From the Authevo team
How we think about WhatsApp verification, honest pricing, and building verification infrastructure for Egypt and the wider MENA region.
Add TOTP two-factor with any authenticator app
A second, independent verification method: standard RFC 6238 TOTP works with Google Authenticator, Authy, or any compatible app. No message sent, no delivery cost — which is exactly why it’s priced at $0.002 per verification, a fifth of the WhatsApp rate.
Start verifying today, before Meta approves your WhatsApp
Sending WhatsApp authentication codes needs a one-time Meta Business Verification, which takes time. Here’s how to deliver codes over Telegram in minutes and flip WhatsApp on automatically the moment you’re verified.
Verify Authevo webhooks with the HMAC signature
Every webhook Authevo sends is signed with an HMAC-SHA256 header keyed by your account secret. Here’s how to verify it in a few lines, so your server only trusts events that genuinely came from us.
WhatsApp OTP in Egypt: a developer’s guide
Why WhatsApp is the most reliable OTP channel in Egypt, what you need to send codes from your own number, and how to integrate it in two API calls — with pay-per-success pricing you top up in EGP.
Verify a phone number in two API calls
A short, copy-paste walkthrough of the whole flow: POST /v1/otp/send to deliver a code over WhatsApp, then POST /v1/otp/verify to check it. No SDK required, two endpoints, JSON in and out.
Why we charge per successful verification
Our pricing centers on the successful verification — $0.01 each, no monthly seat — with a per-message starting tier for new accounts. Here’s how that tier, prepaid credit, and the Safety Floor fit together, and why pay-per-success aligns our incentives with yours.
Why we built Authevo: WhatsApp OTP for Egypt & MENA
SMS OTP is expensive and unreliable across MENA, while WhatsApp is where everyone already is. We built a developer-first verification API around WhatsApp — with automatic Telegram fallback and pay-for-success pricing.
