How to integrate
Follow these Shopify-specific instructions
Get your Waitlister endpoint
Login to Waitlister → Overview → copy your waitlist key. Your form action URL is:https://waitlister.me/s/YOUR_WAITLIST_KEY
Decide on implementation location
Choose where to add waitlist functionality:
• Product pages (for out-of-stock or coming-soon products)
• Collection pages (for entire collection launches)
• Dedicated landing pages (for pre-launch campaigns)
• Cart page (for abandoned cart capture)
Edit your product page template
In Shopify admin → Online Store → Themes → Actions → Edit code. Open Sections/main-product.liquid or Templates/product.liquid. Add this form where you want it to appear:
{% if product.available == false %}
<div class="product-waitlist">
<h3>Get notified when back in stock</h3>
<form action="https://waitlister.me/s/YOUR_WAITLIST_KEY" method="POST">
<input type="email" name="email" placeholder="Your email" required>
<input type="hidden" name="product" value="{{ product.title }}">
<button type="submit">Notify Me</button>
</form>
</div>
{% endif %}Add product context (optional but recommended)
Pass product details to Waitlister using hidden fields. This helps you know which products customers want:
<input type="hidden" name="product_title" value="{{ product.title }}">
<input type="hidden" name="product_id" value="{{ product.id }}">
<input type="hidden" name="variant" value="{{ product.selected_or_first_available_variant.title }}">
<input type="hidden" name="product_url" value="{{ shop.url }}{{ product.url }}">Style the form to match your theme
Add CSS to your theme's stylesheet. In theme editor, find Assets/theme.scss.liquid or Assets/style.css and add:
.product-waitlist {
margin: 30px 0;
padding: 25px;
background: #f8f8f8;
border-radius: 8px;
}
.product-waitlist h3 {
margin-bottom: 15px;
font-size: 18px;
font-weight: 600;
}
.product-waitlist input[type="email"] {
width: 100%;
padding: 12px 16px;
margin-bottom: 12px;
border: 1px solid #ddd;
border-radius: 4px;
font-size: 14px;
}
.product-waitlist button {
width: 100%;
padding: 14px 24px;
background: #000;
color: #fff;
border: none;
border-radius: 4px;
font-size: 14px;
font-weight: 600;
cursor: pointer;
transition: opacity 0.3s;
}
.product-waitlist button:hover {
opacity: 0.8;
}Whitelist your Shopify domain
In Waitlister → Settings → Configure → Whitelisted domains, add:
Your store: yourstore.myshopify.com
Custom domain: yourdomain.com
Add both if you use a custom domainTest with out-of-stock products
Set a product to out-of-stock in your Shopify admin. View the product page and verify the waitlist form appears. Submit a test signup and check Waitlister dashboard.
Set up customer notifications
When products are restocked, export the waitlist from Waitlister and send notification emails through Shopify Email, Klaviyo, or your email tool. Include product links and purchase CTAs.

Quick fixes for Shopify-specific problems
Check that the Waitlister script is in theme.liquid before </body> tag. Also verify you're viewing a product that matches your Liquid conditions (e.g., if you used {% if product.available == false %}, the product must be out of stock).
Verify both your myshopify.com domain AND custom domain (if you have one) are whitelisted in Waitlister settings. Check form action URL has correct waitlist key with no extra spaces.
Theme updates can overwrite customizations. Always duplicate your theme before updating. After updates, re-add the Waitlister script and form code to the new theme version.
Your theme CSS may be interfering. Add more specific CSS selectors or use !important flags. Inspect the form with browser DevTools to identify conflicting styles.
Check your Liquid conditional statement. It should be {% if product.available == false %} to only show when out of stock. The double equals is important!
Make sure hidden input fields have correct Liquid variable syntax. Check spelling of {{ product.title }}, {{ product.id }}, etc. View page source to verify values are populated.
Ensure the Waitlister script is in theme.liquid (not in a specific section). Scripts in theme.liquid load on all pages including mobile app views.
If showing multiple product variants with separate forms, ensure each form has unique identifiers or use JavaScript to handle submissions. Consider using a single form with variant dropdown instead.
Add mobile-specific CSS using media queries. Ensure input fields are full-width and buttons are touch-friendly (minimum 44px height).
Common questions
About Shopify integration
Yes, for most stores. Waitlister has no monthly fees (apps charge $10-30/month), works with any theme without conflicts, and gives you full control over your customer data with CSV export. Plus, you avoid adding another app to your Shopify stack.
Absolutely! Each product can have its own waitlist by using different waitlist keys, or use the same key and track products via hidden fields. Your choice based on how you want to organize notifications.
Export your waitlist from Waitlister to CSV, then upload to Shopify Email, Klaviyo, Mailchimp, or any email tool. Send a targeted campaign with product links and purchase CTAs. Many store owners see 30-40% conversion rates.
The waitlist forms are for online store only. However, you can use the same customer data for in-store marketing and notify customers when products arrive at retail locations.
Yes! Perfect for pre-orders. Create a product marked as "coming soon", add the waitlist form, and collect interest. When ready to launch, notify all waitlist members with purchase links. Many stores use this to validate demand before manufacturing.
Yes, but requires custom Liquid code. You can show waitlist forms for specific out-of-stock variants while hiding them for available variants. Pass variant information through hidden fields to track which variants customers want.
Waitlister captures all customer emails regardless of location. When notifying, you can segment by country using additional custom fields (add a country selector to your form) or use Shopify Markets data.
Yes! Export your waitlist data from Waitlister to CSV, then import into any email platform. You can also use Waitlister's webhook feature to automatically sync new signups to your email tool (webhook URL needed).
The waitlist stays active until you manually notify customers and clear it. Best practice: Export the list, send restock notifications via email, then archive or clear the waitlist in Waitlister dashboard.
Yes! In Waitlister dashboard, go to Settings → Configure → Thank You Page. Customize the message or redirect users to a custom success page on your store for a branded experience.
Yes! Works perfectly with Shopify Plus stores. You have even more flexibility with Plus features like custom checkout, Scripts, and Flow for automation.
Not built-in, but you can manually close a waitlist by removing the form code when you hit your target. For automatic limits, you'd need custom JavaScript or use Waitlister API to check count before showing form.
