Comment intercepter la requête HTTP POST envoyé par un Shopify Webhook

Désolé, je n'ai pas assez de réputation pour poster des commentaires, mais ici, c'est le contenu du lien mort d'Edward Ocampo-Gooding réponse:

En PHP, par Exemple w/SimpleXML (PHP 5+)

Le script ci-dessous vous montre comment récupérer les données XML à partir de Shopify dans votre script, archive le fichier et envoyer le bon en-têtes ...

Étant donné que le nouvel ordre de la configuration de l'abonnement dans l'admin pour le webhook est: http://example.com/some-script.php?key=123456789

Contenu de some-script.php sur http://example.com/:

<?     
//Protect URL from rogue attacks/exploits/spiders
//Grab from GET variable as given in Shopify admin URL
//for the webhook
//
//NOTE: This is not necessary, just a simple verification
//
//A digital signature is also passed along from Shopify,
//as is the shop's domain name, so you can use one or both of those
//to ensure a random person isn't jacking with your script (or some
//spider just randomly hitting it to see what's there).
//
//If $key doesn't matched what should be passed in from the
//webhook url, the script simply exits
$key = $_GET['key']; 
if ($key != '123456789') {
header('HTTP/1.0 403 Forbidden');
exit();
}
//Variables used for processing/saving
$xmlString = ;  //Used to get data from Shopify into script
$name = ;  //Saves the billing address name to be used for later ...
$email = ;  //Save the email address of the user to be used for later ...
$productTitles = array();  //Saves all titles of products purchased to be used for later ... 
//Get XML data and read it into a string for use with SimpleXML
//Thanks to David Oxley (http://www.numeriq.co.uk) for help with this
$xmlData = fopen('php://input' , 'rb'); 
while (!feof($xmlData)) { $xmlString .= fread($xmlData, 4096); }
fclose($xmlData);
//Save order XML in file in orders directory
//This creates a file, write the xml for archival purposes, and closes the file ...
//If the file already exists, it appends the data ... this should create a separate
//file for every order but if two orders are processed the same second, they'll both
//be in the same file
file_put_contents('orders/order' . date('m-d-y') . '-' . time() . '.xml', $xmlString, FILE_APPEND);
//Use SimpleXML to get name, email, and product titles
//SimpleXML allows you to use the $xml object to easily
//retrieve the data ...
//Please note, if hyphens are used in the xml node, you must
//surround the call to that member with {'member-name'} as is
//shown below when getting the billing-address name & the
//line items
$xml = new SimpleXMLElement($xmlString);
$name = trim($xml->{'billing-address'}->name);
$email = trim($xml->email);
//Create productTitles array with titles from products
foreach ($xml->{'line-items'}->{'line-item'} as $lineItem) {
array_push($productTitles, trim($lineItem->title));
}
//You would then go on using $name, $email, $productTitles in your script
//to do whatever the heck you please ...
//Once you are done doing what you need to do, let Shopify know you have 
//the data and all is well!
header('HTTP/1.0 200 OK');
exit();
//If you want to tell Shopify to try sending the data again, i.e. something
//failed with your processing and you want to try again later
header('HTTP/1.0 400 Bad request');
exit();
?>

Pour répondre à votre question à propos de l'URL, c'est le point de terminaison sur votre serveur qui va gérer la réception de la webhook. C'est assez simple à mettre en place avec la plupart des frameworks web, il faut juste gérer le demande et d'y répondre avec une réponse 200 OK.

Une fois que vous avez un point de terminaison installé sur votre serveur, vous pouvez créer le webhook sur shopify avec l'URL étant le point de terminaison sur le serveur web.
