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.

To check, go to WooCommerce → Settings → Emails and confirm email notifications are enabled. Open each email type and verify the toggle is on, recipient is correct, and email address “From” is valid. Next, place a test order using a low-cost product or a test payment method. Check whether the customer and admin received emails. Also review your order status, because WooCommerce triggers emails by status changes, like Pending to Processing. Check spam and promotions tabs too. If emails fail, install an SMTP plugin, test sending, and check your hosting mail logs.

To automatically print WooCommerce orders, you need a plugin like Print Invoice & Delivery Notes for WooCommerce or Auto Print Orders. First, install and activate your chosen plugin via Plugins > Add New in your WordPress dashboard. Then configure it by selecting the printer, print format (invoice, packing slip, etc.), and triggering events—such as new orders or order status changes. Some plugins allow direct integration with Google Cloud Print or other print services. This setup enables seamless, automatic printing without manual steps. It’s ideal for physical stores or warehouses to streamline order fulfillment and improve efficiency in order processing.

For UPS shipping in WooCommerce, the official UPS Shipping Method extension from WooCommerce provides real‑time UPS rates at checkout based on address, weight, and shipping services. It’s reliable if you just need live UPS pricing. For more comprehensive features like label printing and tracking, plugins such as PluginHive’s UPS Shipping Plugin or ShipEngine/EasyPost integrations let you fetch UPS rates and handle label creation directly in your dashboard. Another versatile choice is a multi‑carrier shipping plugin that includes UPS alongside other carriers, giving flexibility and automation for shipping logistics.

There isn’t a separate “WooCommerce payments plugin” just for hotel bookings. You normally use a hotel booking/booking calendar plugin that creates bookable products, and then accept payments through any standard WooCommerce gateway. Popular booking options include WooCommerce Bookings (paid) or free hotel booking plugins that integrate with WooCommerce. For payments, use WooPayments, Stripe, PayPal, Square, Razorpay, or any gateway your region supports. If you need deposits or partial payments, add a deposits plugin or choose a booking plugin that supports pay-later and deposit rules. This setup keeps booking and payments flexible. Confirm refunds, cancellation fees, and tax settings match policies.
