# BNPL integration for Markets

One of the use cases of serviceX is BNPL Gateway.

This page is for Markets to integrate the BNPL Gateway.

If you have not set up a Market yet, please refer to Integration guide.

# Flow

create order

After users have finished the BNPL transaction, you will receive a webhook event regarding the order status. You will just need to process the order status on your system.

Once you have finished setting up a Market, what you need to do is

Create an order for BNPL
Handle webhook events

# Create an order

Every BNPL transaction should be associated with an order. You need to generate a new order object on your backend. You will obtain order ID, so you can check the order status afterwards.

WARNING

Please ensure you keep Order ID in your system because it is necessary when the transaction is completed.

# Implementation with SDK

Node.js
Java
.NET

const { Credify } = require("@credify/nodejs");

// You obtain these on the serviceX dashboard.
const signingPrivateKey = `-----BEGIN PRIVATE KEY-----
your private key...
-----END PRIVATE KEY-----`;
const apiKey = "YOUR_API_KEY";

const referenceId = req.body.reference_id;
const totalAmount = req.body.total_amount;
const orderLines = req.body.order_lines;
const paymentRecipient = req.body.payment_recipient;
// This is a sample. It should use `async`
const credify = await Credify.create(signingPrivateKey, apiKey, { mode: "sandbox" });
// This is a sample. It should use `async`
const data = await credify.bnpl.createOrder(
  referenceId,
  totalAmount,
  orderLines,
  paymentRecipient
);

# Handle webhook events

Once BNPL transaction is completed, you will receive a webhook event from Credify, so you can update the purchase status to completed. This webhook event has Authorization header to prove it is coming from the Credify server. You can verify the access token with Token Introspection API or SDK.

This webhook event contains BNPL order ID that you are supposed to keep in your cache or storage.
