I would rather use the API endoint. The Munchkin account ID has no link to the pod, AFAIK.
In this case it is a REST API account not Munchkin. Still I want to be able to provide a link to a lead in Marketo like https://app-ab16.marketo.com/leadDatabase/loadLeadDetail?leadId=501 But I don't know the server affinity (app-ab16) for the lead. Is there anyway to programmatically learn this from the REST API account? Is there an endpoint or something I can hit to get this information?
