Trouble with POST data using gform_after_submission

Greetings,

I am attempting to use the gform_after_submission to post the results of a form to a 3rd party site. I have followed the examples from http://www.gravityhelp.com/documentation/page/Gform_after_submission and combined it with some outside support on the topic that I found here http://www.0to5blog.com/creative/gravity-forms-submitting-forms-to-3rd-party-applications/. And of course I am having trouble.

I have been able to verify that I can post to the 3rd party site and submit the data to their forms using a command-line "http-ping" tool passing the same parameters as the gform_after_submission should be passing. So the 3rd party site appears to be ready.

I used this same function to have the system email me the form IDs so that I would have them accurately. Here were my results of the Form IDs

Array
(
[1] => dan
    [2] => feeley
    [3] => dan(at)extremefitnessmartialarts.com
    [4] => (203)555-1212
    [5] => Mon
    [6] => 10AM
    [8] => 1403
    [9] => redirectpagehere
    [10] => 0
    [7] =>
)

I then created these functions and added them to my functions.php file as suggested in the working examples of http://www.gravityhelp.com/documentation/page/Gform_after_submission

Here are my functions:

add_action('gform_after_submission_23', 'post_to_third_party', 10, 2);
function post_to_third_party($entry, $form) {

    $post_url = 'https://addmembers.com/RainMaker/process/';
    $body = array(
 "SID" =>       $entry["8"],
 "EMail" =>     $entry["3"],
 "ReturnURL" =>  $entry["9"],
 "formID" =>    $entry["10"],
 "FName" =>     $entry["1"],
 "LName" =>     $entry["2"],
 "Phone" =>     $entry["4"]
        );

    $request = new WP_Http();
    $response = $request->post($post_url, array('body' => $body));

}

I limited it to happen on Gform 23, and also without the specific form ID number. Either way I do not get a post to the 3rd party system. So I am stumped. I am not a developer by any means, but I can certainly follow good instructions which these examples have. Can you spot anything obvious with this?

Is there a way to have Gforms go into a debug mode, or log what its doing to better troubleshoot?

Any assistance here is greatly appreciated!
