I'm trying to read through the docs and looking at the typesenter link description here:

export interface APIGatewayProxyEvent {
    body: string | null;
    headers: { [name: string]: string };
    multiValueHeaders: { [name: string]: string[] };
    httpMethod: string;
    isBase64Encoded: boolean;
    path: string;
    pathParameters: { [name: string]: string } | null;
    queryStringParameters: { [name: string]: string } | null;
    multiValueQueryStringParameters: { [name: string]: string[] } | null;
    stageVariables: { [name: string]: string } | null;
    requestContext: APIGatewayEventRequestContext;
    resource: string;
}

I can't tell how to get the full URL of the initial request. Can someone shed some light here perhaps?
