ZENGAPAY PHP Library

ZENGAPAY is a Payments Gateway service that enables businesses to receive payments from their customers via mobile money, as well as make mobile money payments to any mobile money account holder or purchase Mobile Airtime or Mobile Data.

This is the Official ZENGAPAY PHP Client Library

Getting Started

Prerequisites

To use the API, you must, first of all, have a ZENGAPAY Account.

We have production as well as test server environments. The test server environment is called sandbox.

You are advised to signup for a free account in sandbox, get your API Token by going to Settings → Developer Settings and test all your API calls on the sandbox environment before pointing your application to production.

To point an application to production, you need to signup for a free account in production then make only minor changes. In most cases, you simply need to change the API service URL and API TOKEN.

The API Endpoint for our sandbox environment is:

https://api.sandbox.zengapay.com/v1/

And the API Endpoint for our production environment is:

https://api.zengapay.com/v1/

Installing

The ZENGAPAY PHP Library is available via Composer/Packagist. So just add this line to your composer.json file

{
  "require": {
    "zengapay/zengapay-php": "*"
  }
}

composer require zengapay/zengapay-php:dev-master

Then inside your PHP script, add the line

require 'vendor/autoload.php';

Manual Installation

Alternatively, download the contents of the zengapay-php folder and uncompress it in a location that's on your project's include path.

Once that's done, include the library in your scripts as follows:

require_once '/path/to/zengaPayAPI.php';

Depending on your preferred environment, you can Instantiate the library as follows:

$zengaPayAPI = new zengaPayAPI("api.sandbox.zengapay.com"); // For Sandbox

$zengaPayAPI = new zengaPayAPI("api.zengapay.com"); // For Production

Please Note: If you don't explicitly specify the environment, by default the library shall use the production environment

Collections

ZENGAPAY uses the term Collections to refer to money that you receive (or collect) from a mobile subscriber. This differentiates money you receive (Collections) from money you send to mobile subscribers (Transfers).

Sample Payment Request (Collection)

The requestPayment method enables you to request/collect funds from your customer(s) or any mobile money account holder and deposit the funds into your ZENGAPAY account.

//require ZENGAPAY PHP Library
require_once '/path/to/zengaPayAPI.php';
   
//Instantiate the library
$zengaPayAPI = new zengaPayAPI();
$zengaPayAPI->setAPIKey("<YOUR_API_KEY>"); // Obtain this from your ZENGAPAY Dashboard (Settings -> Developer Settings)

$zengaPayAPI->msisdn = "256770000000";
$zengaPayAPI->amount = 15000;
$zengaPayAPI->external_reference = "Your Transfer Reference"; // eg #3001
$zengaPayAPI->narration = "Your Transfer Narration"; //eg Refund for Order #3001

$request = $zengaPayAPI->requestPayment();

if(isset($request->result->code) && ($request->result->code === 202))
{
    //Transaction was initiated successfully
    echo $request->result->transactionReference;  // You will need this to follow up on the status of the transaction in the next step
}
// If you wish, you may print to view the full response.
print_r($request);

Getting a Single Collection (Checking status of a collection request)

To retrieve a single collection object (check status of a collection request), provide the transactionReference and a collection object will be returned.

//require ZENGAPAY PHP Library
require_once '/path/to/zengaPayAPI.php';
   
//Instantiate the library
$zengaPayAPI = new zengaPayAPI();   
$zengaPayAPI->setAPIKey("<YOUR_API_KEY>");  // Obtain this from your ZENGAPAY Dashboard (Settings -> Developer Settings)

$zengaPayAPI->transactionReference = "<YOUR_TRANSACTION_REFERENCE>"; 

$request = $zengaPayAPI->getSingleCollection(); 
    
if($request->result->data->transactionStatus === "SUCCEEDED")
{
    //Transaction was successful and funds were deposited onto your ZENGAPAY Account. You can go a head to update your system. 
}
//If you wish, you may print_r to view the full response
print_r($request);

Getting All Collections

Use this method to retrieve a list of all collections on your account

//require ZENGAPAY PHP Library
require_once '/path/to/zengaPayAPI.php';
   
//Instantiate the library
$zengaPayAPI = new zengaPayAPI();
   
$zengaPayAPI->setAPIKey("<YOUR_API_KEY>"); // Obtain this from your ZENGAPAY Dashboard (Settings -> Developer Settings)

//$zengaPayAPI->status = ""; could be one of these:  FAILED,SUCCEEDED,PENDING
//$zengaPayAPI->per_page = 50;
//$zengaPayAPI->designation = ""; could be one of these : CHARGES,TRANSACTION
//$zengaPayAPI->start = "YYYY-MM-DD HH:MM:SS";
//$zengaPayAPI->end = "YYYY-MM-DD HH:MM:SS";

$request = $zengaPayAPI->getAllCollections();
  
print_r($request);

Transfers

ZENGAPAY uses the term Transfers to refer to money that you send to a mobile subscriber. This differentiates money you send to mobile subscribers (aka Transfers) from money you receive from mobile subscribers (aka Collections).

Sample Transfer Request (Payout/Withdraw)

The sendTransfer method enables you to send money to a any mobile money account holder or withdraw your funds (ZENGAPAY account balance) to your own Mobile Money account.

Example 1: Sending to Non Contact

//require ZENGAPAY PHP Library
require_once '/path/to/zengaPayAPI.php';
   
//Instantiate the library
$zengaPayAPI = new zengaPayAPI();
$zengaPayAPI->setAPIKey("<YOUR_API_KEY>"); // Obtain this from your ZENGAPAY Dashboard (Settings -> Developer Settings)

$zengaPayAPI->msisdn = "256770000000";
$zengaPayAPI->amount = 1500;
$zengaPayAPI->external_reference = "Your Transfer Reference"; // #3001
$zengaPayAPI->narration = "Your Transfer Narration"; //eg Refund for Order #3001

$request = $zengaPayAPI->sendTransfer();

if(isset($request->result->code) && ($request->result->code === 202))
{
    //Transaction was initiated successfully
    echo $request->result->transactionReference;  // You will need this to follow up on the status of the transaction in the next step
}
// If you wish, you may print to view the full response. 
print_r($request);

Example 2: Sending to a Contact

//require ZENGAPAY PHP Library
require_once '/path/to/zengaPayAPI.php';
   
//Instantiate the library
$zengaPayAPI = new zengaPayAPI();
$zengaPayAPI->setAPIKey("<YOUR_API_KEY>"); // Obtain this from your ZENGAPAY Dashboard (Settings -> Developer Settings)

$zengaPayAPI->amount = 1500;
$zengaPayAPI->narration = "Your Transfer Narration"; //eg Refund for Order #3001
$zengaPayAPI->external_reference = "Your Transfer Reference"; // #3001
$zengaPayAPI->use_contact = true;
$zengaPayAPI->contact_id = "9aa3bc79-583e-4eb5-93bf-0e894b07aec9";

$request = $zengaPayAPI->sendTransfer();

if(isset($request->result->code) && ($request->result->code === 202))
{
    //Transaction was initiated successfully
    echo $request->result->transactionReference;  // You will need this to follow up on the status of the transaction in the next step
}
// If you wish, you may print to view the full response.
print_r($request);

$zengaPayAPI = new zengaPayAPI();
    
$zengaPayAPI->setAPIKey("<YOUR_API_KEY>");
$transfer = $zengaPayAPI->getSingleTransfer("<YOUR_TRANSACTION_REFERENCE>");
  
if($transfer->result->data->transactionStatus === "SUCCEEDED")
{
   //Transaction was successful and funds were deducted from your ZENGAPAY Account. You can go a head to update your system. 
}
//If you wish, you may print_r to view the full response  
print_r($transfer);

Getting All Transfers

Related Webhooks

The collection.success and collection.failed events are triggered whenever something happens to a collection that you have initiated. For example, if it is successful or if it fails.

The transfer.success and transfer.failed events are triggered whenever something happens to a transfer that you have initiated. For example, if it is successful or if it fails.

You can configure a web link to receive notifications whenever this occurs. This will allow you to respond automatically whenever a collection or transfer is completed or whenever it fails.

See our Webhooks API documentation for more information.

You'll find plenty more to play with in the examples folder.

That's it! You should now be ready to use the ZENGAPAY PHP Library
