OTP verification session and status workflow

Reduce risk at critical account moments

Phone-based verification helps businesses confirm user intent before account access, payment approval, profile changes, and recovery flows turn into operational risk.

Account quality

Reduce fake account creation

Verify phone numbers during onboarding so product teams can reduce low-quality signups and keep account creation tied to a reachable customer.

Account protection

Challenge risky access attempts

Add OTP checks to logins, device changes, and password resets to reduce exposure to account takeover and unauthorized access.

Transaction risk

Approve high-impact actions

Require verification before transfers, payment approvals, profile edits, or support-assisted recovery when the action carries business or customer risk.

Use cases

Verification for the account flows customers depend on

Add OTP sessions to the points where a phone number should confirm user identity, transaction intent, or account ownership.

Onboarding

Signup verification

Confirm that a new user controls the phone number attached to their account before they enter your marketplace, app, or customer platform.

Access

Login verification

Challenge suspicious logins, new-device access, or policy-driven login events with a one-time code sent by SMS.

2FA

Two-factor authentication

Add a second verification step for accounts where password-only authentication is not enough for the risk profile.

Payments

Payment and transfer approval

Verify customer intent before money movement, withdrawals, payment approvals, or other actions that should not rely on an active session alone.

Recovery

Password reset and account recovery

Confirm account ownership when customers reset passwords, recover access with support, or return after changing phones or SIMs.

Number ownership

Phone number verification

Check that a customer controls the number they use for account access, alerts, payment approval, or service notifications.

Account changes

High-risk profile and device changes

Require verification before customers change recovery details, add a new device, update phone numbers, or modify sensitive profile data.

Support

Support-assisted verification

Give support teams a verification step when they help customers recover access or confirm ownership before changing account data.

API workflow

Create, send, check, and record OTP sessions

Flowdacity Verify is designed around session-based verification. Product teams request a verification, the user receives an SMS code, and your application checks the submitted code through the API before approving the action.

Create a verification session

Start a session with the customer's phone number, purpose, and SMS channel so the verification attempt is tied to a specific product action.

Send the OTP by SMS

Deliver a one-time passcode to the phone number attached to the user, account, transaction, or recovery request.

Validate the submitted code

Check the customer's OTP through your backend before completing the login, signup, payment, profile update, or recovery flow.

Receive status events

Use verification status and webhook events to update internal systems, support tooling, audit trails, and customer-facing state.

Delivery and verification visibility for operational teams

Verification is not complete when a code is sent. Product, engineering, and support teams need status context to understand what happened and what the customer should see next.

Delivery status

Sent, delivered, and failed attempts

Track delivery outcomes where available so teams can separate user input errors from message delivery issues.

Verification result

Verified, failed, and expired sessions

Keep application state aligned with the result of the OTP check so customers are approved, challenged again, or moved to support.

Webhooks

Events for internal systems

Use webhook events to update dashboards, support views, audit logs, and risk systems without relying on manual investigation.

Developer workflow

API-first OTP sessions

Keep verification logic in your backend. Create a session when a product action needs confirmation, then check the customer-submitted code before approving the request.

Create a verification session

POST /v1/verify/sessions

{
  "phone_number": "+2348012345678",
  "purpose": "login",
  "channel": "sms"
}

Check the customer code

POST /v1/verify/sessions/{session_id}/check

{
  "code": "482931"
}

Built for mobile-first African markets

African businesses need authentication flows that account for mobile-first users, local delivery conditions, changing devices, and support scenarios that often begin with a phone number.

Mobile-first products

Verification tied to the phone number

Use SMS OTPs in products where the phone number is central to login, customer communication, account recovery, and transaction approval.

Local behavior

Designed for changing user context

Account for customers who replace devices, change SIMs, move across networks, or need support to confirm ownership before access is restored.

Business workflows

Useful across regulated and operational flows

Apply OTP verification in fintech, marketplaces, logistics, SaaS, healthcare, and customer platforms where access and approval flows need stronger confirmation.
