Webhook fires twice occasionally

[Christopher Burns]

Hi all,

I am having a weird issue where on occasion I will get two calls to my webhook within 1s of each other (usually on the order of a few hundred milliseconds).

I have a log writing out the timestamp of a call, with code that looks like this:

$insightlyAPI = new Insightly(INSIGHTLY_SECRET);

$hmacHeader = $_SERVER['HTTP_X_SHOPIFY_HMAC_SHA256'];

$requestBody = file_get_contents("php://input");

$isValidWebhookRequest = verifyWebhook($requestBody, $hmacHeader);

if ($isValidWebhookRequest) {

    LOG_ERROR("***** Webhook request from Shopify *****", LogLevel::HIGH);

    $orderJSON = json_decode($requestBody);

    processOrderData($orderJSON);

}

else {

    //  ERROR!!! Bogus request?

    LOG_ERROR("ERROR: Invalid webhook request from {$_SERVER['REMOTE_ADDR']}");

}

I get a call from Shopify, begin processing the order, and immediately get another webhook call, which causes all sorts of problems.

Is anyone else experiencing this?

Cheers,

Chris
