Common Patterns

Below are real-world implementation examples showing how to combine these hooks.

Adding a Custom Tool

Register a tool in the SLSWC Settings > Tools tab and handle its execution. Clicking the button sends POST /wp-json/slswc/v1/settings/tools/{tool_id} (requires manage_options), which calls the registered callable and then fires slswc_tools_process_{tool_id}:

// Register the callable that runs the tool.
add_filter( 'slswc_server_tools', function ( $tools ) {
    $tools['reset_staging_activations'] = 'my_reset_staging_activations';
    return $tools;
} );

// Add the button to the Tools tab, before the closing sectionend field.
add_filter( 'slswc_tools_settings', function ( $settings ) {
    $button = array(
        'title' => __( 'Reset Staging Activations', 'my-extension' ),
        'desc'  => __( 'Clear all staging domain activations across all licenses.', 'my-extension' ),
        'id'    => 'reset_staging_activations',
        'type'  => 'tool-button',
    );
    array_splice( $settings, count( $settings ) - 1, 0, array( $button ) );
    return $settings;
} );

function my_reset_staging_activations() {
    // Your logic to reset staging activations...
}

// Optional: run follow-up work after the tool's callable.
add_action( 'slswc_tools_process_reset_staging_activations', function ( $tools ) {
    // Your follow-up logic...
} );

Filtering License Activation Results

Modify the response returned when a license is activated — for example, to include custom metadata:

add_filter( 'slswc_activate_result', function ( $result ) {
    // Add a custom field to the activation response.
    $result['support_url'] = 'https://your-store.com/support/';
    $result['docs_url']    = 'https://your-store.com/docs/';
    return $result;
} );

Custom DRM Configuration

Override DRM settings for a specific product from outside the product's own code — useful for a site-wide licensing extension:

add_filter( 'slswc_drm_config_my-plugin', function ( $config ) {
    // Give customers a more generous grace period.
    $config['grace_soft_days'] = 5;
    $config['grace_lock_days'] = 14;

    // Customize the purchase URL for a seasonal promotion.
    $config['purchase_url'] = 'https://your-store.com/black-friday/';

    return $config;
} );

Tip: The {identifier} in DRM filter names is typically the product's text domain. See the DRM docs for the full list of configuration options.

Hooking Into Support Ticket Events

Send a Slack notification when a support ticket is created or assigned:

add_action( 'slswc_support_ticket_created_admin', function ( $ticket ) {
    wp_remote_post( 'https://hooks.slack.com/services/YOUR/WEBHOOK/URL', array(
        'body' => wp_json_encode( array(
            'text' => sprintf( 'New support ticket: %s', $ticket->title ),
        ) ),
        'headers' => array( 'Content-Type' => 'application/json' ),
    ) );
} );

add_action( 'slswc_support_ticket_assigned', function ( $ticket, $agent_id ) {
    $agent = get_userdata( $agent_id );
    // Notify the agent via your preferred channel...
}, 10, 2 );

Customizing Client Library API Requests

Add custom headers or increase the timeout for license server requests:

add_filter( 'slswc_request_options_my-plugin', function ( $options ) {
    $options['timeout'] = 60;
    $options['headers'] = array(
        'X-Custom-Header' => 'my-value',
    );
    return $options;
} );
