Webhooks in PHP

[Paul E.]

I have been playing round with the PHP SDK, but have not figured out exactly what I should be sending back for the verification request. the documentation rather ambigously says "Your app needs to respond by echoing back that challenge parameter." However the error returned states

Error: error:14077458:SSL routines:SSL23_GET_SERVER_HELLO:reason(1112)

Response:
(No headers)

Response Body (First 256 bytes):
(No response body)

Is there some sample code for PHP? The documentation only has Python.

Thanks,
Paul.

You need to return the value of the query string parameter called "challenge".

This PHP code should do the trick:

<?php
    echo $_GET['challenge'];
?>

Actually, I missed the SSL error in your post. If there's an SSL error, it means we can't even connect to your server to get a response. You'll need to resolve that issue first... if you need help, please open an API support ticket: https://www.dropbox.com/developers/contact.

Thanks for the quick response!
I tried a simple echo statement first, but it would seem the SSL error is causing the issue.
Oddly enough the SSLTester returns OK:
