Working with amounts
All monetary values are integers in the currency’s smallest unit (for PHP, centavos). For example,150000 represents PHP 1,500.00. There are no decimals.
This documentation targets the sandbox environment. Use an API key provisioned for sandbox; no real money is moved. See Testing for sandbox cards and scenarios.
