WooCommerce Checkout Launch Checklist for Peptide Merchants

Confirm your checkout type and approved integration

Identify whether your store uses WooCommerce’s Checkout block or classic checkout. Confirm that the exact gateway extension supports that checkout and your WooCommerce version. An extension that does not support block checkout can fail to appear even when enabled. Confirm your merchant approval covers the domain and catalog before connecting production credentials.

Configure staging with test-mode credentials

Install the approved extension and follow its provider documentation to configure the test account and callback settings. Keep test credentials separate from production. Disable live fulfillment, marketing messages, and integrations that would treat a test order as real. WooCommerce test orders can otherwise trigger order emails or appear in analytics.

Verify each transaction against its order

• Place guest and signed-in test orders on desktop and mobile.
• Run approval, decline, and cancellation paths and compare the order notes with the gateway status.
• Check tax and shipping totals, order emails, stock changes, and the refund workflow.

Repeat the checkout checks at launch

Confirm the new payment method appears to shoppers under the applicable shipping, currency, and order conditions. Verify that the provider transaction ID reaches the order record. Assign a named owner to reconcile the first batch and investigate any mismatch before fulfillment.
