SMS OTP

Fast passcode delivery and verification in two API calls

Priority OTP routing. Route verification codes over direct carrier connections across 190+ countries so users can complete sign-in and checkout before codes expire.

Managed code lifecycle. Generate one-time passcodes, enforce expiration windows, and limit verification attempts through the Verify API without storing plain-text codes in your database.

Registered local senders. Deliver OTPs from pre-registered alphanumeric sender IDs, short codes, toll-free numbers, or local numbers to reduce carrier filtering.

Voice and WhatsApp fallback. Automatically retry undelivered SMS passcodes over text-to-speech Voice calls, WhatsApp, or Email so users are not locked out.

Pertanyaan yang Sering Diajukan

Seberapa cepat OTP dikirimkan?

Bird routes OTP traffic over priority carrier paths so time-sensitive passcodes arrive within seconds during sign-in or payment confirmation.

How does Bird's Verify API handle code validation?

Call one endpoint to generate and send the passcode, and a second endpoint to verify the code entered by the user. Bird enforces TTL expiration and attempt limits automatically.

Can I customize OTP message templates?

Yes. Customize your sender ID, message copy, language, code length, and expiration window to match your brand and platform autofill formats.

Tingkat pengiriman apa yang bisa saya harapkan?

Bird achieves 99% delivery rates across direct carrier connections and provides per-attempt delivery status codes.

How do you handle failed SMS deliveries?

Track delivery receipts in real time and configure fallback rules to resend the passcode via Voice, WhatsApp, or Email if the SMS does not arrive within your timeout window.

Can I integrate SMS OTP with my existing auth system?

Yes. You can either use the Verify API to manage code generation and checking, or generate codes in your own identity provider and send them through the SMS API.
