Pass custom data to Paypal IPN
November 13, 2007, 03:21:30 pm
Hi,

I want to know if there's a way to send custom data to Paypal to get after with Paypal IPN. I need for example send a var like DON01, that will indicate our custom software that this is a donation from campaign number 1.

Or maybe it's still sending an id or something?

Thanks.
Leandro

There is no way to send in values programmatically. You can hack the code to do the needful. The relevant file is here:

http://fisheye.civicrm.org/browse/CiviCRM/branches/v1.9/CRM/Core/Payment/PayPalImpl.php?r=11314

line 521

Great.

Two more things:
1.- how can I know which donation is in that file? ($params['contributionID'] ?)
2.- Can I add more params and these are sent to Paypal IPN ? Paypal IPN take all the new params?

Thank you,
Leandro

1. yes

2. we send all the name/value pairs in the paypalParams array to paypalIPN. Note that we do not do store any name/value pairs that you might introduce in the civicrm database

Is that something new in 1.8+ ?

I've 1.7.9379 installed and didn't found that.
I know I should upgrade, but I need to do this quick fix and then after some donation campaigns finish I'll upgrade CiviCRM, but for now, is that possible in my version?

Thanks,
Leandro

Excellent, thank you.
