Customer will be redirected back to this URL when he cancels the checkout on MPower website

MPower_Checkout_Store::setCancelUrl(CHECKOUT_CANCEL_URL);

MPower will automatically redirect customer to this URL after successfull payment. This setup is optional and highly recommended you dont set it, unless you want to customize the payment experience of your customers. When a returnURL is not set, MPower will redirect the customer to the receipt page.

MPower_Checkout_Store::setReturnUrl(CHECKOUT_RETURN_URL);

Create your Checkout Invoice

$co = new MPower_Checkout_Invoice();

Create your Onsite Payment Request Invoice

co = new MPower_Onsite_Invoice();

Params for addItem function addItem(name_of_item,quantity,unit_price,total_price,optional_description)

$co->addItem("13' Apple Retina 500 HDD",1,999.99,999.99);
$co->addItem("Case Logic laptop Bag",2,100.50,201,"Black Color with white stripes");
$co->addItem("Mordecai's Bag",2,100.50,400);

Set the total amount to be charged ! Important

$co->setTotalAmount(1200.99);

Optionally set an invoice description

$co->setDescription("This is good for packaged pricing tables on your website.");

Setup Tax Information (Optional)

$co->addTax("VAT (15)",50);
$co->addTax("NHIL (10)",50);

You can add custom data to your invoice which can be called back later

$co->addCustomData("Firstname","Alfred");
$co->addCustomData("Lastname","Rowe");
$co->addCustomData("CartId",929292872);

Redirecting to your checkout invoice page

if($co->create()) {
   header("Location: ".$co->getInvoiceUrl());
}else{
  echo $co->response_text;
}

Onsite Payment Request(OPR) Charge

First step is to take the customers mpower account alias, this could be the phoneno, username or mpower account number. pass this as a param for the create action of the MPower::Onsite::Invoice class instance. MPower will return an OPR TOKEN after the request is successfull. The customer will also receieve a confirmation TOKEN.

    if($co->create("CUSTOMER_MPOWER_USERNAME_OR_PHONE")) {
       $opr_token = $co->token;
    }else{
      echo $co->response_text;
    }

Second step requires you to accept the confirmation TOKEN from the customer, add your OPR Token and issue the charge. Upon successfull charge you should be able to access the digital receipt URL and other objects outlined in the offical docs.

if($co->charge("OPR_TOKEN","CUSTOMER_CONFIRM_TOKEN")){
    $receipt = $co->receipt_url;
    $customer_name = $co->customer["name"];
}else{
    echo $co->response_text;
}

DirectPay Request

You can pay any MPower account directly via your third party apps. This is particularly excellent for implementing your own Adaptive payment solutions on top of MPower.

$direct_pay = new MPower_DirectPay();
if ($direct_pay->creditAccount("MPOWER_CUSTOMER_USERNAME_OR_PHONENO",70.65)) {
  echo $direct_pay->description."\n";
  echo $direct_pay->response_text."\n";
  echo $direct_pay->transaction_id."\n";
}else{
  echo $direct_pay->response_text."\n";
}
