# Creating order details

After defining the fields required for the `PaymentRequest` object, provide the
order amount for a specific transaction.

To provide the order amount, define the `am` and `cu` fields in the payment request.
Because the `am` and `cu` fields are calculated based on the defined order values,
they'll vary for every order.

The contents of the `total` parameter should contain a `label` parameter
and an `amount` parameter consisting of a currency and value.

## Defining order value

The following code snippet illustrates how to add an order amount based on the
order. In this example, the static number '10.01' is provided as a value for the
`amount` variable.

    const details = {
      total: {
        label: 'Total',
        amount: {
          currency: 'INR',
          value: '10.01', // sample amount
        },
      },
      displayItems: [{
        label: 'Original Amount',
        amount: {
          currency: 'INR',
          value: '10.01',
        },
      }],
    };
