What Aia suggested is fine if you're using a system where /bin/sh is not a pure Bourne shell (as it is on Solaris systems) or a 1988 Korn shell (as it is on many AIX systems). But, in addition to what Aia already commented on, there is nothing in your script that sets the shell variable _infos, so, unless that variable is being inherited from an exported variable in the environment of your script, the $_infos in your invocations of curl will be replaced by an empty string by the shell each time it invokes curl.
When posting questions to these forums, it always helps us provide answers that will work better in your environment if you tell us what operating system and shell you're using when you post questions. And, if you're using shell variables that aren't defined in your script, please tell us where those variables are being initialized.
If you are using a Solaris system or an AIX system or an HP/UX system, you're likely to get a bunch of syntax errors from Aia's suggestion, and we'll need to know which OS you're using, whether we can use a shell other than /bin/sh on your system (such as /usr/xpg4/bin/sh on a Solaris system or /bin/ksh93 on AIX) so we'll know if we can just use a different shell or if we need to convert the shell substring expansion into a single awk script (if you're stuck with a pure Bourne shell) or into POSIX conforming variable expansions in other shells.

hylafax-shutdown
HYLAFAX-SHUTDOWN(5) File Formats Manual HYLAFAX-SHUTDOWN(5)
NAME
etc/shutdown - server shutdown control file
DESCRIPTION
If the file etc/shutdown is present it describes when a HylaFAX server is to be shutdown and may contain a descriptive message to return to
clients explaining the reason for the shutdown. This file is used by the hfaxd(8) program.
The file has the following format:
<year> <month> <day> <hour> <minute> <deny> <disconnect>
<shutdown message text>
The first line defines the date and time the server should be shutdown and the time preceding at which unprivileged clients should be
denied service or disconnected; these fields are described in more detail below. Any lines that follow the first are taken as the text of
a message to return to clients when notifying them of a scheduled shutdown or when denying them service.
<year> The decimal year; e.g. 1996.
<month> The decimal month; e.g. 10 for October.
<day> The decimal day of the month in the range [1..31].
<hour> The decimal hour since midnight; in the range [0..23].
<minute> The decimal minute after the hour; in the range [0..59].
<deny> The time prior to the shutdown time at which to deny service to unprivileged clients. This value is specified as decimal number
in the form HHMM; e.g. 130 for 1 hour and 30 minutes.
<disconnect>
Time time prior to the shutdown time at which to disconnect unprivileged clients that are logged in to the server. This value is
specified as a decimal number in the form HHMM.
NOTES
This file is typically created using the ``SHUT'' command supported by hfaxd(8).
