Package Exports

@bleumi/pay-sdk

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@bleumi/pay-sdk) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Bleumi Pay SDK for NodeJS

The Bleumi Pay SDK is a one-stop shop to help you integrate ERC-20, Ethereum, xDai payments and/or payouts into your business or application. The SDK bundles Bleumi Pay API into one SDK to ease implementation and support.

bleumi-pay-sdk-nodejs is a TypeScrpit-NodeJS library that provides an interface between your NodeJS application and Bleumi Pay API. This tutorial covers the basics, including examples, needed to use the SDK.

Getting Started

The Bleumi Pay SDK for NodeJS bundles TypeScript definition files for use in TypeScript projects and to support tools that can read .d.ts files. Our goal is to keep these TypeScript definition files updated with each release for any public api.

Pre-requisites

Before you can begin using these TypeScript definitions with your project, you need to make sure your project meets a few of these requirements:

Development Environment

Use TypeScript v2.x
Includes the TypeScript definitions for node. You can use npm to install this by typing the following into a terminal window:
```
npm install --save-dev @types/node
```
If you are targeting at es5 or older ECMA standards, your tsconfig.json has to include 'es5' and 'es2015.promise' under compilerOptions.lib. See tsconfig.json for an example.

Obtain An API Key

Bleumi Pay SDK uses API keys to authenticate requests. You can obtain an API key through the Bleumi Pay Dashboard.

Install Package

In Node.js

npm install @bleumi/pay-sdk -g

Run Sample Code

The following code generates a payment request to accept payment from the buyer:

import { PaymentsApi, PaymentsApiApiKeys, CreatePaymentRequest, EthAddress, Chain } from '@bleumi/pay-sdk';

// Instantiate client
const bleumiPay = new PaymentsApi();

async function createPayment(id: string) {
    try {
        bleumiPay.setApiKey(PaymentsApiApiKeys.ApiKeyAuth, '<YOUR_API_KEY>'); //Replace <YOUR_API_KEY> with your actual API key
        const buyer = new EthAddress('<BUYER_ADDR>'); // Replace <BUYER_ADDR> with the Buyer's Enthereum Network Address
        const merchant = new EthAddress('<MERCHANT_ADDR>'); // Replace <MERCHANT_ADDR> with the Merchant's Enthereum Network Address

        const createPaymentRequest = new CreatePaymentRequest();
        createPaymentRequest.id = id;
        createPaymentRequest.buyerAddress = buyer;
        createPaymentRequest.transferAddress = merchant;

        const chain = Chain.Ropsten; // Specify the chain for payment creation
        const response = await bleumiPay.createPayment(createPaymentRequest, chain);
        const createPaymentResponse = response.body;
        console.log(JSON.stringify(createPaymentResponse));
    } catch (err) {
        console.error('Error statusCode:', err.response.statusCode);
        console.error('Error reponse:', err.response.body);
    }
}
