How can I get a Custom Object's linked Lead's ID?
Hi,
I am making updates to Marketo Custom Objects via the rest API, and would also like make an update to the Lead that is linked to the custom object.
I know I can get the lead by filtering on the email address, but in the case that there are duplicate leads (same email address) I would need a way to differentiate which lead is linked to the custom object.
I was hoping there would be a simple way to get the Lead ID of the linked Custom Object, but I have not been able to find any based on the documentation and tests using the samples provided.
Is there a simple way of getting the Lead ID of lead linked on to the custom object?
