Hi,

I've seen similar questions about this before but can't see that the solutions apply in my case. I've created a webhook which is correctly being trigged as can be seen in the Hubspot log at https://app.hubspot.com/workflows/5163272/platform/flow/87833251/history/log-events

 

Looking at the apache access log on my server no request is ever received via my target url https://test.yourdolphin.com/unsubscribe/fromhs.php yet if you go directly to that url in a browser it's just fine. The SSL vertificate on the server is valid and in date.

Hi @NFortin , I tried sending a POST request to your URL (https://test.yourdolphin.com/unsubscribe/fromhs.php) through Postman and I think I have found the issue.

When I disable the SSL verification, I do get a response. So I guess the HubSpot webhook is not passing because of the SSL issue.

Hi @NFortin ,

A webhook shows that result in the history page of the workflow when it has not received a valid response. In my case I had to set a valid HTTP response in order to debug the issue a bit further.
In your case, it seems as if the URL is never reached, but just to be sure, could you check if you send a response when a 'POST' is made to the file?

My endpoint script does not send a response, what response is required? However the endpoint is never reached, no incoming requests from Hubspot are present in the apache2 log file.

Hi @NFortin , Any HTTP response should work. Best to send just a default HTTP response with a success or error message. Remember, when you open the URL through your browser, it is a GET request. A HubSpot webhook sends a POST request with an object attached.
My best guess is to set a HTTP response and check if your file handles the POST requests correctly.

@NFortin You could also use Postman to test what happens when you send a POST request. You could temporarily set the webhook to point to https://webhook.site/ where you can get a unique URL to send the POST request to. In Postman, you could than simulate the POST request to your endpoint to analyze the response.

OK, so I create this test script on a different server:-

<?php
//The url you wish to send the POST request to
$url = 'https://test.yourdolphin.com/unsubscribe/fromhs.php';

$data = array('key1' => 'value1', 'key2' => 'value2');

// use key 'http' even if you send the request to https://...
$options = array(
'http' => array(
'header' => "Content-type: application/x-www-form-urlencoded\r\n",
'method' => 'POST',
'content' => http_build_query($data)
),
"ssl"=>array(
"verify_peer"=>false,
"verify_peer_name"=>false
)
);
$context = stream_context_create($options);
$result = file_get_contents($url, false, $context);


var_dump($result);
?>

I modified my endpoint script for the webhook to echo "OK!", it also writes the result of print_r($_POST) into a log file.

Running the test script above the var_dump($result) prints ' string(3) "OK!"' so its getting that response. The print_r($_POST) in my enpoint script is correctly showing:-

Array
(
[key1] => value1
[key2] => value2
)

so the POST request is working just fine.
