Twilio Verify alternative for WhatsApp OTP: Replio

Twilio Verify is the best-known verification API, and it does a lot: SMS, WhatsApp, voice, email, authenticator apps and fraud protection. If most of your users verify on WhatsApp, though, you may be paying a per-verification fee for channels you do not use. The Replio OTP service sends and checks codes on WhatsApp only, from your own number, at one price per delivered code. Here is an honest comparison.

Twilio Verify charges $0.05 per successful verification plus the channel fee, which for a WhatsApp code in the US comes to about $0.053. Replio sells prepaid OTP credits from $0.025 per delivered code, and it sits inside Replio, the AI customer support platform that also answers those users on WhatsApp, Instagram, Messenger and Telegram.

How the Replio OTP service works

You connect your WhatsApp Business number in the Replio dashboard, 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 moving from Twilio does not change your verification logic.
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, much like Verify's check call.
Test keys let you build the integration without sending real messages or spending credits.
Rate limits per recipient and a cap on wrong guesses per code protect your balance and your WhatsApp quality rating.

What the price difference looks like

At Twilio's listed US rate of about $0.053 per WhatsApp verification, 10,000 codes cost about $534. On Replio, 10,000 credits cost $300, and 50,000 cost $1,250 ($0.025 each) against about $2,670 on Twilio. Replio 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. Twilio offers volume discounts through its sales team, so very large senders should ask for a quote.

Why teams choose Replio for WhatsApp codes

No per-verification fee

You pay per delivered code, not a flat verification fee on top of the message, which is where most of the cost of a WhatsApp code on Twilio sits.

Your number, already set up

Connect your WhatsApp Business number from the dashboard in a few clicks, with no sender registration project, and the same number handles your customer conversations.

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 Twilio Verify might fit better

If you need SMS, voice, email or authenticator-app verification in one API, advanced fraud protection, or you already run everything on Twilio, Verify is the more complete product. Replio fits best when WhatsApp is how your users already talk to you and you want lower, simpler per-code pricing from your own number, with an SMS path of your own kept as the backup.
