How do WhatsApp back-in-stock alerts work?

When a product goes out of stock, customers can opt in for notifications. Once the item is restocked, WhatsBizAPI automatically sends a WhatsApp message to all waitlisted customers with product details, price, and a direct purchase link. The 98% open rate ensures customers see the alert immediately.

Can I automate back-in-stock notifications from my e-commerce store?

Yes. WhatsBizAPI integrates with Shopify, WooCommerce, and other platforms via API and webhooks. When inventory levels change from zero to available, the system automatically triggers WhatsApp notifications to customers who registered interest in that product.

What is the conversion rate for back-in-stock WhatsApp alerts?

WhatsApp back-in-stock alerts typically achieve 10-15% conversion rates compared to 2-3% for email alerts. The combination of instant delivery, high open rates (98%), and direct CTA buttons makes WhatsApp the most effective channel for restock notifications.

Can I send price drop alerts via WhatsApp?

Yes. WhatsBizAPI supports price drop notification templates. When a product price is reduced, you can notify customers who viewed or wishlisted that product. These are classified as marketing templates by Meta and require customer opt-in.

How do I set up a WhatsApp waitlist for out-of-stock products?

Add a 'Notify Me on WhatsApp' button on your product pages. When clicked, collect the customer's WhatsApp number and product preference. WhatsBizAPI stores this data and automatically sends a restock alert when inventory is updated. Integration takes less than 30 minutes with our API documentation.
