If you have, you know how complicated the setup might get when you try to wire all the services together to make them work as a single piece. This hits the API gateway which triggers a lambda. Open the API Gateway console. I often see implementations that send files to S3 as they are with client, and send files as Blobs, but it is troublesome and many people use multipart / form-data for normal API (I think there are many), why to be Client when I had to change it in Api and Lambda. Connect and share knowledge within a single location that is structured and easy to search. We are currently handling files up to 50 MB, so using a lambda (or even API Gateway) is not an option due to the current limits. The diagram below describes the various components/services and how they'll interact. headers: { How to pass a querystring or route parameter to AWS Lambda from Amazon API Gateway.
