HOW TO EMBED STACKVERIFY HTML + JS

Step 1: Add the following fields inside your <form> tag

<!-- 📌 Registration Input Fields -->
<input type="text" id="username" placeholder="Username" required />
<input type="email" id="email" placeholder="Email" required />
<input type="text" id="phone" placeholder="Phone Number" required />
<input type="password" id="password" placeholder="Password" required />

<!-- 📩 Button to Send OTP -->
<button id="sendOtpBtn">Send OTP</button>

<!-- 🔐 OTP Input Section (Initially hidden, shown after OTP is sent) -->
<div id="otpSection" class="hidden">
  <input type="text" id="otp" maxlength="6" placeholder="Enter OTP" />
  <button id="verifyOtpBtn">Verify OTP</button>
</div>

<!-- 📣 Message Display Area for Success or Errors -->
<p id="error"></p>

Step 2: Paste this script right before your </body> tag

<!-- 🚀 StackVerify OTP Script -->
<script 
  src="https://stackverify.vercel.app/otp.js" 
  data-company="YourCompanyName" 
  data-register-endpoint="https://yourdomain.com/register.php" 
  data-redirect="/dashboard.html">
</script>

📋 Step 1: Place the input fields inside your existing form where users will register. These fields will be used to collect the user's basic info before verifying their email.

🔐 Step 2: When the user clicks Send OTP, a 6-digit code will be emailed to them using StackVerify. They’ll enter it to verify.

📤 Step 3: Once OTP is verified, StackVerify automatically submits their data to your API (defined in data-register-endpoint).

➡️ Step 4: After registration, the user will be redirected to the URL set in data-redirect.

🔧 Tip: Customize the API endpoint and redirect path for each platform using script data-* attributes.
