There are many reasons lead-in cancel an order. If the customer buys the wrong items, the items which the customer wants to buy are sold out, fraudulent customers or the customer wants to cancel an order. In those cases, the admin can cancel an order if meeting one of two conditions:
-
- The order isn’t paid
-
- The order isn’t the fulfillment
Cancel an order is necessary for an admin. Because this activity happens frequently. If the admin doesn’t cancel the order, inventory, revenue, and customer indicators will be wrong. Besides, if you need data to report or evaluate your business, a complete list of canceled orders is certainly what you need.
So this is why Beehexa will show you how to cancel an order and retrieve a list of canceled orders using Postman.
Let’s explore one by one in this article.
Cancel An Order Using Postman
Step 1: Generate API credentials from the Shopify admin
-
- Log in to your Shopify admin
-
- Go to Apps – Manage private apps
-
- Click Create a new private app
-
- In the App details section, enter a name for your app and an emergency developer email.
-
- In the Admin API section, select the areas of your store that you want the app to access
-
- Click Save
The Admin API section displays the app’s API key and password when you save the app’s details.
Step 2: Cancel An Order Using Postman
-
- Log in to your Postman and create a new workspace
-
- Create a new POST with this URL:
https://{username}:{password}@{shop}.myshopify.com/admin/api/{api-version}/{resource}.json- {username} – The API key that you generated.
- {password} – The API password that you generated.
- {shop} – The name of your development store.
- {api-version} – The supported API version that you want to use.
- {resource} – A resource endpoint from the REST Admin API.
Or you can copy this example in the Shopify Admin, remember to change {resource} to {orders/order_id/cancel}:
https://33a72f01e02987636e1c1a9a4e95c840:[email protected]/admin/api/2022-01/orders/4253998743615/cancel.json
order_id=4253998743615
You can read Shopify API – Create An Order Using Postman blog to get the order_id, or you can follow this process to get the order_id:
- In the admin dashboard, choose orders, then click all orders.
- Choose the order you want to cancel.
- Copy the order_id in the URL
Paste the URL above.
Then click Send
Response:
The API will return all information about the canceled order.

}
Step 3: Verify The Result
In the admin, choose orders, and click all orders.
As you can see, the order is crossed out, indicating that the order was canceled successfully.
After this step, the admin must manually stop the fulfillment process (select product, package, delivery product for shipper,…) because canceling an order using Postman or Shopify is not linked with the fulfillment process.
Retrieve A List Of Canceled Orders
In Shopify dev docs, the document doesn’t show you how to retrieve a list of canceled orders. But in this article, Beehexa will guide you to get canceled order data when needed.
Step 1: Generate API credentials from the Shopify admin
-
- Log in to your Shopify admin
-
- Go to Apps – Manage private apps
-
- Click Create a new private app
-
- In the App details section, enter a name for your app and an emergency developer email.
-
- In the Admin API section, select the areas of your store that you want the app to access
-
- Click Save
The Admin API section displays the app’s API key and password when you save the app’s details.
Step 2: Retrieve A List Of Canceled Orders Using Postman
-
- Log in to your Postman and create a new workspace
-
- Create a new GET with this URL:
https://{username}:{password}@{shop}.myshopify.com/admin/api/{api-version}/{resource}.json- {username} – The API key that you generated.
- {password} – The API password that you generated.
- {shop} – The name of your development store.
- {api-version} – The supported API version that you want to use.
- {resource} – A resource endpoint from the REST Admin API.
Or you can copy this example in the Shopify Admin, remember to change {resource.json} to {orders.json?status=cancelled}:
https://33a72f01e02987636e1c1a9a4e95c840:[email protected]/admin/api/2022-01/orders.json?status=cancelled
Paste the URL above.
Then click Send
Response:
The API will return the list of canceled orders.
