To integrate an SMS API in WordPress WooCommerce, first choose an SMS provider (Twilio, MSG91, Textlocal, Plivo, etc.) and get API keys, sender ID, and templates. The easiest method is a plugin. Install an SMS plugin that supports WooCommerce events like new order, processing, completed, failed, and OTP. Add your API credentials in the plugin settings and map templates for customer and admin messages. If you prefer custom code, use WooCommerce hooks like woocommerce_order_status_changed to trigger an API request with order data (name, order ID, amount). Test in sandbox, verify delivery reports, then enable live mode.

The WooCommerce checkout is the final step where customers complete their purchase. It collects billing details, shipping information, and payment method. After reviewing the order, the customer places it. WooCommerce then processes payment through the selected gateway, creates the order, reduces stock, and sends confirmation emails. A smooth checkout experience helps reduce cart abandonment and improves sales.

To add products to a WooCommerce page, first ensure that you have created the product(s). Next, edit the page you want to add the products to. Use the WooCommerce block editor or shortcodes to display products. For example, you can use the [products] shortcode to display a grid of products or the [product id="product_id"] shortcode for a single product. You can also manually select products from the product blocks or widgets within the page builder interface.

Catalog mode in WooCommerce is a setup where your store works like a product showcase instead of a shopping store. Customers can view products, categories, images, and descriptions, but they cannot add items to cart or complete checkout. Many store owners use catalog mode for wholesale inquiries, out-of-stock periods, B2B pricing requests, or pre-launch product displays. In catalog mode, you can hide prices, disable the cart and checkout pages, and replace Add to Cart with custom buttons like “Call Now,” “Get Quote,” or “Contact Us.” It helps you generate leads while still showing products professionally.
