Amounts and units
Sendamount in major units by default: 4.01 for 4.01 USD/EUR. API clients that already send cents can set amount_unit: "MINOR" at the root of the JSON body, alongside amount and currency, rather than in metadata. Public responses return major units even when the request uses MINOR. See amounts and currencies.
Workflow
1. Create the intent
fee and required_total. Your wallet must cover amount + fee.
