Sandbox Testing

Use environment: "sandbox" for development and automation testing.

Sandbox requests can:

• Validate API keys.
• Create API print-order records.
• Exercise idempotency.
• Exercise billing gates with billing.required.
• Later, import orders into WHCC sandbox validation endpoints.

Sandbox requests must not submit production fulfillment.

Billing-gate test

{
  "environment": "sandbox",
  "billing": {
    "required": true
  }
}

If your account billing is inactive, the API returns 402 billing_required.
