Sebastian Wachinger commented on OFBIZ-4075: -------------------------------------------- Actually this is one of the most enlightening threads on this issue to be found. Is there a more detailed timeline available for the three stages of the PayPal integration as outlined in the description by BJ? I was not aware that IPN is not supported anymore, or is it? Anyway, using it as is in the trunk now, it always renders the error _No valid orderId returned with PayPal Callback_, as the IPN parameter {code:xml}invoice{code} is used for {{orderID}} but for whatever reason is not transmitted and even does not show up in the otherwise complete parameter listing in {{console.log}}. I suspect this to be the reason for no order confirmation being sent out to the shop's admin eventually, which we always receive when payment methods other than PayPal Express Checkout are used. Any input on this issue is highly appreciated! > multiple paypal interfaces > -------------------------- > > Key: OFBIZ-4075 > URL: https://issues.apache.org/jira/browse/OFBIZ-4075 > Project: OFBiz > Issue Type: Improvement > Components: accounting > Affects Versions: Trunk > Reporter: BJ Freeman > Attachments: OFBIZ-4075paypalIPNEvents.pact > > > Pay pal had many interfaces. > Ofbiz started with IPN https://www.paypal.com/ipn > Then went to Express check out but changed the IPN code. > https://www.paypal.com/us/cgi-bin/webscr?cmd=_additional-payment-overview > finally we have NVP API. > https://cms.paypal.com/us/cgi-bin/?cmd=_render-content&content_ID=developer/e_howto_api_nvp_NVPAPIOverview > so I am creating an IPN interface that goes back to 777794 > I am not familiar enough with express and NVP it they are separate or not. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
