Google Cloud introduced the Billing Budget API , making it possible to manage cost guardrails programmatically instead of through the console.

Terraform Example

Terraform gained beta support alongside the API release:

data "google_billing_account" "account" {
  provider        = google-beta
  billing_account = "000000-0000000-0000000-000000"
}

resource "google_billing_budget" "budget" {
  provider        = google-beta
  billing_account = data.google_billing_account.account.id
  display_name    = "Example Billing Budget"

  amount {
    specified_amount {
      currency_code = "USD"
      units         = "100000"
    }
  }

  threshold_rules {
    threshold_percent = 0.5
  }
}

Why It Matters

  • Enforce budgets as code across environments.
  • Trigger automated notifications or shutdown workflows when thresholds are breached.
  • Eliminate manual console steps during project onboarding.

Next Steps

  • Combine the API with Pub/Sub budget alerts for automated remediation.
  • Version-control budget definitions and review them like any other infrastructure change.
  • Monitor GA announcements; beta APIs may change and require updates to Terraform providers.
