    Row row = sheet.getRow(rowNum);
    if ( row==null ) {
         return null;
    }
    else {
         Cell cell = row.getCell(colNum);
         if ( cell==null ) {

         else {
             return getCellValue(cell);
         }
    }
 
}
public Object getCellValue(Cell cell) {
switch (cell.getCellTypeEnum()) {
case CellType.STRING:
    return cell.getRichStringCellValue().getString();
case CellType.NUMERIC:
    if (DateUtil.isCellDateFormatted(cell)) {
        return cell.getDateCellValue();
    } else {
        return cell.getNumericCellValue();
    }
case CellType.BOOLEAN:
    return cell.getBooleanCellValue();
case CellType.FORMULA:
    return evalCell(cell); 
case CellType.BLANK:
return null;
default:
throw new IllegalStateException("Unknown cell type");
}
 
private Object evalCell(Cell cell) {
 
FormulaEvaluator evaluator = cell.getSheet().getWorkbook().getCreationHelper().createFormulaEvaluator();
 
CellValue cellValue = evaluator.evaluate(cell);
 
switch (cellValue.getCellType()) {
    case Cell.CELL_TYPE_BOOLEAN:
        return cellValue.getBooleanValue();
    case Cell.CELL_TYPE_NUMERIC:
        return cellValue.getNumberValue();
    case Cell.CELL_TYPE_STRING:
        return cellValue.getStringValue();
    case Cell.CELL_TYPE_BLANK:
        return null;
    case Cell.CELL_TYPE_ERROR:
        throw new RuntimeException("Excel formula error");
    default:
    throw new IllegalStateException("Unknown cell type");

Hi,

1) I want to integrate Apple Pay on my website (so it's a Apple Pay - Web Integration), using the Braintree payment provider, JS as a client side language and Java as a server side language.

I'm having difficulties creating a proper sandbox environment for my Apple Pay implementation Testing.

Followed the steps from the Apple docs but it seems they are not accurate :

-says to create a Merchant Id, one for sandbox and one for production (as far as I can see, at the moment of creating those 2, there's no way of telling that you want to use one for the development environment and the other for the production)
- after that, says to create a Certificate using the Merchant ID created before; if I sign in to my Apple Developer Account, I can see the 'Development' and the 'Production' sections, but when I try to create a sandbox/development certificate, Apple Pay is not available for it, only in the production section (see below images).

Is there a way to create a Sandbox / Development Apple Pay certificate, or are there any other ways to properly test the Apple Pay integration ?

2) I tried creating a sandbox user tester account from iTunes, but when I tried to login on Itunes on my Ipad which I'm using for testing, I get the following error: 'Itunes account creation not allowed. This Apple ID cannot be used with the Itunes Store at this time. Please try again later.' (I already verified my Apple ID and followed all the steps to activate the account, but without any success)

3) As I was trying to create Sandbox Apple Pay certificates I mistakenly created 2 for the production environment. Could I revoke them without any problems and create another ones ?

If you integrated Apple Pay on the WEB, I would highly appreciate any help, since I'm having such difficulty in simply setting up my testing environment.
