PayPal: Can you get the IP address of the client (buyer) via IPN/PDT?

Question

I never found such a feature on Paypal's website. I want to get the address via IPN/PDT. Alternatives outside PayPal are useless to me, I already have those. Thanks for resp.

Answer 1

PayPal in the foreseeable future due to unknown reasons does not allow this feature. Probably the best solution is to send parameter CUSTOM and enter the necessary data into it, they are sent to PayPal and then back to the merchant's site. Payment order must be dispatched from the merchant's site, differently detect IP addresses will not be correct. Details here.

CUSTOM parameter is limited up to 256 characters.

Send via GET method

https://www.paypal.com/cgi-bin/webscr?cmd=_s-xclick&hosted_button_id=XY&custom=custom_string

Send via POST method

<input type="hidden" name="custom" value="custom_string" /> 

Callback data

Callback is performed via NOTIFY_URL parameter. To the specified URL will be sent details of the transaction. NOTIFY_URL must be included in the configuration Buy Now button or URL link or default in the PayPal account.

Example URL link:

https://www.paypal.com/cgi-bin/webscr?cmd=_s-xclick&hosted_button_id=XY&custom=custom_string&notify_url=http://site.com/pay.php

Data getting was performed via GET or POST method from PayPal site with array $keyarray['custom'] (default). See details here.
