There are two way to check donor made donation:

1) used "notify_url" parameter (safe)

2) used "return" parameter ( unsafe)

Code example:

When some one made donation donor automatically redirect to return url but this option is not safe because may be some one direct open this url.

best way to know donor made donation choose paypal notify_url parameter.

PayPal will send post request to notify_url.
