Question

I am sending amount 2EUR to the gateway and now it replace with 0,02. Which causing wrong amount is being received at ideal and testing status is not getting update.

$amount = 2;    
$newAmount = 2.2;

What could have cause this ?

Answer 1

You need to multiple amount by 100

As mentioned in its documentation.

All amounts (amount, itemPrice) should be given in whole eurocents.
Therefore, for a product costing 1 euro you should enter “100“ as the
price. Decimals are not accepted.
