# Sends a POST equivalent to the following CURL command:

# curl -X POST https://sandbox.plaid.com/institutions/get \
#   -H 'content-type: application/json' \
#   -d '{
#     "client_id": String,
#     "secret":String,
#     "count": Number,
#     "offset": Number
#   }'

# Suppress some default headers that would automatically added..

$success = $task.Run()

    exit
}

# The application is now free to do anything else
# while the HTTP POST is in progress

# For this example, we'll simply sleep and periodically
# check to see if the HTTP POST is finished.

    # Sleep 100 ms.
    $task.SleepMs(100)
}

# When we get here, the task is either finished successfully or not, or was canceled/aborted.

# If the task was "canceled", it was canceled prior to actually starting.  This could
# happen if the task was canceled while waiting in a thread pool queue to be scheduled by Chilkat's
# background thread pool scheduler.  

# If the task was "aborted", it indicates that it was canceled while running in a background thread.  
# The ResultErrorText will likely indicate that the task was aborted.

# If the task "completed", then it ran to completion, but the actual success/failure of the method
# is determined by getting the result of the underlying method call.
# A task status of 7 indicates completion.

# When called synchronously, the PostJson2 method returns an HTTP response object,
# unless the method failed and there was no response to be had.
# Check to see if PostJson2 method failed (and thus there is no response object).

    $("The underlying task failed, and there is no HTTP response object.")
