System token for ID
Is Marketo provide system token for "Id" ? If not, then is there any alternate method to get the Marketo lead Id in POST API Webhook call.

{{Lead.Id}} is the built-in token.
(Don't know what you mean by "POST API Webhook call": webhooks are Marketo's outbound API, so are you trying to include the ID in the outbound payload?)
