Cancel Checkout after webhook was triggered
Hi @Alex_Beacon,
Nick here from Shopify.
Great question. While it's not possible to directly prevent a payment after the customer has gone through the checkout process, there are a couple of workarounds to help prevent this or modify it after a customer has checked out. Let's take a look at them below:
- If you are on the Shopify Plus plan you could look into using Shopify Flow. Shopify Flow is an automation platform that helps you easily automate tasks and processes within your store and across your apps. Some of the main tasks of flow focus on preventing high-risk orders.
- If you are not using Shopify Plus, something to remember is that once a customer has gone through the checkout process the best next step to do what you're looking to do would be to cancel the order and refund the customer. It's not possible to simply reverse the checkout process.
- Another workaround, if you are not on the Shopify Plus plan, would be using an app. There are a couple of different fraud protection apps, but the one which springs to my mind for your particular example is NoFraud Fraud Prevention. The feature which stuck out for me here that I think is actionable for you is "You can decide to manually cancel the orders we flagged as fraud (“Fail”) or you can set up the system to automatically cancel the fraudulent orders on your behalf."
Hopefully, this helps!
All the best, Nick
Hey @Alex_Beacon,
No problem at all. I understand what you're asking but I am not comfortable with direct API related questions personally. I did, however, discover you do need to have the location_ids of the items in the order to issue a refund from within an app.
From looking into this further, this is because of the multi-location inventory. If your app is to comply with multi-location inventory it must include the location_ids which you can read more about here.
Hopefully, this at least gives you more information as to why this might be.
