Short description

Create a professional addon that checks for WPForms, adds settings (API URL/key), listens to form submissions, sends data to an endpoint/Slack/SMS provider, logs results, and includes readme + test checklist.

Steps

1. Define the sync destination (API/Slack).
2. Implement settings + submission hook.
3. Add logging and failure handling.
4. Document and test on staging.

Final project scope

1. Plugin bootstrap + WPForms dependency check
2. Settings page for API credentials
3. Form selector (which forms to sync)
4. wpforms_process_complete handler
5. wp_remote_post with timeout + error logging
6. Admin notice on missing WPForms
7. Basic success/failure entry note/log
8. readme.txt + changelog
9. Staging test checklist

Starter bootstrap

<?php
/**
 * Plugin Name: Acme WPForms Sync
 * Description: Final project — sync WPForms entries to an API.
 * Version: 1.0.0
 * Text Domain: acme-wpforms-sync
 */

if (! defined('ABSPATH')) {
    exit;
}

add_action('plugins_loaded', function () {
    if (! function_exists('wpforms')) {
        add_action('admin_notices', function () {
            echo '<div class="notice notice-error"><p>Acme WPForms Sync requires WPForms.</p></div>';
        });
        return;
    }
    require_once __DIR__ . '/includes/class-acme-wpforms-sync.php';
    AcmeWPFormsSyncPlugin::instance(__FILE__)->boot();
});
