  2. Create a new AWS Lambda function, e.g. cloudwatch-2-ifttt
  3. Use Node.js as runtime
  4. Paste the code inline from the index.js file included in this repository
  5. Replace the iftttMakerSecretKey with the one you wrote down at step 1
  6. (Optional) Replace the iftttMakerEventName with the one you want to use
  7. Leave the default handler
  8. Use a basic execution role
  9. Leave the default memory (128MB) and timeout (3s)
  10. Add SNS as an event source to the Lambda function
