FAQ

Common questions

What WooCommerce plugin does WA.Expert provide?

WA.Expert's WooCommerce plugin is available in the WordPress plugin directory. It provides a no-code interface for mapping WooCommerce order statuses to WA.Expert templates, abandoned cart detection, and bulk messaging to customers. For more customised setups — custom order statuses, custom fields, complex conditional logic — use the WordPress functions.php webhook approach shown in this guide.

How does abandoned cart recovery work technically in WooCommerce?

WooCommerce saves cart data per session and per user (for logged-in customers). The WA.Expert plugin checks every 10 minutes for carts older than your configured threshold (default: 30 minutes) that have not converted to an order. It cross-references the cart session with the customer's phone number (from billing data if they've registered) and triggers the recovery sequence. Anonymous carts without a saved phone number cannot be recovered.

Can I send WhatsApp messages for custom WooCommerce order statuses?

Yes — the webhook approach in functions.php supports any WooCommerce order status string, including custom statuses added by WooCommerce extensions. Replace 'processing' in the code example with your custom status slug. Multiple status triggers can be set in the same function with if/elseif logic, each mapping to a different WA.Expert template.
