The New Customer webhook fires when a first-time user logs in via FlexyPass and a new account is created for them on your store. This event is exclusive to FlexyPass — it does not fire if the user is merely identified without confirming login, and it is not triggered by FlexyPe Checkout.This webhook provides real-time customer data including contact details, enabling businesses to sync new customers with external CRMs, marketing platforms, or loyalty programs, and automate onboarding flows from the very first interaction.
