Data types

Make requests to the Paddle API in JSON. Paddle responds in JSON.

The Paddle API uses JSON formatted data for requests and responses.

When making requests, specify application/json as your Content-Type. For example:

Paddle always sends responses as JSON. This includes errors as well as success responses.

Dates and times

All dates and times use the RFC 3339 format. For example:

Time and dateRFC 3339
3:30pm on March 20th 20242024-03-20T15:30:00.00Z
2am on January 12th 20252025-01-12T02:00:00.00Z
8:50pm on October 12th 20252025-10-12T20:50:00.00Z

Timezones

Paddle lets you sell globally in over 200 countries, so dates and times are UTC.

Money

Monetary values are returned as strings in the lowest denomination for a currency. For example, the API returns values in cents for USD and pence for GBP.

Many currencies have two decimals, but this can vary. For example:

CurrencyDecimalsExampleValue
USD2$24.99"2499"
JPY0¥1000"1000"

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 convenience, the preview prices operation returns formatted_unit_totals and formatted_totals objects alongside objects that return totals in the lowest denomination for a currency. Formatted totals objects return values formatted for the country or region you're working with, including the currency symbol.

Custom data

You can add custom data to some entities in Paddle. Custom data must be valid JSON.
