Installation

You can use the PHP client by installing the Composer package and adding it to your application’s dependencies:

composer require devscast/flexpay

Usage

Authentication

• Step 1. Contact Flexpay to get a Merchant Account You will receive a Merchant Form to complete in order to provide your business details and preferred Cash out Wallet or Banking Details.
• Step 2. Once the paperwork is completed, you will be issued with Live and Sandbox Accounts (Merchant Code and Authorization token)

Then use these credentials to authenticate your client

use Devscast\Flexpay\Client as Flexpay;
use Devscast\Flexpay\Credential;
use Devscast\Flexpay\Environment;

$flexpay = new Flexpay(
    new Credential('token', 'merchant_code'),
    Environment::SANDBOX // use Environment::LIVE for production
);

Create a Payment Request

use Devscast\Flexpay\Data\Currency;
use Devscast\Flexpay\Request\CardRequest;
use Devscast\Flexpay\Request\MobileRequest;

$mobile = new MobileRequest(
    amount: 10, // 10 USD
    currency: Currency::USD,
    phone: "243999999999",
    reference: "your_unique_transaction_reference",
    description: "your_transaction_description",
    callbackUrl: "your_website_webhook_url",
);

$card = new CardRequest(
    amount: 10, // 10 USD
    currency: Currency::USD,
    reference: "your_unique_transaction_reference",
    description: "your_transaction_description",
    callbackUrl: "your_website_webhook_url",
    homeUrl: "your_website_home_url",
)

Note: we highly recommend your callbacks urls to be unique for each transaction.

Mobile Payment

Once called, Flexpay will send a payment request to the user's mobile money account, and the user will have to confirm the payment on their phone. after that the payment will be processed and the callback url will be called with the transaction details.

$response = $flexpay->pay($mobile);

Visa Card Payment

You can set up card payment via VPOS features, which is typically used for online payments. it's a gateway that allows you to accept payments from your customers using their credit cards.

$response = $flexpay->pay($card);
// redirect to $response->url to complete the payment

handling callback (callbackUrl, approveUrl, cancelUrl, declineUrl)

Flexpay will send a POST request to the defined callbackUrl and the response will contain the transaction details. you can use the following code to handle the callback by providing incoming data as array.

$state = $flexpay->handleCallback($_POST);
$state->isSuccessful(); // true or false

Check Transaction state

You don't trust webhook ? you can always check the transaction state by providing the order number.

$state = $flexpay->check($payment->orderNumber);
$state->isSuccessful(); // true or false
