# full dokumentation on https://pushover.net/api
#
# POST an HTTPS request to https://api.pushover.net/1/messages.json with the following parameters:
# token (required) - your application's API token
# user (required) - the user/group key (not e-mail address) of your user (or you),
# viewable when logged into our dashboard (often referred to as USER_KEY in our documentation and code examples)
# message (required) - your message
#
# Some optional parameters may be included:
# device - your user's device name to send the message directly to that device,
# rather than all of the user's devices (multiple devices may be separated by a comma)
# title - your message's title, otherwise your app's name is used
# url - a supplementary URL to show with your message
# url_title - a title for your supplementary URL, otherwise just the URL is shown
# priority - send as
# -2 to generate no notification/alert,
# -1 to always send as a quiet notification,
# 0 (default) to send notification with sound, vibration and display(not in quiet hours)
# 1 to display as high-priority and bypass the user's quiet hours, or
# 2 to also require confirmation from the user
# retry
# expire
# timestamp - a Unix timestamp of your message's date and time to display to the user, rather than the time your message is received by our API
# sound - the name of one of the sounds supported by device clients to override the user's default sound choice
#
# That's it. Make sure your application is friendly to our API servers and you're all set.
# For more information on each parameter, keep reading or jump to a section at the left.
#
# Need help using our API or found an error in the documentation? Drop us a line.
