Dexatel alternative for WhatsApp OTP: Replio

Dexatel and Replio can both send verification codes over WhatsApp, but they are built for different jobs. Dexatel is a multi-channel messaging platform with SMS, voice and other fallbacks. Replio's OTP service is WhatsApp-first: codes go out from your own verified business number, at one price per delivered code. Here is an honest comparison.

Dexatel sends messages and one-time passcodes through a single API across SMS, WhatsApp, Viber, Telegram, voice, flash call and email, and its Verify API can switch to another channel when a code does not get through. The Replio OTP service does one thing: it sends and verifies codes on WhatsApp, from the number your customers already know, and it sits inside Replio, the AI customer support platform that also answers those customers on WhatsApp, Instagram, Messenger and Telegram.

Replio vs Dexatel at a glance

Dexatel details are taken from its public website in September 2026 and may change. Always check Dexatel's own pricing for your destinations.

How the Replio OTP service works

You connect your WhatsApp Business number in Replio, pick an approved Authentication template from Meta's library, buy OTP credits and create an API key. Then it is one POST request:

• Pass your own code and Replio just delivers it, so your existing verification logic does not change.
• Or leave the code out and Replio generates a six-digit code, stores only its hash, expires it after the time you set and gives you a /api/otp/verify endpoint to check what the user typed.
• Test keys let you build the whole integration without sending real messages or spending credits.
• Rate limits per recipient stop one number being pumped with codes, which protects your balance and your WhatsApp quality rating.

The full reference is on the WhatsApp OTP API page.

Pricing, side by side

Replio sells OTP credits separately from your support plan, so a busy support month never blocks your sign-ins. 1,000 credits cost $35, 10,000 cost $300 and 50,000 cost $1,250, which is $0.035 down to $0.025 per code. Credits never expire, and only a delivered send uses one. Indonesia, the UAE and Malaysia cost two credits because WhatsApp charges much more to deliver there. There is no monthly WhatsApp fee on top.

Dexatel prices WhatsApp OTP per message by destination, starting from about $0.007, and lists a $28 monthly fee for WhatsApp alongside pay-as-you-go usage with no setup fee. At low volumes the monthly fee dominates; at very high volumes Dexatel's per-message rate can come out lower. Run your own numbers on both calculators before deciding.

Why teams choose Replio for WhatsApp codes

Codes from your own number

The code arrives in the same WhatsApp chat your customers use to talk to you, from your verified business name, not from an unfamiliar sender.

Verification without writing verification code

Let Replio generate and check the code and there is nothing to store on your side: no code table, no expiry job, no attempt counter.

Support in the same place

When a user replies to the code message with a question, Replio's AI agent answers from your knowledge base, and your team can step in from the same inbox.

When Dexatel might fit better

If you need SMS, voice or flash call in the same API, or automatic fallback when WhatsApp does not deliver, Dexatel covers channels Replio does not. That matters in markets where many users are not on WhatsApp. Replio fits best when WhatsApp is how your customers already talk to you and you want simple, per-code pricing from your own number, with an SMS path of your own kept as the backup.
