Data Types

## Dates and Time Zones API responses from Advanced Billing are sent with the timezone of the current Advanced Billing site. Alternately, webhooks sent from Advanced Billing globally use EST (Eastern Standard Time) as the timezone for all content in the body of the payload. For requests, If only a date is provided: Advanced Billing uses noon in the site’s time zone If date and time are provided, Advanced Billing uses the time of day in the site’s time zone. If date/time/timezone is provided, Advanced Billing uses that absolute date and displays it in the site’s time zone. ## Decimal Numbers In order to prevent losing precision, we serialize decimal numbers as strings instead of as JSON numbers. We recommend parsing these strings into their decimal equivalent using a decimal number library in your programming language (for example, `BigDecimal` in Ruby) instead of relying on floating point values or arithmetic. ## Amount Fields and Currency Fields holding amount values are given as a string representing a decimal whole currency amount. For example, `"1.23"` in currency `"USD"` would equate to `$1.23`. Not all fields will be rounded to the smallest currency denomination. Intermediate results, such as those that derive from line-level tax calculations, may hold precision up to 8 decimal places. However, the top-level totals we provide (e.g., `total_amount`) will be rounded to the smallest currency denomination. It is up to API consumers to parse the string into a decimal number representation and do any rounding necessary for your application.
