The string is generated from order parameters with semicolon as delimiter.
For merchants using the standard interface, the following parameters are included in the string:
Merchant _ ID;OrderNumber;OrderAmount;OrderCurrency
If the merchantuses any additional parameters, then the string is generated according to the following rules:
fields are added to the main string through the delimiter in the order specified in the table below;
fields are included in the string only if they are transferred in the order and have nonzero values;
if the parameter is not transferred in the order or the value 0 is transferred, then both the parameter and the delimiter are not added to the string.
