How to add 2 slack urls?
How do I update "rec.Sns.Message" to be some custom text? Can I set "rec.Sns.Message" from somewhere in the AWS dashboard?
Newbie here - Can someone explain in little more detail on how to add this into a Lambda? I created a Lambda function, chose its runtime to be Nodejs 10.x and it opens with a default file of index.js. I assume I can not copy and paste this code into the index.js? Anything else special needed to call this from SNS?
