This section defines what information is to be sent to the notify URL when callback is used.
The notify URL (specified in the [Settings] section) will receive this information and can respond by returning any extra parameters as name value pairs. For example:
These extra parameters will be used in addition to those passed on the command line or contained in the [Input] section.
A checksum may also be used in the [Callback] section and the [Output] section to validate the data being passed from PIP to the notify URL (specified in the [Settings] section) by setting an entry to have the value %CHECKSUM%.
The checksum is calculated using the values of all entries and is always added to the end of the data, for example:
This will send the output:
If the security KEY is set, this will be added to the end of the data values and included in the checksum.
