<h3>🧩 Shortcodes</h3>
<p>The plugin provides shortcodes to integrate SMS features into your frontend.</p>
<h4>📝 Common Attributes</h4>
<ul>
<li>action: (required) One of signup, update, unsubscribe, send_sms.</li>
<li>recaptcha: Set to 1 to enable Google reCAPTCHA (must be configured in settings).</li>
<li>embed_css: Set to 1 to embed basic styling for the form.</li>
<li>groups: Comma-separated list of group/tag IDs to target.</li>
<li>allowed_countries: Comma-separated list of country codes (e.g., 45,44).</li>
</ul>
<h4>➕ Signup Form</h4>
<p>[gatewayapi action=”signup” groups=”1,2,3″]</p>
<h4>🔄 Update Profile</h4>
<p>[gatewayapi action=”update”]</p>
<h4>❌ Unsubscribe</h4>
<p>[gatewayapi action=”unsubscribe”]</p>
<h4>✉️ Send SMS</h4>
<p>[gatewayapi action=”send_sms” groups=”1″]</p>
<p>Security Warning: The send_sms action allows sending SMS messages from your frontend. This can be dangerous if left open to the public as it could be abused to send spam or drain your GatewayAPI credits.</p>
<p>We strongly recommend combining this with a security system, such as:<br />
* Placing the shortcode on a password-protected page.<br />
* Restricting access to specific user roles using a membership plugin.<br />
* Always enabling recaptcha=”1″ to prevent automated abuse.</p>
<h3>❓ Frequently Asked Questions</h3>
<h4>Can this plugin handle very large SMS campaigns?</h4>
<p>Yes. Campaigns are processed using Action Scheduler, ensuring stable delivery, high throughput, and retries — even on shared hosting environments.</p>
<h4>Does this plugin support personalized SMS messages?</h4>
<p>Yes. You can use dynamic placeholders from contacts and WooCommerce orders to send fully personalized, mail-merged SMS messages.</p>
<h4>Is WooCommerce required?</h4>
<p>WooCommerce is only required for order-based SMS notifications.<br />
Campaign messaging and contact management work without WooCommerce.</p>
<h3>🔗 External services</h3>
<p>This plugin connects to the GatewayAPI.com service to send SMS messages. This external service is required for the plugin’s primary functionality, which is delivering transactional and campaign SMS messages.</p>
<p>When sending an SMS, the plugin transmits the recipient phone number, message content, and related metadata (such as sender ID) to GatewayAPI.com. For WooCommerce notifications, order-related data may be used to generate the message content before it is sent.</p>
<p>No data is sent to GatewayAPI.com unless an SMS is actively being sent by the site administrator or triggered by configured WooCommerce events.</p>
<p>This service is provided by GatewayAPI ApS.</p>
<p>Privacy policy, terms and conditions, data processing agreement, and security certifications (including ISAE 3000 and ISAE 3402) are available at:<br />
