E-commerce integration
X-Cart
A native payment module for X-Cart 4 and X-Cart 5.
An official Superior Payments module for X-Cart's open-source storefront platform. Hosted-field checkout, tokenized customer vault, and Level II/III enrichment for B2B carts — drop-in for X-Cart 5 and supported on the X-Cart 4 LTS branch.
What you get
Hosted-field checkout
Card and ACH inputs render in an iframe served from our vault domain. Storefront PHP, X-Cart core, and your custom modules never see raw PAN — collapsing PCI scope to SAQ A.
Tokenized customer vault
Returning customers see saved payment methods at checkout. Tokens are stored against the X-Cart user profile so one-click checkout works on every return visit.
Subscription billing
Compatible with X-Cart's Recurring Orders module. Tokenized renewals process even after the customer's card is reissued, via account-updater coverage.
B2B / corporate-card optimization
X-Cart B2B cart line-item, customer-code, and tax data is auto-enriched into Level II/III payment fields — qualifying corporate-card transactions for the lowest interchange tiers without manual entry.
