Node

Node to access the PaySwitcher API

In this section, we will cover the steps to do an easy integration of your Node Backend server

Using Node SDK for app server is OPTIONAL. You can use our REST APIs for the

Requirements

Node 12 or higher.

Installation

Install the package with:

npm install @payswitcher/payswitcher-node --save
# or
yarn add @payswitcher/payswitcher-node

Usage

The package needs to be configured with your account's secret key, which is available in the PaySwitcher Dashboard. Require it with the key's value:

const payswitcher = require('payswitcher')('snd_efe...');

payswitcher.paymentIntents.create(
  {
    // Refer the request body of payments from this API https://app.swaggerhub.com/apis-docs/bernard-eugine/PaySwitcherAPI/0.0.1#/Payments/Create%20a%20Payment

    currency: "USD",
    capture_method: "automatic",
    amount_to_capture: 10000,
    customer_id: "payswitcherCustomer",
    email: "[e-mail]",
    name: "John Doe",
    phone: "999999999",
    phone_country_code: "+65",
    description: "Its my first payment request",
    authentication_type: "no_three_ds",
    return_url: "https://app.payswitcher.com",

        zip: "94122",
        country: "US",
        first_name: "John",
        last_name: "Doe"
      },
      phone: {
        number: "123456789",
        country_code: "+1"
      }
    },
    billing: {
      address: {
        line1: "1467",
        line2: "Harrison Street",
        line3: "Harrison Street",
        city: "San Fransico",
        state: "California",
        zip: "94122",
        country: "US",
        first_name: "John",
        last_name: "Doe"
      },
      phone: {
        number: "123456789",

      order_details: {
        product_name: "Apple iphone 15",
        quantity: 1
      },
    }
  }
)
  .then(customer => console.log(customer.id))
  .catch(error => console.error(error));

If you are using ES modules and async/await,

import PaySwitcher from 'payswitcher';
const payswitcher = new PaySwitcher('snd_efe...');

const payments_response = await payswitcher.paymentIntents.create(
  {
    // Refer the request body of payments from this API https://app.swaggerhub.com/apis-docs/bernard-eugine/PaySwitcherAPI/0.0.1#/Payments/Create%20a%20Payment

    email: "[e-mail]",
    name: "John Doe",
    phone: "999999999",
    phone_country_code: "+65",

Refunds	Create a refund Retrieve a refund
Customers	Create a customer Retrieve a customer Delete a customer
Payment Methods	Create a payment method List customer's payment methods List merchant's payment methods

The request body(req.body) for all API's below can be referred from API reference

const express = require("express");
const app = express();
// This is a public sample test API key.
// Don't submit any personally identifiable information in requests made with this key.
// Sign in to see your own test API key embedded in code samples.

const payswitcher = require('@payswitcher/payswitcher-node')('snd_b8df3xxx......');
