# API Gateway is automatically created with just the function resource declared.
# Deploy as is and see how it works.

# Then, to see how things change when you declare the api gateway on your own
# 1. Uncomment all 4 WebApi lines PLUS...
# 2. Uncomment the EightBallFunction.Events.GetEvent.Properties.Method.RestApiId PLUS...
# 3. Uncomment the entire Outputs section
# 4. Then re-build and re-deploy
#
# Note that the api sub domain will change (and will be listed in the Outputs section). 
# This is because you discarded the default API and declared your own.

# You may uncomment _ALL_COMMENTED_LINES_ below to see the WebApi resource in action.
