THE PRODUCT

What Is GPCB Pay?

GPCB Pay stands for General PayPal Card Bridge. It is a commercial integration designed to help WooCommerce merchants connect supported PayPal card payment experiences to their stores.

The product combines a lightweight WooCommerce Connector with a private SaaS service responsible for trusted payment coordination.

GPCB Pay does not replace WooCommerce, operate as an independent payment processor, or take over the merchant's PayPal account.

One integration. Clear responsibilities.

The merchant retains control of the WooCommerce store and uses their own eligible PayPal Business account.

OUR PURPOSE

Why We Built GPCB Pay.

Payment integration is about more than displaying a payment option at checkout.

A customer may approve a payment while a network interruption prevents the store from receiving the final response. Repeated requests can also introduce uncertainty unless the original payment attempt is tracked carefully.

GPCB Pay was built around the idea that payment completion should be supported by verified evidence, not assumptions.

By separating WooCommerce commercial authority from server-side PayPal payment coordination, the integration aims to make these boundaries explicit and easier to maintain.

THREE DISTINCT RESPONSIBILITIES

How GPCB Pay Works

The integration is built around explicit boundaries between the store, the SaaS service, and the payment provider.

01 STORE COMMERCE

WooCommerce

Maintains the commercial order, checkout context, products, totals, currency, and final order payment state.

02 TRUSTED PAYMENT OPERATIONS

GPCB Pay SaaS

Coordinates authenticated payment requests, PayPal order creation, verified capture, idempotency, and supported recovery.

03 PAYMENT PROVIDER

PayPal

Provides the applicable payment services and hosted card-entry experiences according to merchant eligibility and provider requirements.

The browser is not the final payment authority.

PayPal approval alone does not authorize WooCommerce to mark an order paid. Payment completion depends on trusted server-side capture verification.

HOW WE THINK

Our Engineering Principles

These principles guide the design of GPCB Pay's payment integration and its handling of uncertain payment outcomes.

Verify Before Success

A browser message or payment approval is not proof of completed payment. WooCommerce completion requires trusted, verified capture evidence.

Respect System Authority

WooCommerce owns the commercial order. GPCB Pay coordinates trusted payment operations. PayPal remains the payment provider.

Protect Credentials

Sensitive merchant credentials belong within protected server-side workflows, not public browser code or customer-facing pages.

Prevent Duplicate Captures

Durable request identities and idempotency safeguards help prevent unnecessary repeated payment capture operations.

Maintain Durable State

Payment attempts are tracked using persisted state so supported interruptions can be evaluated against the original payment identity.

Fail Closed When Uncertain

When sufficient trusted payment evidence is unavailable, the system must not declare an order paid based on assumptions.

TRANSPARENCY MATTERS

Clear About What We Do. And What We Don't.

Merchants should understand what the integration provides, what it depends on, and where its responsibilities end.

01 / INDEPENDENCE

Independent Product

GPCB Pay is independently developed. It is not an official PayPal or WooCommerce product and is not endorsed by either.

PayPal and WooCommerce remain separate products with their own requirements, terms, and responsibilities.

02 / PAYMENT PROVIDER

Not a Payment Processor

GPCB Pay does not independently process card transactions or act as a merchant of record. Supported payments use the merchant's own PayPal Business relationship.

Applicable PayPal processing fees are separate from GPCB Pay SaaS charges.

03 / ELIGIBILITY

Payment Availability Varies

Guest Card availability depends on PayPal requirements, the merchant account, and the checkout context.

Advanced Card Payments require specific PayPal merchant eligibility and approval. They are not available universally.

04 / SERVICE DEPENDENCIES

External SaaS Connection

The WooCommerce Connector communicates with the private GPCB Pay SaaS Payment Core.

The Connector is separate from paid SaaS access. Service interruptions may affect payment availability, and recovery cannot be guaranteed in every case.

Customer card-data boundaries

Supported card-entry experiences use PayPal-hosted payment interfaces. The Connector and GPCB Pay SaaS are not designed to collect or store buyers' complete card numbers or CVV.
