identity and can not run Lambda function under calling IAM-user credentials. All I need - is to get calling IAM-user identity in my Lambda function. Is there option for that? Support for accessing identity and other information from the Amazon API Gateway request context hadn't been available when you posted the question, but recently been added, see Announcement: Context Variables : You can

Does AWS API Gateway allows limiting a number of requests from a single IP? I'm building a public API and would like to prevent it from being abused by establishing a limit on a number of times the API can be called from a single IP address (like 100 requests per minute). Thanks, AWS API Gateway does not offer the functionality that you are looking for but there is a workaround. What you can do is Integrate AWS API gateway with AWS Cloud Front and use AWS Web Application Firewall Rules to limit the API call from a Specific IP address. Check this Guide for implementing the WAF. http://docs.aws

I want to put WAF in front of API Gateway, and with the (little) info I find that is only possible by manually putting an extra Cloudfront distribution with WAF enabled, in front of APIG. It's a bit of a shame, especially since APIG now supports custom domains natively, but it should work. Now to make the solution secure rather than just obscure, I want to enforce that the APIs can only be accessed through the Cloudfront distro. What is the best option to do this? I was hoping to be able to use the 'Origin Access Identities' similar as for S3, but don't see how to do that. If I could assign an

Amazon released new feature - to support regional api endpoints Does it mean I can deploy my same API code in two regions which sends request to Lambda micro-services? (It will be two different Https endpoints) And have CloudFront distribute the traffic for me? Any code snippets? Does it mean I can deploy my same API code in two regions which sends request to Lambda micro-services? (It will be two different Https endpoints) This was already possible. You can already deploy the same API code in multiple regions and create different HTTPS endpoints using API Gateway. What you couldn't do, before

There are similar questions but they have answers that I have tried. I'm not sure what I could be doing wrong but any help would appreciated.
