I got unknown Webhook error email about Order/Paid but I haven't create any Webhook on my Shopify account.
I wonder how come it is and how to fix that errror?
Thank you in advance for any help.
Solved! Go to the solution
@STsuthep, Go to your Shopify admin -> settings -> Notifications and scroll down to the bottom of the page. There you will see webhooks created by you or by your staff members. If you don't find any there is a chance that you installed an app that created a webhook via API and failing to return the 200 status.
This is an accepted solution.
@STsuthep From the screenshot that you attached the webhook that is failing to send the 200 response is https://shopify-service.xwfms.co.uk/. Are you using anything related to https://www.xwfms.co.uk/ please check it.
It seems like it is a fulfillment service which is failing to handle the webhooks correctly.
