wapipro

WapiPro for WooCommerce connects a WooCommerce store to the WapiPro service. Store administrators can sync checkout customers to a WapiPro audience and trigger approved WhatsApp templates when WooCommerce order statuses change.
This plugin requires a WapiPro account and API token. The service is available at https://wapipro.com.
<h4>External service disclosure</h4>
This plugin communicates with WapiPro only after a store administrator adds a WapiPro API token or uses a WapiPro action such as checking the connection, creating an audience, creating a template, syncing an opted-in checkout customer, or sending an order notification.
Data sent to WapiPro may include:
<ul>
<li>Store domain and plugin metadata.</li>
<li>WapiPro audience name or audience ID.</li>
<li>Customer billing phone number, billing country, first name, and last name.</li>
<li>Order ID, order number, total, currency, status, order URL, billing city/country, shipping city/country, and optional tracking URL supplied by another plugin through the <code>wapipro_wc_tracking_url</code> filter.</li>
<li>Checkout WhatsApp consent status, consent source, and consent timestamp.</li>
<li>WhatsApp template name, language, and template variables needed to send the message.</li>
</ul>
Customer contact sync and order notifications are gated by the checkout consent checkbox. The checkbox is unchecked by default.

The most flexible and complete solution for your WooCommerce webshop to customize your order numbers!
By default, WooCommerce uses the WordPress post ID of the order, which result in gaps between the order numbers. With this plugin you can configure the order numbers to have consecutive counters. Furthermore, the order number can contain the year, and the counter can be configured to reset each year.
The number format is a simple string, where # indicates the counter. 
To get order numbers like “WC-376”, “WC-377”, “WC-378”, etc., simply set the format to “WC-#”.
The plugin comes in two flavors:
<ul>
<li>This free basic version, which provides sequential numbers and allows arbitrary text (prefix / postfix) in the numbers</li>
<li>The paid advanced version, with lots of additional features:
<ul>
<li>Counter formatting: initial value, counter increments, number padding</li>
<li>Flexible counter resets</li>
<li>Lots of variables to be used in the formats
<ul>
<li>date/time: year, month, day, hour, etc.</li>
<li>address: customer country, zip, name, etc.</li>
<li>order-specific: Number of articles, products, order total etc.</li>
<li>product categories, shipping method</li>
</ul>
</li>
<li>Custom variable definitions (with conditions on available variables)</li>
<li>Multiple concurrent counters (e.g. numbering per country, per day, per ZIP, …)</li>
<li>Different order numbers for free orders (e.g. “FREE-01” for free orders)</li>
<li>Different number format for e.g. certain IP addresses (for testing)</li>
<li>Different number format depending on products, product categories, shipping classes</li>
<li>Customize invoice numbers (only for the “WooCommerce PDF Invoices and Package Slips” plugin)</li>
<li>Different numbers depending on vendors (WC Product Vendors, WC Vendors and YITH WC Multi Vendor plugins)</li>
</ul>
</li>
</ul>
