OTP & Identity Verification

Verify users over SMS, email, or WhatsApp with OTP delivery workers and Flow-embedded verification steps.

Elevator pitch

Add secure sign-in, step-up auth, and account recovery with a single Verify API to deliver codes on the channel your user prefers and embed checks inside Flow journeys.

The problem

  1. Teams maintain separate OTP providers per channel.
  2. Verification status is disconnected from onboarding and support flows.
  3. Compliance requires audit trails for every verification attempt.

How Syntra solves it

  1. Verify service handles request, check, and status with idempotent APIs.
  2. Route and Engage deliver OTP via SMS, email, or WhatsApp templates.
  3. Flow verify nodes embed OTP steps inside commerce, KYC, and banking menus.
