Implementation Options

For Message-based verifications (WhatsApp Message and Telegram Message), we handle deep linking in two ways:

Deep Link Behavior:

  • On Mobile Devices: The deep link automatically redirects users to the WhatsApp/Telegram app
  • On Web, Desktop, and other devices (like POS): A QR code is displayed for users to scan with their mobile devices to open the corresponding messaging app

Note: For OTP-based verifications (WhatsApp OTP, Telegram OTP, SMS OTP), the implementation is straightforward as it only requires displaying input fields for phone number and verification code.
