InterPep automatically cascades failed payments across multiple processors — in real time, completely transparently, with no friction for your customer.
InterPep is built for merchants who can't afford to lose revenue to declined transactions — whether from high risk, high volume, or unreliable processors.
Configure a sequence of processors. When one declines, MCPG automatically routes to the next — no code required.
A BridgerPay-inspired overlay shows live routing progress to customers without exposing processor names.
Card data is encrypted with AES-256-CBC, stored in a 5-minute transient, and destroyed the moment the cascade completes.
Seamlessly handles 3DS authentication mid-cascade, then resumes the routing flow after bank verification.
Built as a proper WC_Payment_Gateway extension with full HPOS compatibility and WooCommerce order notes logging.
Supports vSafe (2D & 3D) and EuPaymentz (2D) with an extensible architecture to add more processors easily.
Organized admin interface with General, Processors, and Test Cards tabs. Per-processor sandbox toggles included.
Process refunds directly from the WooCommerce order admin. Per-processor statement descriptors supported.
Your customer sees a seamless checkout. Behind the scenes, MCPG handles everything.
Card details are collected at checkout and immediately encrypted with AES-256-CBC. A 5-minute secure transient is created.
Single form entryThe real-time progress UI displays payment routing status. Customers see numbered routes with live spinners and indicators.
Transparent UXIf the first processor declines, MCPG automatically advances to the next in your configured sequence — invisibly.
Auto-failoverIf 3D Secure verification is triggered, the customer is redirected to their bank, then seamlessly returned to continue the cascade.
3DS compatibleOn success, the order is marked complete, card data is permanently destroyed, and the customer sees confirmation. If all processors fail, the order is held with a clear message.
Data auto-destroyedEvery declined payment is potential revenue walked out the door. With MCPG's automatic cascade, that transaction gets a second (and third) chance through a different processor — automatically, before your customer even notices.
While MCPG silently reroutes a declined payment, your customer watches a clean progress UI — no error message, no panic, no re-entering card details. They see "Payment Route 2 processing" and that's all. The cascade is completely transparent.
Card data is encrypted with AES-256-CBC the moment it's captured and stored in a WordPress transient with a hard 5-minute TTL. The moment the cascade resolves — success or failure — the transient is permanently deleted. Zero card data is ever stored to disk long-term.
