Web hooks in practice

//something ...hook_trigger(‘viewpage’);//more stuff..

async

asyncwhile(1) {

while($queued = $q->get(‘async-queue’)) { post_to_url($queued[‘url’],$queued[‘postargs’]);}

}

I want this to exist:

Trigger Filter Branch/Merge Transform Route

incoming web hook

$page =~/deploy/i

$to = [‘devel@’,ops@’]

$msg = fmt_to_aim($attrs) out_aim($to,$msg)

$uid == da39a3ee5e6b4b

$to = @all_sms;unset($to[$uid]);

$msg = fmt_to_sms($attrs)

out_sms($to,$msg)

$viewcount == 100 $to = $emails[$uid] $msg = “Wow you’re a power user”

out_email($to,$msg)

$op == ‘edit’ $to = [‘http://my.com/’,‘http://twittr.com/me’] $msg = $attrs out_hook($to,$msg);

= awesome but only polling (RSS)
