orchestrator-pp-flow

orchestrator-pp-flow is a TypeScript library that helps you build your own payment page.

It provides a flow object with all the necessary methods, data, and events required to initialize and complete a payment process.

📦 Installation

npm install orchestrator-pp-flow

Requires Node.js v24+

⚡️ Quick Start

1. Create a flow instance

To get started, create a flow instance by passing the API host and a payment method factory (implementing PaymentMethodFactory from orchestrator-pp-core):

import PPFlow from 'orchestrator-pp-flow';
import paymentMethodFactory from '...';

const apiHost = 'https://example.com';
const flow = PPFlow(apiHost, paymentMethodFactory);

2. Subscribe to events

You can subscribe to events at any point, but if you want to catch events emitted during initialization, subscribe before calling init:

flow.on('init', (context) => {
  console.log(context);
});

A full list of events and their handler parameters is defined in the exported EventMap type.

3. Initialize the flow

Call the init method with a JWT token to load the payment context and project settings:

const jwtToken = '...';
await flow.init(jwtToken);

Or use event-based initialization:

flow.init(jwtToken);

flow.on('init', (context) => {
  console.log(context);
});

4. Use payment context

After initialization, you can access payment data via the flow context:

console.log(flow.context.getAmount());

Or from the event handler:

flow.on('init', (context) => {
  console.log(context.getAmount());
});

Note: the context is only populated after calling flow.init. Accessing it before will return empty or default values (e.g., amount = 0).

A full description of context properties is available in the exported Context interface.
