Why G8

Fast. Secure. Reliable.

Payments are only as good as the infrastructure behind them. G8 is built around the three things that matter most at checkout.

Speed

Go live faster and keep checkout fast as you grow.

  • One integration instead of many
  • Real-time routing decisions
  • Hosted checkout ready from day one

Security

Card data is protected at every step of the payment flow.

  • Tokenization of card data
  • 3-D Secure and fraud screening
  • Encryption, access control, audit trails

Reliability

Payments keep flowing even when a provider has issues.

  • Automatic failover between acquirers
  • Smart cascading on soft declines
  • Continuous transaction monitoring

One infrastructure layer

Turn declines into approved revenue.

G8 connects your checkout to every acquirer you work with and sends each transaction down the path most likely to be approved.

01

Payment gateway

Accept card payments through one API, hosted checkout or payment links. Card data is tokenized, and with hosted checkout it never touches your servers.

02

Payment orchestration

Route by card brand, country, currency, amount or MID. Cascade soft declines and fail over automatically when a connection degrades.

03

MID onboarding

Get the right merchant account structure for your payment model. We match you with acquiring partners and help get your MIDs live.

04

Transaction processing

Authorizations, captures, refunds and recurring flows — with statuses and history across all your MIDs in one view.

05

Anti-fraud & ML prediction

Explainable ML models score every transaction in real time — predicting approval likelihood, blocking fraud before authorization and deciding when to retry and where to route.

06

Alerting services

Bring RDR and Ethoca alerts into structured dispute workflows and act on signals before they become chargebacks.

Orchestration

Routing, cascading and failover.

Route transactions across acquiring connections, retry soft declines on the next best route and switch automatically when a provider goes down — keeping approvals resilient when conditions change.

  • Rule-based routing across acquiring connections
  • Intelligent cascading on soft declines
  • Automatic failover when a connection degrades

How it works

From first call to live traffic.

  1. Integrate

    Connect once to the G8 API, or use hosted checkout to keep card data off your servers.

  2. Onboard

    We help you open MIDs with acquiring partners that fit your business model and markets.

  3. Configure

    Set routing, cascading and failover rules across all your MIDs — without redeploying.

  4. Scale

    Track performance, add acquirers and adjust routing as volumes and markets grow.
