From the Authevo team
How we think about WhatsApp verification, honest pricing, and building verification infrastructure for Egypt and the wider MENA region.
Switching your OTP provider to Authevo
Two endpoints, a flat published rate, and a shared WhatsApp number you can send on today — no WhatsApp Business setup, no waiting on Meta. What actually changes in your code, and a checklist for the switch.
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 is sent, so it is a flat $0.002 per verification — one-fifth of the steady-state Egypt and own-number software rate.
Start verifying today, before Meta approves your WhatsApp
Sending WhatsApp authentication codes from your own number needs Meta Business Verification. Here’s how to link recipients once for Telegram delivery while you wait, then switch WhatsApp on automatically.
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 a strong OTP channel in Egypt, how the two-call integration and linked-recipient Telegram fallback work, and how staged billing moves to country-priced pay-per-success.
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
The first 50 successes are free; new accounts then pay per message until 500 successes before moving to country-priced pay-per-success. Here is how the ladder, prepaid credit, and Safety Floor fit together.
Why we built Authevo: WhatsApp OTP for Egypt & MENA
SMS OTP is expensive and unreliable across MENA. We built a WhatsApp verification API with Telegram fallback after one-time recipient linking, plus a transparent free, per-message, then country-priced ladder.
