Multi-currency with a fixed exchange rate

By default, LX CloudPos uses BCCR’s official exchange rate for the day. If the business applies a fixed exchange rate (set at the start of the day, negotiated with the customer, etc.), it must be indicated explicitly in the tipoCambio field:

const TIPO_CAMBIO_DIA = 670.50;  // calculated at the start of the day
 
async function emitirEnDolares(idCliente, lineas) {
  return await emitirFactura({
    tipo: 'FacturaElectronica',
    idUsuario: 7,
    cliente: { idCliente },
    condicionVenta: '01',
    medioPago: '04',
    moneda: 'USD',
    tipoCambio: TIPO_CAMBIO_DIA,  // ← fixed
    lineas
  });
}

If tipoCambio is omitted and moneda isn’t CRC, LX CloudPos calculates it automatically using BCCR’s rate for the day.
