Sandbox

Test mode loads the real checkout embed against your test plan, so the full flow — embed UI, declines, webhook → order.status = paid — runs end-to-end with no real charges. Toggle with WHOP_SANDBOX=true and NEXT_PUBLIC_WHOP_SANDBOX=true.

Any future expiry / 3-digit CVC works. These cards are accepted by the embed when test credentials are loaded.

End-to-end test flow

Add a product to your cart, fill in customer details and submit. You'll land on /pay/<publicId>.
The embed renders the test-mode checkout UI.
Choose a test card, hit Pay. The provider's test webhook fires /api/whop/webhook and the order flips to paid.
The page refreshes and shows the “Paid in full” receipt.

      "personalization": { "monogram": "T.C.", "thread": "Ivory" }
    }]
  }'

The response's payUrl is a live link on this site — open it, pay with a test card, and the order flips to paid.
