<h2 style="text-align: left">Create shipping labels for USPS the smart way </h2>
With the <a href="http://stamps.com/woocommerce">Stamps.com</a> integration, you can automatically create ready-to-print shipping labels for USPS®, UPS®, and more carriers based on items in an order. Stamps.com seamlessly accesses the latest USPS rates when creating your labels, giving you unprecedented reliability, ease, and speed.
This extension does not display shipping rates to your customers during the checkout process. If you want USPS rates shown on the cart/checkout pages of your site, you need to purchase the <a href="https://woocommerce.com/products/usps-shipping-method/">USPS Shipping Methods</a> extension as well. Using these two extensions together, your customers see the best rates during checkout and you take advantage of those same rates when creating shipping labels via the backend order admin.

WooCommerce Stamps.com API

With the Stamps.com integration you can automatically create ready-to-print shipping labels for USPS, based on items in an order.

easycouriercy

Run your entire courier workflow from the WooCommerce Orders screen. easyCourier for WooCommerce links your shop to your easyCourier account so you can dispatch orders, print waybills and labels, and follow each parcel to the customer’s door — without copying addresses into a separate courier portal or re-keying order details by hand.
Fewer manual steps mean fewer mistyped addresses, faster dispatch, and a clearer picture of where every order stands.
<h4>What you can do</h4>
<ul>
<li>Send orders to the courier in one click — dispatch any order straight from the Orders screen, or let the plugin do it automatically when an order reaches a status you choose.</li>
<li>Print waybills and labels — generate waybills and shipping labels for a single order or in bulk for the whole day’s dispatch.</li>
<li>Track every delivery in place — see live delivery status right on the order page, and cancel a scheduled pickup if plans change.</li>
<li>Manage multiple pickup locations — add as many pickup points as you need across Cyprus and Greece.</li>
<li>Control delivery options per order — choose the delivery type, package size, and available pickup time slot that fit each shipment.</li>
<li>Close the loop automatically — optionally mark orders complete the moment the courier confirms delivery.</li>
</ul>
<h3>External services</h3>
This plugin relies on a third-party service operated by Svelta Ltd (https://www.svelta.io), accessed through its API at https://api.svelta.io. Svelta is the delivery platform that powers your easyCourier account, and every connection, settings change, pickup-location update, and order action performed through this plugin sends data to Svelta. The service is required for the plugin to function — without it, deliveries cannot be created, waybills cannot be printed, and delivery status cannot be tracked.
Data sent and when
<ul>
<li>Store connection: when you click Connect, your site URL and a return URL pointing back to your WordPress admin are sent to the Svelta API to initiate the connection flow. The browser is then redirected to the Svelta Portal (https://portal.svelta.io) where you complete account setup. On return, a one-time flow token is exchanged server-to-server for your API credentials.</li>
<li>Store disconnection: when you click Disconnect (or deactivate the plugin while connected), your site URL is sent so the integration is removed from your easyCourier account.</li>
<li>Settings sync: when you save plugin settings, your site URL and chosen options are sent — order creation mode, trigger order status, delivery type, default package size, single-package flag, and auto-complete flag.</li>
<li>Pickup locations: when you add, edit, or remove a pickup location, its name, street, number, postcode, country, and optional building/floor/flat details are sent. For locations in Greece the geocoded latitude and longitude are also sent. Address autocomplete sends the typed search text or postcode only; for Greek locations a follow-up call sends the identifier of the suggestion you pick to retrieve its full address.</li>
<li>Creating a delivery: when an order is dispatched to the courier, the order ID, customer note, billing phone, the full shipping details (first name, last name, company, address lines, postcode, phone), line items (id, name, quantity), the selected pickup location, and the order’s meta data are sent.</li>
<li>Printing a waybill / label: the tracking IDs returned when the delivery was created are sent so a waybill/label PDF can be generated and downloaded.</li>
<li>Tracking status: the order ID is sent to retrieve the current delivery status displayed on the order page.</li>
<li>Cancelling a delivery: the tracking ID is sent to cancel a pickup.</li>
<li>Pickup slots: the pickup store ID is sent to retrieve the available time slots shown on the order page.</li>
<li>Available delivery types: the pickup postcode, customer postcode, country, selected pickup time, and chosen package sizes are sent to retrieve the delivery options and prices available for that route.</li>
<li>Reference data (delivery types and package sizes): when the Settings page or the manual-delivery dialog loads, the plugin requests the list of delivery-type presets and package-size presets so the dropdowns can be populated. These requests carry only your API key — no order, customer, or store data is sent.</li>
</ul>
