Send money as an integer with its currency
Send amounts as an integer count of the currency's smallest unit, together with the ISO 4217 currency code. Never use floating-point numbers for money.
How to do it
Write 129.50 Swedish kronor as { "amount": 12950, "currency": "SEK" }. Floats can't store 0.1 exactly, so sums drift. A decimal string such as "129.50" also works, if the whole API uses it. Store it with exact types.
Example
{ "total": { "amount": 12950, "currency": "SEK" } }How to check
Search the OpenAPI file for money fields typed number. None remain, and each has a currency beside it.
