Sync Customers even when deleted in Quickbooks with qbXML

Question

I synched a customer from my SaaS application into quickbooks using qbXML and web connector, I used the field ExternalGUID to be able to associate it to my internal customer in my application.

The customer synched fine in Quickbooks. But I am still testing my application, so I deleted the customer in quickbooks just to test my code again and be able to sync back the customer in Quickbooks.

But now when I try to add the customer I just deleted, I get this response from quickbooks:

Quickbooks doesn't seem to clear the item from the list of used ExternalGUID. How can I make sure the customer is re-added to quickbooks when I am using the same ExternalGUID again?

I am using the US desktop edition of quickbooks.

Answer 1

Don't use the ExternalGUID- there are issues with it, and it doesn't support older QuickBooks versions.

Your best bet is to store a link between the ListID and your internal application ID in your own application.
