📲

User sends the code

User taps the button. Their app opens with the code pre-filled. They tap send.

⚡

Verified instantly

Your app receives a real-time webhook. User is verified. No polling needed.

Why AkidOTP

Built different

Most verification APIs charge per SMS. We use the free messaging apps your users already have — with SMS as a last-resort fallback.

💬

WhatsApp verification

User sends a code via WhatsApp — the app they already have open all day. Near-zero cost to you. Works everywhere WhatsApp works. On Android, the API returns separate links for WhatsApp Personal and WhatsApp Business so users always open the right app — preventing number mismatch errors.

✈️

Telegram verification

Completely free. User sends code to our bot in one tap. Instant verification. Popular across the Middle East, Central Asia, and Europe.

✉️

Email OTP fallback

Always available. When users have neither WhatsApp nor Telegram, email OTP is the safety net. Free tier includes 1,000/month.

📱

SMS fallback

For the rare case where a user has no WhatsApp, Telegram, or email — SMS is the last resort. The user sends a pre-filled text message to verify their number. Available on Starter plans and above with monthly limits to keep your costs predictable.

💰

Flat monthly pricing

No per-message charges. No surprise bills at month end. Pay a flat fee and verify as many users as your plan allows.

🌍

Works worldwide

SMS delivery fails in many countries. WhatsApp and Telegram work everywhere. AkidOTP reaches users that traditional SMS providers cannot.

🔒

Secure by default

Phone number ownership verified at the messaging app level. Sessions expire in 2 minutes. Anti-forwarding checks built in.

Channel comparison

What your users pay per verification

AkidOTP charges you a flat monthly fee. But SMS costs your end users money from their carrier. That's why WhatsApp and Telegram are better — free for everyone.

Channel	Cost to you	Cost to your user	Best for
💬 WhatsApp	$0.00	Free	MENA, Europe, Asia, Africa
✈️ Telegram	$0.00	Free	Central Asia, Eastern Europe, MENA
✉️ Email	$0.00	Free	Universal fallback
📱 SMS	Included in plan	~$0.04–$0.23	Last resort — no apps, no email

REST API — any language

Python, PHP, Ruby, Go, Dart — if it can make HTTP requests, it works.

verify.js

              // Start verification — returns WhatsApp + Telegram links
              const res = await fetch('https://akidotp.com/api/mobileverify/start', {
              method: 'POST',
              headers: {
              'X-API-Key': 'YOUR_API_KEY',
              'Content-Type': 'application/json'
              },
              body: JSON.stringify({ phone: '+447911234567' })
              });

              const data = await res.json();
              // data.whatsappLink — universal (iOS, desktop, fallback)
              // data.whatsappPersonalLink — Android intent → WhatsApp Personal
              // data.whatsappBusinessLink — Android intent → WhatsApp Business
              // data.telegramLink — Telegram bot link

              const isAndroid = /android/i.test(navigator.userAgent);

              if (isAndroid && data.whatsappPersonalLink) {
                // Show a chooser — let user pick Personal or Business WhatsApp
                // This prevents "Number mismatch" on dual-WhatsApp devices
                showWhatsAppChooser(data.whatsappPersonalLink, data.whatsappBusinessLink);
              } else {
                // iOS / desktop — open universal link directly
                window.open(data.whatsappLink, '_blank');
              }
              // User taps, sends code, verified ✓
            

Android smart routing

Two WhatsApp apps. Zero confusion.

In the MENA region, many users have both WhatsApp Personal and WhatsApp Business installed on the same phone — often on different numbers. The AkidOTP API returns separate intent links for each app. Show your users a simple chooser and eliminate number mismatch failures entirely.

Make sure to open the app linked to your number

WhatsApp Personal

com.whatsapp

WhatsApp Business

com.whatsapp.w4b

iOS users see a single button — only one WhatsApp exists on iOS

① API returns 3 WhatsApp links

                whatsappLink       → universal (iOS +
                  desktop)

                whatsappPersonalLink → Android: WhatsApp Personal

                whatsappBusinessLink → Android: WhatsApp
                  Business
              

② Detect Android — show the right UI

                const isAndroid = /android/i.test(navigator.userAgent);

                if (isAndroid && data.whatsappPersonalLink) {

                  // show 2-button chooser

                  openPersonal(data.whatsappPersonalLink);

                  openBusiness(data.whatsappBusinessLink);

                } else {

                  // iOS / desktop

                  window.open(data.whatsappLink);

                }

③ If app isn't installed — graceful fallback

If the user only has WhatsApp Personal and taps the Business button, Android automatically opens the universal wa.me link instead. Nothing breaks.

Verify once. Trust always.
