How to Develop WordPress Integrations with Third-Party Services

Step 1: Identify the Required Integration

Determine the service you need to integrate (e.g., PayPal, Google Analytics).
Check if a pre-built plugin is available or if custom development is needed.

Step 2: Use Plugins for Quick Integration

Many services offer official WordPress plugins. Examples:

WooCommerce Stripe Gateway – For Stripe payments.
MonsterInsights – For Google Analytics.
Zapier for WordPress – For workflow automation.

📌 Best Practice: Always use well-reviewed and frequently updated plugins.

Step 3: Develop Custom API Integrations

If no plugin is available, you may need a custom API integration.

Example: Fetching data from a REST API in WordPress

function fetch_third_party_data() {
    $response = wp_remote_get('https://api.example.com/data');
    
    if (is_wp_error($response)) {
        return 'Error fetching data';
    }

    $data = wp_remote_retrieve_body($response);
    return json_decode($data, true);
}

🔹 Use Case: Fetching real-time product data from an external API.

Step 4: Implement Webhooks for Real-Time Syncing

Some services offer webhooks for automatic updates.

Example: Listening to a webhook from Stripe for new payments

add_action('wp_ajax_handle_webhook', 'process_webhook');
function process_webhook() {
    $payload = file_get_contents('php://input');
    $event = json_decode($payload, true);

    if ($event['type'] == 'payment_intent.succeeded') {
        // Process successful payment
    }
    wp_die();
}

🔹 Use Case: Updating WordPress order status after a successful Stripe payment.
