How to authenticate

IntaSend-php supports various IntaSend's payment features. Below are the credentials needed for authentication.

token - Is the API token and is required for status checks, chargeback request, send money, and wallet services. publishable_key - Also know as the public key is required during payment collections/checkout only.

How to pass your credentials

Add your credentials from the .env (recommended) in an array and include it in your requests. Example:

$credentials = [
    'token'=>'<YOUR-SECRET-TOKEN-HERE>',
    'publishable_key'=>'<YOUR-PUBLISHABLE_KEY-HERE>'
];

$checkout = new Checkout();
$checkout->init($credentials);

How to receive payments using Checkout URL

With IntaSend, you can generate a secure checkout page where you redirect your users to complete payments.

Below is a basic example on how to set up. Check full example in your Laravel playground.

use IntaSend\IntaSendPHP\Checkout;
use IntaSend\IntaSendPHP\Customer;

$credentials = [
'publishable_key' =>  env('INTASEND_PUBLISHABLE_KEY'),
'test' =>  env('INTASEND_TEST_ENVIRONMENT', true),
];

$customer = new Customer();
$customer->first_name = "Joe";
$customer->last_name = "Doe";
$customer->email = "[email protected]";
$customer->country = "KE";

$amount = 10;
$currency = "KES";

// Add your website and redirect url where the user will be redirected on success
$host = "https://example.com";
$redirect_url = "https://example.com/callback";
$ref_order_number = "test-order-10";

$checkout = new Checkout();
$checkout->init($credentials);
$resp = $checkout->create($amount = $amount, $currency = $currency, $customer = $customer, $host=$host, $redirect_url = $redirect_url, $api_ref = $ref_order_number, $comment = null, $method = null);

// Redirect the user to the URL to complete payment
print_r($resp->url);

Send M-Pesa STK-Push

Checkout API generates a URL that enables you to do M-Pesa collection and other payment methods. In case you want to leverage only the M-Pesa STK-Push option, you might want to consider this the collection->mpesa_stk_push() option.

use IntaSend\IntaSendPHP\Collection;
$credentials = [
'publishable_key' =>  env('INTASEND_PUBLISHABLE_KEY'),
'test' =>  env('INTASEND_TEST_ENVIRONMENT', true),
];

$collection = new Collection();
$collection->init($credentials);

$response = $collection->create($amount=10, $phone_number="2547...", $currency="KES", $method="MPESA_STK_PUSH", $api_ref="Your API Ref", $name="", $email="[email protected]");
print_r($response);

How to create Payment links

Payment links are free forms that you can share with your customers on email and social media. Unlike Checkout URL, payment links do not required/include customer details when creating them. The customer is expected to put all the details required.

Create a payment link

use IntaSend\IntaSendPHP\PaymentLink;

$credentials = [
    'token'=>'<YOUR-SECRET-TOKEN-HERE>',
    'publishable_key'=>'<YOUR-PUBLISHABLE_KEY-HERE>'
];

$paymentLink = new PaymentLink();
$paymentLink->init($credentials);

$title = "Service 1";
$currency = "KES";
$amount = 100;

# Specify who should take care of the charges. Set to BUSINESS_PAYS for business to handle.

$mobile_tarrif =  "CUSTOMER_PAYS";
$card_tarrif =  "CUSTOMER_PAYS";
$is_active = "true";

$response = $paymentLink->create($title, $currency, $amount, $mobile_tarrif, $card_tarrif, $is_active);
print_r($response);

List or retrive details of payment links by ID

$response = $paymentLink->retrieve()
print_r($response);

$link_id = "AKSL1O1";
$response = $paymentLink->details($link_id);
print_r($response);
