Registering Webhook generates an error: 422 Unprocessable Entity

[danhanly]

This, I'm sure is something to do with the encoding of the webhook data; not being created correctly for JSON.

Following the POST details on this page, I'm getting the 422 Unprocessable Entity error.

I posted to a request bin to see what exactly was getting passed, and the following is the output:

{"webhook":{"topic":"orders\/create","address":"http:\/\/localhost\/action\/order\/1","format":"json"}}

Weird thing is, this looks correct, but Shopify keeps rejecting it.

Code to reproduce:

$webhookData = [
    'webhook' => [
        'topic' => 'orders/create',
        'address' => url('/action/order', $this->store->id),
        'format' => 'json'
    ]
];

$response = $api->call(
    [
        'METHOD' => 'POST',
        'URL' => '/admin/webhooks.json',
        'DATA' => $webhookData
    ]
);

Hm, I've never had an issue with that, using almost identical code. Can you get the error message body? Sometimes Shopify will return errors.

From https://docs.shopify.com/api/webhook

Trying to create a webhook without an address or topic will return an error

POST /admin/webhooks.json

{
  "webhook": {
    "body": "foobar"
  }
}

Managed to Dump the full error response and it was because the webhook already existed for that topic/address.

@danhanly How did you manage to dump the full output. I need it on urgent basis.

orders\/create

Localhost won't work as a URL. In my case I was getting an error because I had typo in topic name I was using product/create instead of products/create
