Lead Merge Ways
Marketo support lead merge but it is either manually or contact Marketo Technical Support. Also, third party tool support to merge data.
Marketo already dedupe the leads for, list import, API, fills out form but CRM it do not support.
I was wondering if there are other possible ways while creating smart campaign to resolve this too. Please comment if any other method is open to achieve merge process
Also, in API data insertion process duplicate lead are being generated how can this be resolved in Marketo.
