PayPal doesn't send me all fields to return url

Question

I've setup subscribe form for PayPal.

...
<input type="hidden" name="return" value="http://mysite.com/success/"&gt;
<input type="hidden" name="rm" value="2">
...

Then I make a payment in PP Sandbox and click to "Return to Merchant" button.

I expect:

all transaction data in $_POST, such txn_type and so on

I get:

[merchantReturn_x] => Return To Merchant
[auth] =>qQJeJB06AAvD3o1Q5_7MOb6oCrg7OLBbQnYJOLBn0x4xAjnRwG4wORijts5Bo5gYPGMAid1eC3R9m9FYDD2
[form_charset] => UTF-8

Whats wrong?

Answer 1

those data will not be posterd to that URL ... search the manual for IPN ( Instant Payment Notification ). Basicly there is another script that receives those parameters.

Answer 2

Untrue. The return value also gets all the transaction data. I am trying to figure it out myself as we speak, but I used to have an integration where all the transaction data was posted to both the IPN and the thank you page.

Answer 3

Did you find the answer to this problem?

I have the same problem with the paypal plugin for Omni-Site-Security membership system where the plugin is expecting _POST data to be returned to the return_url.
