Best Practices

Data Privacy: The client form event doesn’t include personal information (name, email) at this stage. This data is only available in the confirmation step.
Currency Handling: Always use the userCurrency field for conversion tracking to ensure accurate revenue reporting in multi-currency setups. The currency field represents the hotel’s base currency, while userCurrency is the actual transaction currency used by the guest.
