Payment Integration Package Diagram

Payment integration package diagram

A payment integration package diagram separates the checkout experience from payment orchestration and the external gateway. It also makes the asynchronous webhook path visible, which is important because a payment result may arrive after the original request. A ledger package records the business outcome without exposing its details to the checkout package. Use this diagram in an implementation review to check that provider-specific code stays behind an adapter and that callback handling has an explicit place.

O que há neste desenho

Entenda as decisões por trás dele.

01Separate orchestration

Checkout requests payment without owning gateway details.

02Contain the provider

Keep gateway calls inside an adapter package.

03Handle callbacks

Treat webhooks as a distinct inbound boundary.

04Record outcomes

Update the ledger from verified payment events.

Use to review responsibilities and dependencies before implementing payment flows.

Perguntas frequentes

Dúvidas comuns

Why isolate the gateway adapter?

It keeps provider-specific requests and responses from spreading across the application.

Why show webhooks separately?

They are an inbound asynchronous flow with different verification and retry concerns.

Is this a sequence diagram?

No. It shows module dependencies, not the step-by-step timing of a payment.
