6 years ago I don't completely understand, are you having issues with this specific call or all of them?
Can you send the raw post from paypal, as well as your reply.
I assume you are using the PHP sample?

6 years ago Hello, thanks for answering. I have the problem with paypal ipn where I use IPN-SIMULATOR. Ok in that. Now when I use it, it gives me that log, I use this PHP code:
<?php
//Permite crear un archivo LOG cada vez que se ejecuta este script, 0 para desactivarlo
define("DEBUG", 1);
// 1 para usarlo con el simulador de paypal (https://developer.paypal.com/developer/ipnSimulator/), 0 para usarlo con pagos reales
define("USE_SANDBOX", 1);
// este es el archivo LOG no importa si no existe este lo crea automaticamente
define("LOG_FILE", "resultadopaypal.txt");
// permite verificar si los datos son recibidos desde paypal y no otra pagina diferente
$raw_post_data = file_get_contents('php://input');
$raw_post_array = explode('&', $raw_post_data);
$myPost = array();
foreach ($raw_post_array as $keyval) {
$keyval = explode('=', $keyval);
if (count($keyval) == 2) {
// Since we do not want the plus in the datetime string to be encoded to a space, we manually encode it.
if ($keyval[0] === 'payment_date') {
if (substr_count($keyval[1], '+') === 1) {
$keyval[1] = str_replace('+', '%2B', $keyval[1]);
}
}
$myPost[$keyval[0]] = urldecode($keyval[1]);
}
}
$req = 'cmd=_notify-validate';
$get_magic_quotes_exists = false;
if (function_exists('get_magic_quotes_gpc')) {
$get_magic_quotes_exists = true;

foreach ($myPost as $key => $value) {

?>Now if I using ipn simulator I delete the option of the date everything works fine. What can I do in this case? What do you recommend?
PD: sorry for my bad English, I'm more of Spanish. Greetings and thanks

6 years ago The IPN Simulator always returns INVALID for verification requests. I was able to take my code that is getting INVALID in IPN simulator, and it works fine in production.

6 years ago I have the same issue. I used the latest code example from github, and it always returns INVALID. I am trying already since 3 days to find a solution, and cant figure out whats wrong. I did not change the github example, except adding my email address. I get also an email, with INVALID.
