How to integrate
Follow these WordPress-specific instructions
Get your Waitlister endpoint URL
Sign into Waitlister → navigate to Overview → copy your waitlist key. Your form action URL will be:https://waitlister.me/s/YOUR_WAITLIST_KEY
Create your waitlist form in WordPress
In your WordPress page/post editor, add an HTML block (Gutenberg) or HTML widget (page builders). Paste this basic form structure:
<form action="https://waitlister.me/s/YOUR_WAITLIST_KEY" method="POST">
<input type="email" name="email" placeholder="Your email" required>
<input type="text" name="name" placeholder="Your name">
<button type="submit">Join Waitlist</button>
</form>Add additional form fields (optional)
Customize your form by adding more fields. Any field name beyond email, name, and phone will be saved as custom metadata:
<input type="tel" name="phone" placeholder="Phone (optional)">
<input type="text" name="company" placeholder="Company">
<select name="role">
<option value="">Select role</option>
<option value="founder">Founder</option>
<option value="developer">Developer</option>
<option value="designer">Designer</option>
</select>
<textarea name="comments" placeholder="Tell us more"></textarea>Style your form with WordPress CSS
Add custom CSS to match your theme. Go to Appearance → Customize → Additional CSS. Here's a starter template:
/* Waitlist form styling */
.waitlist-form {
max-width: 500px;
margin: 0 auto;
}
.waitlist-form input,
.waitlist-form textarea,
.waitlist-form select {
width: 100%;
padding: 12px 16px;
margin-bottom: 12px;
border: 1px solid #ddd;
border-radius: 4px;
font-size: 16px;
}
.waitlist-form button {
width: 100%;
padding: 14px 24px;
background: #0073aa;
color: white;
border: none;
border-radius: 4px;
font-size: 16px;
cursor: pointer;
transition: background 0.3s;
}
.waitlist-form button:hover {
background: #005a87;
}Add form wrapper with class for styling
Wrap your form HTML in a container div to make styling easier:
<div class="waitlist-form">
<form action="https://waitlister.me/s/YOUR_WAITLIST_KEY" method="POST">
<!-- your form fields here -->
</form>
</div>Whitelist your WordPress domain
In Waitlister settings → Configure → Whitelisted domains, add your WordPress site domain:
Production: yourdomain.com
WWW version: www.yourdomain.com
For subdomain: blog.yourdomain.com
For localhost testing: localhostAdd to WooCommerce product pages (optional)
To add waitlist forms to out-of-stock WooCommerce products, paste your form code in the product description or use a shortcode plugin to embed it conditionally when products are out of stock.
Test thoroughly across devices
Test form submissions, check mobile responsiveness, verify emails arrive, and confirm data appears in Waitlister dashboard. Test in different browsers.

Quick fixes for WordPress-specific problems
Check that the Waitlister script was added correctly to footer.php or via a header/footer plugin. Also verify you're viewing the page on the front-end (not in the editor). Clear all WordPress caching plugins (WP Rocket, W3 Total Cache, etc.).
Verify your domain is whitelisted in Waitlister settings. Check both www and non-www versions. Also ensure your form action URL includes the correct waitlist key with no extra spaces or characters.
Use the "Custom HTML" block, not the "HTML" block (they're different). The Custom HTML block preserves all code. Alternatively, switch to the Code Editor view (three dots menu → Code Editor) and paste there.
Your theme CSS may be interfering. Add more specific CSS selectors, or use !important flags sparingly. Inspect the form with browser dev tools to see which theme styles are conflicting.
Adjust the data-height attribute in your embed code. Start with 450px and adjust up or down based on your form design.
Clear all caches: WordPress cache, page cache, browser cache, and CDN cache if applicable. In caching plugins, add an exception for the Waitlister script URL or disable JavaScript minification for it.
Ensure the Waitlister script is loaded globally (in footer.php or site-wide custom code), not just on specific pages. Elementor popups need scripts available across the entire site.
Verify each input has a unique "name" attribute. Any field name beyond email, name, and phone is automatically saved as custom data. Check for typos in field names.
Add mobile-specific CSS using media queries. Ensure input width is 100% and padding is touch-friendly (minimum 44px height for touch targets).
Waitlister doesn't use your WordPress database at all. If you're seeing database errors, they're unrelated to the waitlist integration. Check your WordPress error logs for the actual cause.
