Currently I am getting some email reports from Marketo to my gmail Account, Is it possible to fetch these Reports directly from the API using PHP ?
No, there's no API to fetch rendered reports.
No, there is no API for reports but what you can do is to fetch the activity data in database and use that to create reports.
Since Marketo have 90 days and 25 month data retention policy, it makes sense to have a backup database to have historical activity data.
