​
Shopify Integration

Pillar8 integrates with Shopify through a checkout UI extension and backend webhook flow.

​
Current Integration Model

The current Shopify implementation uses:
  • A checkout block extension
  • The Pillar8 optimize API
  • Webhook-based learning from transaction outcomes

​
How It Works in Shopify

1

Checkout context is captured

The extension reads checkout token, cart value, country and currency, available and presented payment methods, and device context.
2

Pillar8 returns a decision package

The extension sends checkout context to the Pillar8 optimize API and receives a decision package in response.
3

Advisory layer is rendered

Pillar8 influences buyer behavior through an advisory block in checkout. This advisory layer recommends a payment method when confidence and visibility conditions are met.

​
Current Shopify Constraint

The active Shopify implementation does not directly reorder Shopify’s payment method list. It currently operates as an advisory decision layer.

​
What Shopify Integration Is Good For

  • Validating decision quality
  • Guiding shopper behavior
  • Measuring completion impact
  • Learning from real transaction outcomes

​
Integration Components

Checkout UI extension

Renders advisory layer in checkout.

Optimize API

Returns decision packages based on context.

Order-completion webhook

Captures transaction outcomes.

Advisory rendered telemetry

Tracks advisory visibility and impact.

​
Shopify Webhooks Used

The Shopify integration uses multiple webhook events to reconstruct the full transaction lifecycle and improve decision accuracy:
  • orders/paid
  • order_transactions/create
  • tender_transactions/create
  • checkouts/create
Shopify is one supported environment. Other environments with deeper checkout control may allow broader execution of the decision package.
