Learn about currency settings in Hyperline.
On the technical side, our APIs always represent currencies using their three-letter ISO 4217 code (see a complete list here). They accept and return integer amounts in the currency’s smallest unit. For European currencies, this means that amounts are represented in cents. To convert an amount with decimals into its Hyperline format, multiply it by 100. For example, Hyperline represents an amount of €34.17 (Euro, a two-decimal currency) as 3417. Hyperline also supports zero-decimal currencies and three-decimal currencies. In this case, you need to apply the right multiplier (or none). For example, Hyperline represents an amount of F CFA 12065 (West African CFA franc, a zero-decimal currency) as 12065.
