Validate payment flows before launch

CartDNA helps Shopify merchants test payment methods before going live. You can integrate, configure, and validate supported payment gateways in secure test environments using sandbox API credentials provided by our support team.

Most global payment methods support full sandbox testing. Some local payment providers may not provide official test modes. In those situations, CartDNA may provide simulators or controlled live transaction testing to help validate the payment flow safely.

Free Testing Environment for Shopify Merchants

CartDNA payment applications are free to test while supported payment methods offer test or sandbox environments. This allows your team to validate checkout flows, payment authorisations, customer experience, and backend configurations before enabling live customer payments.

Some local payment providers do not offer official test environments. In these cases, CartDNA may provide payment simulators that closely replicate real customer payment journeys. This helps merchants test integrations with minimal operational risk.

Sandbox API Access

Receive test credentials for supported payment methods and begin integration immediately.

Payment Simulators

Use simulated payment flows where official test environments are unavailable.

Guided Setup Support

CartDNA specialists help configure payment applications correctly for your store.

Checkout Validation

Test payment flows, redirects, callbacks, webhooks, and order synchronisation safely.

Live Transactions Require Commercial Approval

Before accepting payments from real customers, merchants must complete CartDNA onboarding requirements. This includes accepting CartDNA terms and entering a valid commercial agreement for the selected payment method and application.

Without an approved commercial agreement, live transaction processing will remain disabled to protect merchants, payment providers, and customers.

Flexible Domain Usage for Shopify Stores

CartDNA payment applications are adaptable for use across multiple public domains connected to the same Shopify store and myshopify subdomain. This provides flexibility for merchants operating regional domains, international storefronts, or market-specific landing pages.

However, live payment instances cannot be shared across multiple Shopify stores. Once a payment application is installed and activated for a specific Shopify store, the payment method configuration cannot be transferred between unrelated stores.
