Kopokopo PHP SDK

This is a module to assist php developers in consuming Kopokopo's API

Installation

You can install the PHP SDK via composer.

The recommended way to install the SDK is with Composer.

composer require kopokopo/k2-connect-php

Initialisation

The package should be configured with your client id and client secret which you can get from your account on the kopokopo's app

//Store your client id and client secret as environment variables

//Including the kopokopo sdk
use Kopokopo\SDK\K2;

// do not hard code these values
$options = [
    'clientId' => 'YOUR_CLIENT_ID', 
    'clientSecret' => 'YOUR_CLIENT_SECRET',
    'apiKey' => 'YOUR_API_KEY',
    'baseUrl' => 'https://sandbox.kopokopo.com'
];

$K2 = new K2($options);

After initialization, you can get instances of offered services as follows:

Tokens : $tokens = $K2->TokenService();
Webhooks : $webhooks = $K2->Webhooks();
STK PUSH : $stk = $K2->StkService();
External Recipient : $externalRecipientService = $K2->ExternalRecipientService();
Settlement Transfer : $transfer = $K2->SettlementTransferService();
SendMoneyService : $sendMoney = $K2->SendMoneyService();
PollingService : $polling = $K2->PollingService();
ReversalService: reversalService = $K2->ReversalService();
PaymentLinkService: paymentLinkService = $K2->PaymentLinkService();

Usage

Tokens

You will need to pass an access token when sending data to Kopokopo's API.

This will return accessToken and expiresIn values

use Kopokopo\SDK\K2;

// Do not hard code these values
$options = [
  'clientId' => 'YOUR_CLIENT_ID', 
  'clientSecret' => 'YOUR_CLIENT_SECRET',
  'apiKey' => 'YOUR_API_KEY',
  'baseUrl' => 'https://sandbox.kopokopo.com'
];

$K2 = new K2($options);

// Get one of the services
$tokens = $K2->TokenService();

// Use the service
$result = $tokens->getToken();

//print the result
print_r($result);

Webhooks

Consuming

// TODO: review this
$router->map('POST', '/webhook', function () {
    global $K2;
    global $response;

    $webhooks = $K2->Webhooks();

    $json_str = file_get_contents('php://input');
    var_dump($json_str);

    $response = $webhooks->webhookHandler($json_str, $_SERVER['HTTP_X_KOPOKOPO_SIGNATURE']);

    echo json_encode($response);
});

Subscription

$webhooks = $K2->Webhooks();

//To subscribe to a webhook
$response = $webhooks->subscribe([
    'eventType' => 'buygoods_transaction_received',
    'url' => 'http://localhost:8000/webhook',
    'scope' => 'till',
    'scopeReference' => '000000',
    'accessToken' => 'my_access_token',
    'enableDarajaPayload' => 'false'
]);

print_r($response);

STK PUSH

$stk = $K2->StkService();
$result = $stk->initiateIncomingPayment([
                'paymentChannel' => 'M-PESA STK Push',
                'tillNumber' => 'K000000',
                'firstName' => 'Jane',
                'lastName' => 'Doe',
                'phoneNumber' => '0712345678',
                'amount' => 3455,
                'email' => 'example@example.com',
                'callbackUrl' => 'http://localhost:8000/test',
                'accessToken' => 'myRand0mAcc3ssT0k3n',
            ]);
print_r($result);

Services

The only supported ISO currency code at the moment is: KES

`TokenService`

$TokenService->getToken() to get an access token.

The response will have the following structure

[ 'status' => 'success',
  'data' => [
    'accessToken' => 'GT6576QGYdYh8i5s8DnxUQVphFewh-8eiO2',
    'tokenType' => 'Bearer',
    'expiresIn' => 3600,
    'createdAt' => '2021-04-06T13:49:50+03:00'
  ]
]

NB: The access token is required to send subsequent requests

$TokenService->revokeToken(['accessToken' => 'myRand0mAcc3ssT0k3n']) to revoke an access token.

NB: The access token cannot be used to send subsequent requests

$TokenService->introspectToken(['accessToken' => 'myRand0mAcc3ssT0k3n']) to introspect a token.

Responses and Results

All the post requests are asynchronous apart from TokenService. This means that the result will be posted to your custom callback url when the request is complete. The immediate response of the post requests contain the location url of the request you have sent which you can use to query the status.

Note: The asynchronous results are processed like webhooks.

To access the different parts of the response or webhook payload passed, use the following keys to access:
