Render Payment Modal

The SDK provides two easy methods of making collections via the famous payment modal. Learn more
  1. Flutterwave Inline
  2. Flutterwave Standard

​
Get Started

Edit the paymentForm.php and processPayment.php files to suit your purpose. Both files are well documented. Simply redirect to the paymentForm.php file on your browser to process a payment. In this implementation, we are expecting a form encoded POST request to this script. The request will contain the following parameters. 

 {
    "amount": "The amount required to be charged. (*)",
    "currency": "The currency to charge in. (*)",
    "first_name": "The first name of the customer. (*)",
    "last_name" : "The last name of the customer. (*)",
    "email": "The customers email address. (*)",
    "phone_number": "The customer's phone number. (Optional).",
    "success_url": "The url to redirect customer to after successful payment.",
    "failure_url": "The url to redirect customer to after a failed payment.",
    "tx_ref":"The unique transaction identifier. if ommited the apiclient would generate one"
 }
The script in paymentProcess.php handles the request data via the PaymentController. If you are using a Framework like Laravel or CodeIgniter you might want to take a look at the PaymentController 
<?php

declare(strict_types=1);

# if vendor file is not present, notify developer to run composer install.
require __DIR__.'/vendor/autoload.php';

use Flutterwave\Controller\PaymentController;
use Flutterwave\EventHandlers\ModalEventHandler as PaymentHandler;
use Flutterwave\Flutterwave;
use Flutterwave\Library\Modal;

# start a session.
session_start();

try {
    Flutterwave::bootstrap();
    $customHandler = new PaymentHandler();
    $client = new Flutterwave();
    $modalType = Modal::POPUP; // Modal::POPUP or Modal::STANDARD
    $controller = new PaymentController( $client, $customHandler, $modalType );
} catch(\Exception $e ) {
    echo $e->getMessage();
}

if ($_SERVER["REQUEST_METHOD"] === "POST") {
    $request = $_REQUEST;
    $request['redirect_url'] = $_SERVER['HTTP_ORIGIN'] . $_SERVER['REQUEST_URI'];
    try {
        $controller->process( $request );
    } catch(\Exception $e) {
        echo $e->getMessage();
    }
}

$request = $_GET;
# Confirming Payment.
if(isset($request['tx_ref'])) {
    $controller->callback( $request );
} else {
    
}
exit();

​
Configuration settings

Create a .env file and add the bootstrap method first before initiating a charge. 
use \Flutterwave\Flutterwave;

# normal configuration
Flutterwave::bootstrap(); # this will use the default configuration set in .env
if you do not wish to use a .env, you can simply pass your API keys like the example below. 
use \Flutterwave\Helper\Config;

$myConfig = Config::setUp(
    'FLWSECK_TEST-XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX-X',
    'FLWPUBK_TEST-XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX-X',
    'FLWSECK_XXXXXXXXXXXXXXXX',
    'staging'
);
 
Flutterwave::bootstrap($myConfig);

Testing

All of the SDK’s tests are written with PHP’s phpunit module. The tests currently test: Account, Card, Transfer, Preauth, Collection Subaccount, Payout Subaccount, Subscriptions and Paymentplan They can be run like so: 
phpunit
NOTE: If the test fails for creating a subaccount, just change the account_number account_bank and businesss_email to something different
NOTE: The test may fail for account validation - Pending OTP validation depending on whether the service is down or not
