sendgrid events post not working

Question

I am trying to post SendGrid events back to my server. But I am not able to capture the data. When I try from the testing functionality, it is showing the response code as 200 and the posted data. But I am not able to capture it in my server side. I am using the following code

<?php
$postText = trim(file_get_contents('php://input'));
print_r($postText);
$fh = fopen('/tmp/dump.log','a+');
fwrite($fh,print_r($postText),'true');
fclose($fh);
?>

Nothing is written to the file. I tried to write something to same file for testing and it is working. So I think the file has all the permissions.

Answer 1

This is because you print the data by not passing second argument to the print_r function!

This line: fwrite($fh,print_r($postText),'true'); should look like this instead: fwrite($fh,print_r($postText, true));

Answer 2

I know this is already working, but wanted to share some sample code I use myself. (disclosure: I'm a SendGrid employee)

Very similar to your own code, but the RAW_POST_DATA global makes it pretty easy to fetch all POST data in one shot.

<?php

$fh = fopen("/tmp/sg_event.log", 'a+');
if ($fh) {
    fwrite($fh, print_r($HTTP_RAW_POST_DATA, true));
    fclose($fh);
}
?> ok
