This page describes what Pillar8 changes and what it does not.

​
What Pillar8 Changes

Pillar8 changes checkout decisioning by introducing a real-time decision layer that evaluates each session independently and returns a decision package to influence shopper behavior.

​
What Pillar8 Does Not Change

Not Changed

  • PSP integrations
  • Orchestration layers
  • Payment routing
  • Payment processing

​
Data Scope

Pillar8 uses checkout-level context including:
  • Device type
  • Country and currency
  • Cart value
  • Available payment methods
  • Transaction outcome
The optimize API does not require cardholder data.

​
Platform Constraints

Execution depends on checkout environment capabilities. Supported in all environments:
  • Advisory UI
  • Highlighting
  • Merchant-controlled execution
Additional capabilities: Some environments may support deeper control over payment method ordering and presentation.

​
Compliance and Data Handling

Pillar8 operates outside payment processing and does not require access to sensitive payment credentials.
No cardholder data (PAN, CVV) required for decisioning
No payment credentials stored or processed by Pillar8
Outside PCI scope — decisioning layer operates independently
Standard data protection practices supported
Pillar8 processes only checkout-level and transactional metadata needed for optimization. Merchants retain full control of payment processing and compliance obligations.

​
Risk Profile

Pillar8 is designed to be lightweight and low-risk:
  • Minimal integration effort
  • No changes to payment infrastructure
  • No processor replacement dependency
  • No PCI scope expansion for decisioning
