Fetch Ticket message body using 'TestSimple' invoker of 'ArticleCreate' trigger

Question

I'm using invoker TestSimple.pm of trigger 'ArticleCreate'. (Ideally should've created a new invoker!) I'm able to receive the json data of the ticket correctly via REST web service. I want an additional ticket attribute with this-> 'ticket body'. How can i modify the invoker (perl file) so that it also sends ticket body in the json data? Or is their any other trigger that can give me this out-of-the-box? I went through OTRS manual and getting confused again-n-again :( So, if someone can give me proper link that will also do!

System details: 1. OTRS v4.0 2. Apache web server

[Edit] Added the TestSimple.pm file. This is the link I referred.

=cut

=item new()

usually, you want to create an instance of this
by using Kernel::GenericInterface::Invoker->new();

=cut

sub new {
my ( $Type, %Param ) = @_;

# allocate new hash for object
my $Self = {};
bless( $Self, $Type );

# check needed params
if ( !$Param{DebuggerObject} ) {
return {
Success => 0,
ErrorMessage => "Got no DebuggerObject!"
};
}

$Self->{DebuggerObject} = $Param{DebuggerObject};
$Self->{TicketObject} = Kernel::System::Ticket->new(%Param);

return $Self;
}

=item PrepareRequest()

prepare the invocation of the configured remote webservice.
This will just return the data that was passed to the function.

my $Result = $InvokerObject->PrepareRequest(
Data => { # data payload
...
},
);

my %Article = $TicketObject->ArticleGet(
ArticleID => $Param{Data}->{ArticleID},
UserID => $Param{Data}->{CustomerID},
);

$Result = {
Success => 1, # 0 or 1
ErrorMessage => '', # in case of error
Data => { # data payload after Invoker
...
},
};

=cut

sub PrepareRequest {
my ( $Self, %Param ) = @_;
my %TicketInfo = $Self->{TicketObject}->ArticleGet(
ArticleID => $Param{Data}->{ArticleID},
userID => $Param{Data}->{CustomerID},
);

return {
Success => 1,
Data => $TicketInfo{Body},
};
}

=item HandleResponse()

handle response data of the configured remote webservice.
This will just return the data that was passed to the function.

my $Result = $InvokerObject->HandleResponse(
#my $Result = $TicketBodyObject->HandleResponse(
ResponseSuccess => 1, # success status of the remote webservice
ResponseErrorMessage => '', # in case of webservice error
Data => { # data payload
...
},
);

$Result = {
Success => 1, # 0 or 1
ErrorMessage => '', # in case of error
Data => { # data payload after Invoker
%Article
},
};

=cut

sub HandleResponse {
my ( $Self, %Param ) = @_;

# if there was an error in the response, forward it
if ( !$Param{ResponseSuccess} ) {
return {
Success => 0,
ErrorMessage => $Param{ResponseErrorMessage},
};
}

return {
Success => 1,
Data => $Param{Data},
};
}

Answer 1

PrepareRequest only knows about the TicketID and ArticleID it is operating on. You'll need to look up the data you need to pass in the PrepareRequest() sub of your Invoker, and then return it in the Data parameter.

Check the code below for an example how to add the article body:

sub PrepareRequest {
    my ( $Self, %Param ) = @_;

    my %Article = $Kernel::OM->Get('Kernel::System::Ticket')->ArticleGet(
        ArticleID => $Param{Data}{ArticleID},
        UserID => 1,
    );

    return {
        Success => 1,
        Data => {
            TicketID  => $Param{Data}{TicketID},
            ArticleID => $Param{Data}{ArticleID},
            Body      => $Article{Body},
        },
    };
}
