I have successfully got our orders coming into xero from shopify but it does not bring the shipping costs. I found an old article suggesting to use “Add item to existing sales invoice in xero” however I get an error. The email notification from Zap is “A validation exception occurred, Invoice Type must be specified, A Contact must be specified for this type of transaction” however Contact and Invoice Type are not an option in this new Zap section ‘Add tiem to existing sales invoice in xero”. All old forum topics are no longer available.
Can anyone help with what Im doing wrong or even point me in the direction if I should be trying another method.
Thanks heaps.
