function getIntegrationServices($body){

    $response = null;

    if($body["isTest"]){
        //response from QA test db
        $response = array("services" => array("VALIDATE_CUSTOMER", "MERCHANT_SERVICES", "SUBMIT_PAYMENT"));

    }else {
        //response from live db

    }

    if($response != null)
        $response = json_encode($response);

    return $response;

}

/validateCustomer

This service is optional.
This service allows Paga to verify the existence of a customer in good standing with the merchant using several customer properties.

function validateCustomer($body){

    $response = null;

    if($body["isTest"]){
        //response from QA test db
        $response = array("status" => "SUCCESS", "message"=>"Test Message", "isValid"=>true, "firstName"=>"firstName",
            "lastName"=>"lastName", "lastPaymentDate"=>"2020-01-01", "accountStatus"=>"valid",
            "paymentDueDate"=>"2022-01-01", "isDisplayed"=>true);


    }else {

    }

    if($response != null)
        $response = json_encode($response);

    return $response;
}

/getMerchantServices

function getMerchantServices($body){

    $response = null;

    if($body["isTest"]){
        //response from QA db
        $response = array("merchantService" =>
            array("name"=>"Service name", "price"=>1200.23, "shortCode"=>"serviceCode", "productCode"=>"prodCode",
                "isPublic"=>true));

    }else {

        //response from live db

    }
    if($response != null)
        $response = json_encode($response);

    return $response;

}

/submitTransaction

function submitTransaction($body){

    $response = null;

    if($body["isTest"]){
        //response from QA test db
        $response = array("status"=>"SUCCESS", "uniqueTransactionId"=>"trxn_Id", "customerReference"=>"1234567", "merchantStatus"=>"SUCCESS", "message"=>"successful payment from merchant", "confirmationCode"=>"Code12345");

    }else {
