startMinutesAgo property
The inclusive start minute for the query as a number of minutes before now.
For example, "startMinutesAgo": 29 specifies the report should include
event data from 29 minutes ago and after. Cannot be after endMinutesAgo.
If unspecified, startMinutesAgo is defaulted to 29. Standard Analytics
properties can request up to the last 30 minutes of event data
(startMinutesAgo <= 29), and 360 Analytics properties can request up to
the last 60 minutes of event data (startMinutesAgo <= 59).
Implementation
core.int? startMinutesAgo;
