What is the PRIMARY reason to utilize webhooks within a PayPal integration?

The primary reason to utilize webhooks within a PayPal integration is to receive real-time, push-based notifications of events occurring within your PayPal account, eliminating the need for constant polling of the PayPal API. Webhooks allow PayPal to automatically send data to your server whenever a specific event occurs, such as a payment being completed, a refund being issued, or a subscription being created. This enables your application to react immediately to these events without having to repeatedly check the PayPal API for updates. For example, when a payment is completed, PayPal can instantly send a webhook notification to your server, triggering actions such as updating your order database, sending a confirmation email to the customer, and initiating the fulfillment process. This real-time notification mechanism improves efficiency, reduces server load, and ensures that your application stays synchronized with the latest PayPal transaction data. It enables event-driven architecture, reducing latency and improving responsiveness compared to traditional polling methods. Polling requires your system to constantly ask PayPal for updates, whereas webhooks have PayPal notify your system when something happens.
