LumePay SDK
A JavaScript SDK for interacting with the LumePay payment gateway API.

Installation
npm install lumepay-sdk

Usage
To use the LumePay SDK, you need to create an instance of the PaymentGateway class. Here's an example:

You can then use the gateway object to create a payment intent, retrieve a payment intent by ID, or submit a payment.

Creating a Payment Intent
const intent = await gateway.createIntent({ amount: 1000, customerEmail: 'customer@example.com', metadata: { /* optional metadata */ } });

Retrieving a Payment Intent
