Re: [rt-users] Slack integration?

[Maciej Dobrzanski]

I wrote a module for this a while back. You just need to save it as 
local/lib/RT/Extension/Slack.pm and in RT_SiteConfig.pm you need to 
define SlackIncomingWebhookURL and SlackIncomingWebhookToken. Then you 
can simply call RT::Extension::Slack::Notify(%paramhash) wherever you 
need.

For example:
    RT::Extension::Slack::Notify(username   => 'Mr. RT',
                                 icon_emoji => 
':heavy_exclamation_mark:',
                                 text       => $text);

--- Slack.pm ---
package RT::Extension::Slack;

use HTTP::Request::Common qw(POST);
use LWP::UserAgent;
use JSON;

sub Notify {
  my %args = @_;
  my $payload = {
    username   => 'Mr. RT',
    icon_emoji => ':ghost:',
    text       => 'I have forgotten to say something',
  };
  my $service_endpoint;
  my $service_token;

  foreach (keys %args) {
    $payload->{$_} = $args{$_};
  }
  if (!$payload->{text}) {
    return;
  }
  my $payload_json = encode_json($payload);

  $service_endpoint = RT->Config->Get('SlackIncomingWebhookURL');
  $service_token = RT->Config->Get('SlackIncomingWebhookToken');
  if (!$service_endpoint || !$service_token) {
    return;
  }

  my $ua = LWP::UserAgent->new;
  $ua->timeout(10);

  $RT::Logger->info('Pushing notification to Slack: '. $payload_json);
  my $r = POST($service_endpoint .'?token='. $service_token,
               [ 'payload' => $payload_json ]);

  my $response = $ua->request($r);
  if ($response->is_success) {
    $RT::Logger->info('Successfully pushed notification to Slack');
  }
  else {
    $RT::Logger->error('Failed to push notification to Slack ('.
                       $response->code .': '. $response->message .')');
  }
}

This is an example action module that uses the Slack extension:

--- NotifySlackOnCreate.pm ---
use strict;
use warnings;

use base qw(RT::Action);

=head2 Prepare

=cut

sub Prepare {
    my $self = shift;

    return 1;
}

=head2 Commit

=cut
sub Commit {
    my $self = shift;
    my $text;
    my $requestor;
    my $ticket = $self->TicketObj;
    my $queue = $ticket->QueueObj;
    my $url = join '',
                   RT->Config->Get('WebPort') == 443 ? 'https' : 'http', 
'://',
                   RT->Config->Get('WebDomain'),
                   RT->Config->Get('WebPath'),
                   '/Ticket/Display.html?id=',
                   $ticket->Id;

    $requestor = $ticket->RequestorAddresses || 'unknown';
    $text = sprintf('Ticket #%d by %s has been created in %s | '.
                    '<%s|click to open>', $ticket->Id, $requestor,
                    $queue->Name, $url);

    RT::Extension::Slack::Notify(icon_emoji => 
':heavy_exclamation_mark:',
                                 text       => $text);

    return 1;
}

Of course you can just turn the action module into a Scrip easily and 
use it for any event.
