Pre-launch checklist (18 items)

TLDR: before enabling checkout in production, tick the 18 items below. The checklist follows a logical order: account → branding → payments → store integration → marketing → smoke test → launch.

Account & domain

• 1. Email verified — you must click the email link before starting onboarding. Verification confirms that password resets, notifications and operational messages actually reach the merchant.
• 2. Strong password saved in a password manager (1Password, Bitwarden).
• 3. Checkout slug verified — the {yourslug}.wooshpayment.com subdomain is generated at signup. If you regenerate it from Dashboard → Settings, do it before launch and re-check Apple Pay/custom domain.
• 4. (Optional) Custom domain mapped — checkout.yourstore.com with fixed checkout. prefix. Available to all merchants without plan gating. See Custom domain.

Branding & checkout

• 5. Logo URL configured — Dashboard → Checkout → Appearance. Use a public HTTPS link to PNG/SVG/JPG; if you do not have a logo yet, leave the store name.
• 6. Checkout colors verified — brand color + secondary color in hex format (e.g. #FF6B35) with readable contrast on the button.
• 7. Checkout language set — leave "Auto" to detect the customer language, or force one language from the Checkout page.
• 8. Trust badges, banner and reviews checked — enable only real content. Phone stays required and should not be disabled.

Payments

• 9. Payment method active — connect Whop with Administrator/Owner role, Product ID and webhook secret if you want cards and wallets; or enable Cash on Delivery if you are launching COD-only. See Whop setup.
• 10. Apple Pay verified — only if you use Whop/wallets: check in the Whop dashboard that the {slug}.wooshpayment.com domain (or checkout.yourstore.com if active) is among the registered domains. See Apple Pay setup.
• 11. (Optional) Cash on Delivery (COD) active — useful in IT/ES/RO/PL. See Cash on Delivery.

Store integration

• 12. Shopify/WooCommerce connected — see Shopify integration or WooCommerce integration.
• 13. Checkout interceptor verified — on Shopify the ScriptTag is installed at the OAuth callback, but it must be validated from the real cart on the live theme; on WooCommerce the official plugin must be active. Open your store, click "Checkout / Proceed to checkout" and verify that it redirects to your WooshPayment subdomain. If Shopify does not redirect, do not send traffic: see Script tag debug or request support/app embed validation; if Woo does not redirect, check Settings → WooshPayment in WordPress.
• 14. Shipping configured both in WooshPayment and in the Shopify/Woo panel. Without rates the checkout shows "No method available".
• 15. Taxes/VAT verified in your store backend for your country.

Marketing & analytics

• 16. Pixel/CAPI active if you use them — GA4, GTM, Meta Pixel, TikTok. See Marketing pixels. Test the Purchase event with a pilot order.

Final smoke test

• 17. Real pilot order — for Whop use €0.50 or the minimum allowed amount, for COD use a clearly recognizable internal order. Buy from your store and verify:
  • Order created in Shopify/Woo with status paid for Whop or pending/unpaid for COD
  • Session marked COMPLETED in WooshPayment → Orders
  • Merchant notification received (also check Spam the first time)
  • Server-side pixel/CAPI events fired (Meta Events Manager, TikTok Events, GA4 DebugView)
• 18. Real iPhone mobile test (not simulator). If you use Apple Pay, verify it opens; in every case iCloud autofill works and no field is hidden by the keyboard. 70% of checkout traffic is mobile.

After launch

1. Dashboard → Orders every day for the first week
2. Dashboard → Integrations → verify Whop stays "Ready" (API key, Product ID, webhook secret), WooCommerce is connected and the latest checkout was intercepted; for Shopify verify Dashboard → Settings and Script tag debug
3. Refund: for now refunds are issued from the Whop dashboard. See Refund flow for the correct procedure that keeps state in sync.

Happy launch.
