STK-Push

1. Below is a use case on how to request for payment via STK-Push.

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use MPESA\Services\OnlinePaymentService;

class PaymentController extends Controller
{
    public function requestPayment(Request $request,OnlinePaymentService $stk)
    {
        // phone number
        $user_phone_number = "254712345678"; # insert user phone number
        $amount = 50; # insert amount payable

        // this is optional if you want to overide the IPN on your .env
        $stk->callBackURL = "http://8bbea5f4.ngrok.io/api/mpesa/response-callback";
        
        // request for payment
        $stk->initiateSTKCheckout($amount,$user_phone_number);

    }
}

2. Set up your call back incase of successfull or cancelled payments . Your callback url should match the .env variable MPESA_CALLBACK_URL or $stk->callBackURL override. For more information on the json response from MPESA visit here

3. Otherwise here is a sample of the IPN callback

 // A cancelled request
  {
    "Body":{
      "stkCallback":{
        "MerchantRequestID":"8555-67195-1",
        "CheckoutRequestID":"ws_CO_27072017151044001",
        "ResultCode":1032,
        "ResultDesc":"[STK_CB - ]Request cancelled by user"
      }
    }
  }
  
  // An accepted request
  {
    "Body":{
      "stkCallback":{
        "MerchantRequestID":"19465-780693-1",
        "CheckoutRequestID":"ws_CO_27072017154747416",
        "ResultCode":0,
        "ResultDesc":"The service request is processed successfully.",
        "CallbackMetadata":{
          "Item":[
            {
              "Name":"Amount",
              "Value":1
            },
            {

              "Value":"LGR7OWQX0R"
            },

              "Value":20170727154800
            },
            {
              "Name":"PhoneNumber",
