How to Override the Default Checkout Behavior in Corner Cart

By default, Corner Cart redirects to Shopify's default checkout page when a visitor clicks on the Checkout button in the cart. However, in some cases, you may want the user to be redirected to a custom checkout page or you may want to implement some other custom behavior. Fortunately, you can do this easily with the help of the following function available in our Cart SDK.

Step 1: Use the Override Checkout Function

To override the default checkout behavior, use the corner.overrideCheckout() function. This function takes a callback function as its parameter, and that callback function will be executed whenever the user clicks the checkout button. Here's an example code snippet:

corner.overrideCheckout((cartObject, discountCodeApplied) => {
  console.log("Checkout Triggered");

Step 2: Paste the Code into the Script Editor

Now that you have the code snippet, you can paste it into your script editor in Corner Cart. To access the script editor, go to Cart Drawer > Advanced Settings > Script Editor.

Step 3: Customize the Callback Function (Optional)

The corner.overrideCheckout() function also provides two parameters that you can use inside the callback function for more advanced functionalities:

cartObject: The Cart Object
discountCodeApplied: Any discount codes applied using the cart.
Feel free to customize the callback function to suit your needs.


In conclusion, overriding the default checkout behavior in Corner Cart is easy with the corner.overrideCheckout() function. Use it to redirect the user to a custom checkout page or to implement any other custom behavior you want.
