Installation via Composer.

To install the package via Composer, run the following command:

composer require flutterwavedev/flutterwave-v3

Initialization

Create a .env file and follow the format of the .env.example file Save your PUBLIC_KEY, SECRET_KEY, ENV in the .env file

cp .env.example .env

Your .env file should look this. Make sure to retrieve your API keys from your dashboard.

FLW_PUBLIC_KEY=FLWSECK_TEST-XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX-X
FLW_SECRET_KEY=FLWPUBK_TEST-XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX-X
FLW_ENCRYPTION_KEY=FLWSECK_XXXXXXXXXXXXXXXX
FLW_ENV='staging/production'
FLW_LOG_DIR=logs

Render Payment Modal

The SDK provides two easy methods of making collections via the famous payment modal. Learn more

Flutterwave Inline

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);

Payment Plans

Collection Subaccounts

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

Debugging Errors

We understand that you may run into some errors while integrating our library. You can read more about our error messages here.

For authorization and validation error responses, double-check your API keys and request. If you get a server error, kindly engage the team for support.

Support

For additional assistance using this library, contact the developer experience (DX) team via email or on slack.

You can also follow us @FlutterwaveEng and let us know what you think 😊.
