I've been testing webhooks on our development store, and I registered for the carts/create and checkouts/create topics. When I went to our development store, I clicked to add a product to the cart, then clicked to checkout. I checked the logs for our webhook, and saw no logging (it hadn't been called). I thought it wasn't working since I saw no logging. however, the next day, I saw the log events had fired a day later. I believe it was roughly 12 hours or so later after actually clicked to add to the cart and checking out.
I've tried a couple more times, and that seems to be the case. Does anyone know how long it is supposed to take for an event to trigger a call to your registered endpoint? That is, if a person clicks to checkout, and you've registered a webhook to receive that event, is it supposed to be fired within seconds of someone clicking to checkout, or is it customary for it to take hours? Or is this just a development store quirk?
Just FYI: I know the webhook logs immediately when invoked, because when I call it in Postman, it logs right away.
Hello provenq ,
Web-hooks are immediately triggered when event is fired and as its not working in yours then you should check the below given points:-
1) The server on which the request is send should be SSL certified with A grade.
2) We have to verify the request. You can use this code to verify it:-
function verify_webhook($data, $hmac_header)
$calculated_hmac = base64_encode(hash_hmac('sha256', $data, SHOPIFY_APP_SECRET, true));
return hash_equals($hmac_header, $calculated_hmac);
Want to modify or custom changes on store hire us.
