Frequently asked questions
What is an OTP service?
An OTP service sends a short-lived one-time code to verify that a user controls a phone number before a sensitive action is completed.
Can I use both SMS and WhatsApp OTP?
Yes. Your form can present SMS and WhatsApp as verification options when both channels are configured and available.
Does PK SMS support WooCommerce OTP?
Yes. OTP can be integrated with WooCommerce registration, login, checkout and order-confirmation workflows.
What happens if the notification gateway fails?
A reliable implementation should preserve the customer action or enquiry where appropriate, log the failure and provide a controlled retry or fallback process.
