<p><strong>msgflash</strong> connects your WooCommerce store to WhatsApp, enabling automated, real-time customer messaging without manual effort.</p>
<p>Whether you run a boutique or a high-volume store, msgflash keeps your customers informed and engaged through the channel they use every day.</p>
<h4>Key Features</h4>
<ul>
<li><strong>Order Confirmations</strong> – Automatically send a WhatsApp message when a customer places an order.</li>
<li><strong>Shipping Notifications</strong> – Notify customers the moment their order status changes to completed/shipped.</li>
<li><strong>Abandoned Cart Recovery</strong> – Send reminders to customers who left items in their cart without completing their purchase.</li>
<li><strong>Customizable Templates</strong> – Personalize every message with variables like <code>{first_name}</code>, <code>{order_id}</code>, <code>{order_total}</code>, and more.</li>
<li><strong>Async Processing</strong> – Messages are sent in the background so your checkout page never slows down.</li>
<li><strong>Phone Number Normalization</strong> – Automatically formats phone numbers to international standards.</li>
<li><strong>Multi-Instance Support</strong> – Choose which WhatsApp instance to use from your MsgFlash account.</li>
</ul>
<h4>Use Cases (2026 Patterns)</h4>
<ol>
<li><strong>Récupération de Paniers (Cart Recovery)</strong> – Reduce abandoned carts by automatically reaching out to customers who didn’t complete checkout. Set a configurable delay (30 min to 24 hours).</li>
<li><strong>Notifications Transactionnelles (Transactional Notifications)</strong> – Keep customers informed at every step: order received, order shipped, with tracking URLs.</li>
<li><strong>Suivi de Colis (Package Tracking)</strong> – Include shipping method and tracking links directly in WhatsApp messages.</li>
</ol>
<h4>How It Works</h4>
<ol>
<li>Create an account on <a href="https://msgflash.com" rel="nofollow ugc">msgflash.com</a> and connect a WhatsApp instance.</li>
<li>Install the plugin and paste your API key.</li>
<li>Select your default WhatsApp instance.</li>
<li>Enable the automations you want and customize your message templates.</li>
<li>That’s it — msgflash handles the rest automatically.</li>
</ol>
<h4>Requirements</h4>
<ul>
<li>WordPress 5.8 or higher</li>
<li>PHP 7.4 or higher</li>
<li>WooCommerce 5.0 or higher</li>
<li>An active MsgFlash account with at least one connected WhatsApp instance</li>
</ul>
<h4>Important Notes</h4>
<ul>
<li>The plugin requires a valid MsgFlash API key (<code>msgf_live_...</code>).</li>
<li>You must have at least one connected WhatsApp instance in your MsgFlash account.</li>
<li>Phone numbers should be valid and in international format for reliable delivery.</li>
</ul>
<h3>External services</h3>
<p>This plugin connects to the MsgFlash API, provided by MsgFlash, to send WhatsApp messages and retrieve WhatsApp instance information for your WooCommerce store.</p>
<p>The MsgFlash API is required for the plugin to work. It is used to test the API connection, fetch the WhatsApp instances connected to your MsgFlash account, and send configured WooCommerce messages such as order confirmations, shipping notifications, abandoned cart recovery messages, and test messages.</p>
<p>The plugin may send the following data to the MsgFlash API when an enabled automation runs or when the store administrator tests the connection or sends a test message:</p>
<ul>
<li>MsgFlash API key configured by the site administrator</li>
<li>WooCommerce order information required to build the message, such as order ID, order status, order total, billing first name, billing phone number, shipping method, tracking URL if configured, and related message template variables</li>
<li>Customer phone number used as the WhatsApp recipient</li>
<li>Message content generated from the configured template</li>
<li>Selected MsgFlash WhatsApp instance identifier</li>
<li>Store/plugin metadata required for API processing and troubleshooting</li>
</ul>
<p>This data is sent only when the plugin needs to communicate with the MsgFlash API, for example when testing the connection, retrieving available instances, sending a test message, or sending an enabled WooCommerce notification.</p>

<h4>Privacy & GDPR</h4>
<p>This plugin sends WhatsApp messages using customer data already stored in WooCommerce (phone number, name, order details). No additional personal data is collected or transmitted to third-party services beyond the MsgFlash API required for message delivery.</p>

<p>Have you ever seen an error log like the one below?</p>
<blockquote>
<p>PHP Fatal error: Allowed memory size of xxxxxx bytes exhausted (tried to allocate xxx bytes) in /var/www/wordpress/wp-includes/wp-db.php on line 2007</p>
</blockquote>
<p>This means that <a href="https://www.php.net/manual/en/ini.core.php#ini.memory-limit" rel="nofollow ugc">PHP memory limit</a> is exhausted while retrieving data from a database. In any case, this happens when your site has big data and makes insane loops inside.</p>
<p>But we want to know that <strong>which plugin tried to retrieve data?</strong></p>
<p>Hagakure adds extra information to error.log file when <code>wp-db.php</code> causes memory limit error:</p>
<pre>[08-May-2019 10:28:37 UTC] wpdb Error Backtrace:

<p>This log will always follow the memory limit Fatal Error by <code>wp-db.php</code>. Now you can find <code>#8</code> calls <code>get_posts</code> repeatedly.</p>
<p>We recommend watching logs with notification services like <a href="https://docs.aws.amazon.com/AmazonCloudWatch/latest/logs/WhatIsCloudWatchLogs.html" rel="nofollow ugc">CloudWatch Logs</a>.<br />
This error occurs in the productional environment, and you may not have a chance to see it occurs.<br />
We use Hagakure with our <a href="https://hosting.kunoichiwp.com/" rel="nofollow ugc">hosting service</a>, please look forward to seeing <a href="https://kunoichiwp.com/blog" rel="nofollow ugc">our blog published</a> and describing the integration!</p>
<p>This plugin also adds debug backtrace to error logs. To modify the error level to a detailed backtrace, define the constant in <code>wp-config.php</code> or somewhere else:</p>
<pre>define( 'HAGAKURE_ERROR_LEVEL', E_NOTICE | E_USER_WARNING | E_WARNING | E_USER_ERROR );</pre>
<p>Besides that, if <code>SAVEQUERIES</code> is set <code>true</code>, the slow query log will be logged with PHP debug backtrace. This helps you to debug.</p>
