[quote author="Ji31" date="1185936358"]I need to send the id of post it is paid for and the contact address (not necessary the same as for payment was used for...)..[/quote] do you mean, you want know how to pass data via ipn to paypal and back, so you know later for which reason the money is for? like the id of the shopping cart or something like that?

you could use

Code:

$this->paypal_lib->add_field('custom', $your_shopping_cart_id);

//or

$this->paypal_lib->add_field('notify_url', site_url('paypal/ipn/'.$your_shopping_cart_id));

to pass data to the ipn function...
