We have a FormAssembly form that uses Paypal IPN notifications (webhooks) to update a record when payment is confirmed.

In the FormAssembly configuration, we have specified a publicly-available page on a Salesforce Site as the Paypal IPN URL.  This is all working fine - the record is updated successfully.

The issue is that in order to Enable IPNs on the Paypal side, we also need to specify an IPN URL in Paypal.  This is essentially a dummy URL as we only care about IPNs generated by FormAssembly.  We have specified the same Salesforce Site page.

The issue we are seeing is that if an IPN is generated outside of FormAssembly, via a legacy system for example, all calls to the IPN URL (the Salesforce Site page) result in a 503 error.  This causes Paypal to deactivate our IPNs - which also affects our FormAssembly integration!

If I look at the logs, the Paypal requests are not even reaching the IPNHandler page.  They are hitting /InMaintenance, as that is the page specified for 503 Server Unavailable responses.

If I access the Paypal IPN endpoint myself, the IPNHandler page is hit and a 200 OK status is returned.  The IPNHandler page is currently designed to swallow all exceptions.

Does anyone know why it might be different when Paypal is sending the IPN?  Has anyone seen this issue before?

Hi, I am trying to convert below javascript button into a lighting component.

{!REQUIRESCRIPT("/soap/ajax/29.0/connection.js")} 
// query the record 
var qr = sforce.connection.query("SELECT Id, SyncedQuoteId FROM Opportunity where Id='" + "{!Opportunity.Id}" + "'"); 
var records = qr.getArray("records"); 

var qr1 = sforce.connection.query("SELECT Id, OpportunityId FROM Quote where OpportunityId='" + "{!Opportunity.Id}" + "'"); 

// display the field from the query 
var recTypeId='{!Opportunity.RecordTypeId}'; 

var oppQuoteId=qr.records.SyncedQuoteId; 
var quoteRecord=qr1.getArray("records"); 

if((recTypeId=='{!$Setup.Opportunity_Record_Types__c.New_Record_Type_Id__c}' || 
recTypeId=='{!$Setup.Opportunity_Record_Types__c.Pilot_Record_Type_Id__c}' || 
recTypeId=='{!$Setup.Opportunity_Record_Types__c.Renew_Upsell_Record_Type_Id__c}') 
&& (oppQuoteId==null && quoteRecord!='')) { 
window.alert("There is a root quote already attached to this Opportunity. If you need assistance with this opportunity, please reach out to xxxxx "); 
} 
else {
window.open ("http://{!$Setup.Integration_Settings__c.Quoting_Tool_URL__c}/reps/xxxxx.aspx?SFAccountId={!CASESAFEID(Opportunity.AccountId)}&SFOppId={!CASESAFEID(Opportunity.Id)}"); 
}
