Why is the amount of the payment I created different from the amount that was actually charged?

All amount values must be formatted in that currency’s smallest unit, AKA, Minor Units.

For example:

• Two-decimal currency (like US Dollars): $10.95 USD, amount will be 1095:

  • {
     "currency": "USD",
     "amount": 1095
    }

• Zero-decimal currency (like Japanese Yen): ¥1095 JPY, amount will be 1095:

  • {
     "currency": "JPY",
     "amount": 1095
    }

ISO 4217 is a standard first published by International Organization for Standardization in 1978, which delineates currency designators, country codes (alpha and numeric), and references to minor units.
