REST API 400 Bad Request

[damcompany]

Hello, by today I receive payments from my game www.footballherogame.it, but users doesn't receive the money game they've bought.

I've tried to check my code

fputs($fp, $header . $req);
while(!feof($fp)){
$res = fgets($fp, 1024);

//if paypal said is VERIFIED
if(strtoupper(trim($res)) == "VERIFIED"){

//do things

}

I've looked that $res now it's not VERIFIED even if I receive the payment from the user, but I get

The requested URL "&#91;no&#32;URL&#93;", is invalid.<p> 

HTTP/1.0 400 Bad Request

<TITLE>Invalid URL</TITLE>

Could somebody help me?

This is a "me too" reply: getting exactly the same errors, starting some time about 4-6 days ago.

Will post of course when I find out the cause..

For completeness, I'm using this call and parameters:

$req = 'cmd=_notify-synch';

$tx_token = $_GET['tx'];

$auth_token = "(my auth token)";

$req .= "&tx=$tx_token&at=$auth_token";

// post back to PayPal system to validate
$header = "POST /cgi-bin/webscr HTTP/1.0\r\n";
$header .= "Content-Type: application/x-www-form-urlencoded\r\n";
$header .= "Content-Length: " . strlen($req) . "\r\n\r\n";

$fp = fsockopen ('ssl://www.paypal.com', 443, $errno, $errstr, 30);

It's either that, or there was some API change we missed.

I'm browsing the changelog now: https://developer.paypal.com/docs/release-notes/release-notes-2018/#

You have to update your scripts to HTTP 1.1

1.  modify the posted Header information from  

$header .= "POST /cgi-bin/webscr HTTP/1.0\r\n";

into 

$header .= "POST /cgi-bin/webscr HTTP/1.1\r\n";

2. add the Host variable to the header   that is typically missing in HTTP 1.0 requests!

 so add a line like

$header .= "Host: www.paypal.com\r\n";

if your script communicates with www.paypal.com  or  

change it to the proper used endpoint host  like   ipnpb.paypal.com 

good luck

Thank you 

That's so easily overlooked, thanks a lot.

The silly thing is, in a different part of the site there's also some "purchase code",

and it uses curl, which works fine.. (should've compared the two a bit better..)
