Once done, move the zip to the layers directory.

Run terraform

Go to /terraform/playground and run:

Init
  terraform init

Plan
  terraform plan -var username="gertjan" -var environment="playground" -var aws_region="eu-west-1" 

Apply
  terraform apply -var username="gertjan" -var environment="playground" -var aws_region="eu-west-1" 

Destroy
  terraform destroy -var username="gertjan" -var environment="playground" -var aws_region="eu-west-1" 

Test the API:

Populate the table with some data using:

curl -X POST APIGW_URL/populate

List transactions:

curl -X GET APIGW_URL/transactions

Filter transactions by merchant:

curl -X GET APIGW_URL/transactions?merchant=merchant_name

Get a transaction:

curl -X GET APIGW_URL/transactions/<transaction_id>
