As I work on creating a website for online purchases, I have a question about integrating PayPal. Is there a method to verify payment received in PayPal and trigger certain code functions afterward? Or would it be better to include a PayPal widget that automatically executes the necessary code upon completion of payment? The entire process is being built using HTML and CSS as it's a website project.
Check out the information on Instant Payment Notification (IPN). Whenever a transaction occurs in your PayPal account, their server will send the transaction data to a URL that you specify using the POST method. Your script will then receive this data, verify it with PayPal to confirm its authenticity, and allow you to process the information according to your needs.
This feature provides you with the capability to update your own database, send email notifications, interact with third-party web services, or perform any other automated tasks when transactions are received in your account. It is effective for handling payments, refunds, disputes, and more, enabling you to streamline various processes. Additionally, this system operates in real-time, offering immediate functionality.
