An error occurs in the forms: “Webhook URL not available.” Why?

This error means that your server was unavailable and could not return the message “ok” to Tilda within 7000 milliseconds (7 seconds). You have to check if the script is correct and valid.

Here is an example of the correct code behavior while sending the information to the specified email.

<?php

$headers = "From: from@webhookservesite.com";
$message = print_r($_POST,true);
@mail('to@gmail.com', 'Tilda TEST', $message, $headers);

echo "ok";

?>
