Pushed Notifications - minutes_out

How does one use the “minutes_out” feature for Pushed Notifications?

From the docs I don’t see how this could be done.

flightxml.flightaware.com/soap/F … p_SetAlert
Says: Supported event types are: e_filed e_departure e_arrival e_diverted e_cancelled

Thanks!

The minutes_out feature is not officially documented, however the “channel” argument may contain “{minutes_out xxx}” to request minutes out alerts with that xxx duration. That will cause an alert to be generated that many minutes prior to the estimated arrival time of the flight.
