When working with a sandbox account, there are constraints on the currency amounts you can use in test transactions. The amounts, by default, must be in the range 0.25 to 130.00 or the transaction will be declined due to amount too low/too high.
Some amounts are 'special' and invoke a particular response when processed.
|Amount (Major Units)||Result|
|10.27||Partial Approval (for 10.00)|
|47.27||Partial Approval (for 40.00)|
*Note: Minimum, maximum and special amounts all apply to the test platform only. These amounts do not create the same behavior on the live platform.
