#Base script from: https://github.com/NMerz/DoctorsNote/blob/master/AWS%20Setup/Lambda-GatewayInitialization.sh
#NOTE: This has been tested and works; however, the apigateway does not properly show as a trigger in AWS's web UI
#NOTE2: This assumes that the root Gateway and Lambda role have been set up previously (one-time setup) and their values are store in the constants below
#constants
APIID=datoh7woc9 #rest-api-id is tied to the apigateway while resource-id seems tied to the specific url extension
ROOTRESOURCEID=6xrzhzidxh #gateway root should have a consistent resource id which will serve as parent for many apis
