I've got a FormAssembly form that creates a record in the EFI_Certificate__c object in Salesforce upon submit. The form accepts PayPal payments. Because the payment happens on PayPal's site, outside of FormAssembly, it creates the SF record before the person proceeds to the PayPal site for payment. Our staff needs to know when/if payment is posted so I need to be able to pass PayPal's IPN (Instant Payment Notification) that is normally posted on the FormAssembly record (once PayPal payment is complete) through to Salesforce. They have a nice article on how to do this using a VisualForce page and some apex coding. I have followed the instructions in the article, but the parmCustom variable in the apex is returning a null value instead of the value in the FormAssemblyID field. I have a included a link to the original article posted by FormAssembly, along with my apex class, VF page, and error log. Any help would be much appreciated.

I've got a FormAssembly form that creates a record in the EFI_Certificate__c object in Salesforce upon submit. The form accepts PayPal payments. Because the payment happens on PayPal's site, outside of FormAssembly, it creates the SF record before the person proceeds to the PayPal site for payment. Our staff needs to know when/if payment is posted so I need to be able to pass PayPal's IPN (Instant Payment Notification) that is normally posted on the FormAssembly record (once PayPal payment is complete) through to Salesforce. They have a nice article on how to do this using a VisualForce page and some apex coding. I have followed the instructions in the article, but the parmCustom variable in the apex is returning a null value instead of the value in the FormAssemblyID field. I have a included a link to the original article posted by FormAssembly, along with my apex class, VF page, and error log. Any help would be much appreciated.

Apex Class (IPNHandlerController)

 certificate = [select Id,paid__c from EFI_Certificate__c where FormAssemblyID__c = :paramCustom];

 String content = '';
 for(String key : pageRef.getParameters().keySet())
 //Note that there is no guarantee of order in the parameter key map.
 content += key + ' : ' + pageRef.getParameters().get(key) + 'n';
 
 certificate.PayPalInfo__c = content;
 certificate.paid__c = True;
 update certificate;

The error in the log says: System.QueryException: List has more than 1 row for assignment to SObject

If you have more than one certificate with that FormAssemblyID then that is why you are receiving the error.

On the line: certificate = [select Id,paid__c from EFI_Certificate__c where FormAssemblyID__c = :paramCustom];, if this query returns more than one record then an error will occur.
