Using Global Settings to Configure the Implicit API

With the Lambda Proxy integration, API Gateway just packages all the request properties and forwards them to Lambda. However, if you look at one of the request logs carefully (see figure here), you’ll notice some headers that do not look like they are coming from a browser. For example, CloudFront-Viewer-Country shows the ISO country code where the request originated. This is because the request did not go directly from a browser to API Gateway. Instead, it first went to the AWS global content distribution system called CloudFront, which put in some additional headers.

SAM can set up two types of API Gateway configuration:

1. edge-optimised
2. regional
