I am testing my code in small batches on Marketo Sandbox but have a problem. I see that new records are created from my CSV data. I only want to update.

Quote from The Marketo docs .

"You can specify id as lookupField to indicate an “update only” operation. "


Marketo bulk import should not create new records if you specify id as a lookupField. I am using `/bulk/v1/leads.json?format=csv&lookupField=id"`


If I look at the data new leads/persons with with a fake Id and fake email was created in the Sandbox env.
