Why is my webhook failing to return a successful response?

[vineetgupta]

Hello 

I have created a webhook using the curl function.

It is showing me errors like this.

Anyone, please let me know.

Your webhook for fulfillments/update at https://.../updatefulFillMentWehook is failing to return a successful response.

This webhook has been attempted 2 times. If your webhook continues to fail, it will be removed and your application will not receive any more notifications.

Here is my code.

$curl = curl_init();

curl_setopt_array($curl, array(

  CURLOPT_URL =>  $curl_url_webhooks,

  CURLOPT_RETURNTRANSFER => true,

  CURLOPT_ENCODING => "",

  CURLOPT_MAXREDIRS => 10,

  CURLOPT_TIMEOUT => 30,

  CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,

  CURLOPT_CUSTOMREQUEST => "POST",

  CURLOPT_POSTFIELDS => "{\r\n\t\"webhook\" : {\r\n\t\t\t\"topic\" : \"fulfillments\/update\",\r\n\t\t\t\"address\": \"https://...../updatefulFillMentWehook\",\r\n\t\t\t\"format\": \"json\"\r\n\t}\r\n}",

  CURLOPT_HTTPHEADER => array(

    "cache-control: no-cache",

    "content-type: application/json",

    "postman-token: 903957eb-e03a-95ae-da3d-92b8c061d936",

    "x-shopify-access-token: ".$curl_token

  ),

));

$response = curl_exec($curl);

$err = curl_error($curl);

curl_close($curl);

if ($err) {

 // echo "cURL Error #:" . $err;

} else {

 // echo $response;

}

Can you please help anyone with this?

Thanks

Hi @vineetgupta 

Is that all code?

Then you have not return anything to webhook.

if ($err) {
 // echo "cURL Error #:" . $err;
} else {
 // echo $response;
 return json_encode(array(['msg'=>'success']));
}
