OTP delivery features
Fast OTP delivery built around application verification
Use OTP as part of the authentication flow itself. Codory connects the gateway, API authentication, message rules and response handling so your application can send and verify codes cleanly.
HTTP & JSON API
Integrate OTP requests through developer-friendly HTTP/REST-style endpoints and structured JSON responses where supported.
DND-route Support
Use verification-oriented service routes designed to reach eligible DND numbers where carrier and regulatory rules permit.
API Key Authentication
Protect gateway calls with API credentials and server-side request validation rather than exposing credentials to end users.
Failover SMS Routing
Design retry or alternate-route handling for failed sends, provider errors and delivery issues when your gateway setup supports it.
24x7 Support
Get integration and operational assistance for important verification flows, API issues and production troubleshooting.
Technical specification
High-performance OTP gateway capabilities
A practical technical foundation for modern applications that need fast verification, controlled API access and observable delivery behavior.
How it works
From API request to verified user
The OTP workflow should be fast for genuine users and controlled enough to prevent abuse. The integration can enforce expiry, resend timing, attempt limits and delivery-status handling.
Request
Your application sends the mobile number, template context and verification request.
Authenticate
The gateway request is checked using the configured API credentials and required parameters.
Route
The OTP message is passed to the selected verification route with retry or failover logic where available.
Deliver
The carrier delivery response is captured so your application or logs can track the message state.
Verify
Your application validates the code against expiry and attempt rules, then continues the user action.

Where OTP fits
Verification for modern applications and business systems
OTP SMS can protect customer accounts and sensitive actions across consumer applications, SaaS products, ecommerce, financial workflows and internal systems.
Registration & onboarding
Confirm a mobile number before creating or activating a new account.
Login verification
Add OTP to passwordless login, two-step authentication or risky sign-in flows.
Password recovery
Verify account ownership before allowing a password reset or recovery action.
Ecommerce verification
Confirm customer numbers, important orders or account-linked checkout actions.
Transaction alerts
Use OTP for payment, wallet, payout or other high-value transactional workflows.
Business portals
Add verification to staff, reseller, partner or customer portal access.
Built for production workflows
What technical teams usually need from OTP delivery
Instead of publishing unverified customer quotes, we focus on the operational qualities that matter during integration and production use.
Low-latency delivery path
Keep verification screens responsive by minimizing unnecessary application-side delays.
Clear API responses
Use gateway responses and error states to decide retries, fallbacks and user-facing messages.
Controlled verification logic
Apply expiry, resend delays and attempt limits around the OTP itself.
Fast OTP SMS delivery for applications
Connect OTP verification to your application.
Share your platform, backend language, verification use case and expected traffic. We can map the API integration, routing requirements and production workflow without adding a pricing table to the page.
OTP SMS FAQs
Questions about OTP delivery, API access and setup
Practical answers for development teams evaluating OTP SMS for verification and authentication workflows.
Can I request a demo or test integration before going live?
Yes. For suitable projects we can first validate the API flow, request format and delivery response pattern before the production integration is finalized.
Do I need DLT registration for OTP SMS in India?
DLT requirements depend on the route, sender identity, template and use case. Codory can help map the correct setup, but final telecom and operator requirements still apply.
How quickly can an OTP SMS integration be activated?
If your application flow and provider credentials are ready, API integration can be completed quickly. Production activation time can also depend on route, sender and compliance approvals.
Can I use my own OTP message template?
Yes, subject to the route and telecom template requirements. We can connect your approved template to login, registration, password reset, payment or other verification events.
Why can sender names or IDs differ on some OTP routes?
Sender presentation depends on the SMS route, operator rules and the sender configuration available for that route. We can explain the expected sender behavior before production use.
Can the OTP route be used for promotional SMS too?
OTP traffic should remain focused on verification and authentication. Promotional or campaign messaging is better handled through the Bulk SMS service and the appropriate compliant route.
Do you provide HTTP or JSON API integration?
Yes. OTP workflows can be connected through HTTP/REST-style requests with API-key authentication and JSON responses where supported by the upstream gateway.
How fast is OTP delivery?
The integration is designed for low-latency delivery, but final delivery time depends on carrier routing, destination network conditions and the upstream messaging provider.
Can OTP messages reach DND numbers?
OTP and service-message delivery can use routes intended for verification traffic, including DND-compatible delivery where the selected provider and telecom rules permit it.
Can I use my own Sender ID?
Where the selected route supports a registered or approved Sender ID, we can configure it. Availability and approval requirements depend on the provider, operator and regulatory setup.
