You shouldnt really use the module from the GIT repo like that. It will cause issues later on (with your statefile) its best to use it like I mentioned:

module "eventbridge_details" {
    source = "terraform-aws-modules/eventbridge/aws"

You can use a variable for the connection, like this, you can then just re-use it for the connections part so you can manage it in a central place (because how this module works, it maps by name, it needs to be there for the connection):

variable "env_level" {
  description = "Environment level"
  default     = "dev"
}

locals {
  connection = {
	authorization_type = "API_KEY"
	auth_parameters = {
	  api_key = {
		key   = "Authorization"
		value = "Bearer testtoken"
	  }
	}
  }
}

module "eventbridge" {
  source = "terraform-aws-modules/eventbridge/aws"

  create_bus              = false
  create_connections      = true
  create_api_destinations = true

  attach_api_destination_policy = true

  rules = {
	// you have two rules here, you can see the rules point at the targets below
	"test_room_price_${var.env_level}" = {
	  description         = "Trigger test room price cron"
	  schedule_expression = "cron(20 4 * * ? *)"
	  enabled             = true
	  event_pattern       = null
	}
	"test_room_details_${var.env_level}" = {
	  description         = "Trigger test room details cron"
	  schedule_expression = "cron(50 3 * * ? *)"
	  enabled             = true
	  event_pattern       = null
	}
  }

  targets = {
	// you have two targets here, you can see the targets point at the api_destinations below
	"test_room_price_${var.env_level}" = [
	  {
		name            = "send-request-to-test-room-price-${var.env_level}"
		destination     = "test_room_price_${var.env_level}"
		attach_role_arn = true
	  }
	]
	"test_room_details_${var.env_level}" = [
	  {
		name            = "send-request-to-test-room-details-${var.env_level}"
		destination     = "test_room_details_${var.env_level}"
		attach_role_arn = true
	  }
	]
  }

  connections = {
	"test_room_price_${var.env_level}"   = local.connection
	"test_room_details_${var.env_level}" = local.connection
  }

  api_destinations = {
	// you need two destinations here, so we add two destinations
	"test_room_price_${var.env_level}" = {
	  description                      = "my test room price endpoint"
	  invocation_endpoint              = "https://example.com/generate_cts/*"
	  http_method                      = "POST"
	  invocation_rate_limit_per_second = 10
	},
	"test_room_details_${var.env_level}" = {
	  description                      = "XXX"
	  invocation_endpoint              = "https://example.com/generate_cts/*"
	  http_method                      = "POST"
	  invocation_rate_limit_per_second = 10
	}
  }
}

The solution should be scalable.

I really appreciate your effort, sir. Thanks a lot 👍
