FlexPay Payment Platform

The FlexPay Payment Platform is a simple way to enable your users who may not otherwise qualify for financing to securely finance their order through our easy Lease to Own experience.
Version 1 of the Payment Method is deprecated and will be shut off July 2020. If you're still on V1, please contact our integration team for assistance on migrating to V3. 
How do you know if you're on V1?
Check the domain you're directed to at check, if it's sdk.flexshopper.com, you're on V1.

Preview the experience
Add the Payment Button to your store
<script src="https://pp3.flexshopper.com/sdk/js?authKey=AUTH_KEY"></script>
<script>
FlexSDK.Button({
    createOrder: function() {}
    onSign: function() {}
}).render('#elementSelector');
</script>
Make sure to replace AUTH_KEY with your organization's assigned authorization key.  
Creating a transaction 
To create a lease, the createOrder method must be implemented.  It will be called when the customer clicks on the FlexPay Payments button; once called, createOrder:
Makes use of actions.transaction.create() to create a valid order.  A complete list of options can be found here.
Launches the FlexShopper Payment modal where the customer may apply, get a spending limit, and sign the lease for their cart.  Upon receiving a spending limit, customers are also given the chance to return to the store and add more items to their cart.
FlexSDK.Button({
    createOrder: function(data, actions) {
        return actions.transaction.create({
                cost: 120.34,
                transactionId: "ABC-129384",
                items: [
                    {
                        description: "Macbook Pro 13",
                        sku: "ABC123",
                        cost: 120.34,
                        brand: "Apple",
                        condition: "new",
                        quantity: 1,
                    }
                ]
            });
    }
}).render('#elementSelector');
Finalize the transaction
Once the consumer has signed their lease, the onSign method will be called.  In this method you are required to:
Retrieve the order from FlexShopper's system and validate the signed agreement.
Finalize the order, confirming the lease's total value and items, as well as confirming that the shipping process is underway.
If these steps are not followed, orders may not be fulfilled or billed correctly.  You will have to implement an endpoint that your customers can interact with that consumes our Backend API:
On the client:
FlexSDK.Button({
    onSign: function(data) {
        return fetch('/validate-order', {
            method: 'POST',
            body: JSON.stringify(data)
        })
    }
}).render('#elementSelector');
The data object will have the following shape:
{
    "leaseNumber": "1234567",
    "transactionId": "ABC-129384"
}
On the server:
node.js
PHP
Python
const axios = require('axios');
// helper method holding business logic to validate order
const checkOrder = require('utils/check-order.js');
​
const flexShopperClient = axios.create({
 baseURL: 'https://apis.sandbox.flexshopper.com/v3',
 headers: {
  Authorization: 'YOUR_API_KEY'
 }
});
​
 export const validateOrderHandler = async (req, res) => {
  const transactionId = req.body.transactionId;
  const transaction = await flexShopperClient.get(`/transactions/${transactionId}`)
  const orderStatus = await checkOrder(transaction)
  
  if (!orderStatus.isValid) {
   res.json({valid: false, errors: orderStatus.errors});
   return res.send(400);
  }
  
  await flexShopperClient.post(`/transactions/${transactionId}/finalize`)
  
  res.json({valid: true});
  res.send(200);
 }; 
use GuzzleHttp\Client;
use Psr\Http\Message\ServerRequestInterface;
use Psr\Http\Message\ResponseInterface;
use Zend\Diactoros\Response\JsonResponse;
​
$app->post('/validate-order', function (ServerRequestInterface $request): ResponseInterface {
    $flexShopperClient = new Client([
        'base_uri' => 'https://apis.sandbox.flexshopper.com/v3',
        'headers' => [
            'Authorization' => 'YOUR_API_KEY'
        ]
    ]);
​
    $transactionId = $request->getParsedBody()['transactionId'];
    $transaction = json_decode($flexShopperClient->get("/transactions/${transactionId}")->getBody());
    $orderStatus = $checkOrder($transaction);
​
    if (!$orderStatus->isValid) {
        return new JsonResponse(['valid' => false, 'errors' => $orderStatus->errors], 400);
    }
    
    $flexShopperClient->post("/transactions/${transactionId}/finalize");
​
    return new JsonResponse(['valid' => true, 'parsed_body' => $transactionId]);
});
​
​
from flask import Flask
from flask import jsonify
from flask import request
from requests_toolbelt import sessions
​
app = Flask(__name__)
​
​
flexshopper_client = sessions.BaseUrlSession(base_url='https://apis.sandbox.flexshopper.com/v3')
flexshopper_client.headers.update({'Authorization': 'YOUR_API_KEY'})

def validate_order():
    data = request.get_json()
    transaction_id = data['transactionId']
    transaction = flexshopper_client.get('/transaction/%s' % transaction_id)
    order_status = check_order(transaction)
​
    if not order_status['valid']:
        return jsonify({'valid': False, 'errors': order_status['errors']}), 400, {'ContentType': 'application/json'}
​
    flexshopper_client.post('/transaction/%s/finalize' % transaction_id)
    return jsonify({'valid': True}), 200
​
Make sure to replace API_KEY with your organization's assigned API key.  Note that API keys and authorization keys are separate.

After the order has been placed
Once FlexShopper receives confirmation that the consumer has received their item (delivery confirmation), your organization will be paid for the value of the lease.  Use the Confirm Shipment API endpoint to inform FlexShopper of the shipment's status: 
Confirm Shipment
/api-reference/purchase-transactions/confirm-shipment
Congratulations!
Once you've confirmed shipment, you're done.  That's all there is to it!
