Dates and times
All dates and times use the RFC 3339 format. All dates are handled as UTC.Money and currencies
Monetary values are returned as integers in the lowest denomination for a currency. Example cents for USD.
We recommend using a currency library to format monetary values to the correct number of decimals. They can also help you format values for different locales and currency standards, making sure that currency symbols are placed correctly and the correct decimal separator is used.
For a full list of supported currencies and their decimals, see: Supported currencies.
