Which payment gateways does CARDZ3N integrate with?

CARDZ3N supports native integrations with NMI, Fluidpay, Authorize.net, USAePay, and Valor PayTech, along with APIs for major eCommerce platforms, subscription billing tools, and B2B invoicing, ERP, and CRM systems.

Is my customers' card data stored on my servers?

No. CARDZ3N's gateway integrations use tokenization, so raw card numbers are vaulted by the gateway rather than stored on your servers — reducing your PCI DSS scope and liability.

Choosing the Right Payment Gateway for Your Store

Jedes eCommerce-Unternehmen arbeitet mit einem Payment-Gateway, unabhängig davon, ob diese Wahl für Kunden sichtbar ist. CARDZ3N entwickelt native Integrationen mit NMI, Fluidpay, Authorize.net, USAePay und Valor PayTech, sodass Händler ihren bestehenden Onlineshop, Checkout-Ablauf und ihre Reporting-Tools behalten können und gleichzeitig ein Underwriting erhalten, das sowohl für Hochrisiko- als auch für Standard-eCommerce ausgelegt ist.

⇄

Payment gateway integration: the technical and underwriting work of connecting a storefront's checkout to a processing gateway — API credentials, tokenization, webhook configuration, and fraud rules — so that authorized transactions settle reliably into the merchant's account.

Security, Tokenization & PCI Compliance

CARDZ3N's gateway integrations tokenize and vault customer payment credentials at the point of capture, so raw card numbers are never stored on a merchant's own servers. That reduces PCI DSS scope, supports safer recurring billing and subscription management, and keeps repeat purchases fast without re-collecting card data on every order.

eCommerce Platform Integrations

Whether a store runs on Shopify, WooCommerce, Magento, or a custom cart, CARDZ3N configures the right gateway integration for that platform and the merchant's risk profile. Native APIs and webhooks route checkout events cleanly from the storefront through authorization, capture, and settlement, so nothing has to be stitched together manually.

What a Gateway Integration Actually Involves

A typical integration starts with provisioning API credentials on the chosen gateway, then configuring tokenization so card data is vaulted rather than stored locally. From there, CARDZ3N's team wires up webhooks for real time transaction status, sets fraud and risk rules appropriate to the vertical, runs test transactions end to end, and confirms reporting and payout settings before flipping the integration live.

A payment gateway integration should be invisible to your customers at checkout and completely visible to you in the dashboard — every transaction traceable from click to settlement.

Funding, Reserves & Chargebacks

Most CARDZ3N merchants receive next day deposits, while high risk eCommerce accounts typically receive funds within two business days of settlement. Some accounts use rolling reserves to manage exposure while processing history builds, and CARDZ3N explains those terms up front rather than after approval. Integrated chargeback alerts and dispute tools sit inside the same dashboard as gateway reporting, so disputes get caught and answered quickly.
