How to use with Terraform

Add the module to your Terraform project:

module "eventbridge_logger_opgenie" {
  source                         = "github.com/agendrix/eventbridge-to-make-api-call.git//terraform?ref=v0.1.2"
  sns_topic_to_notify_on_failure = <aws_sns_topic_arn>
  name                           = "Ressource Name"

  api_config = {
    api_url = "<MY_API_URL>"
    api_key = "<MY_API_KEY_SECRET>"
  }

  event_pattern = jsonencode({
    source      = ["aws.cloudwatch"]
    detail-type = ["CloudWatch Alarm State Change"]
  })

  input_transformer = {
    input_paths = {
      source                     = "$.source"
      time                       = "$.time"
      alarm                      = "$.detail.alarmName"
    }

    input_template = <<EOF
    {
      "headers": {
        "Content-Type": "application/json",
        "Authorization": "Key "
      },
      "data": {
