# Upcart x Globo Product Options, Variant

> This article explains how to integrate Globo Product Options and Variant with Upcart to ensure both apps work together smoothly.

## Overview

On most themes, third-party apps like Globo modify the default **Add to Cart** button with a custom function. This can prevent Upcart from triggering properly, leading to cart redirects or skipped drawer openings.

***

## How to Fix

Follow these steps to adjust settings in both Upcart and Globo:

1. In the **Upcart** app, go to **Cart Editor > Settings > Advanced Settings**.
2. Enable the option **Enhanced Ajax API Compatibility**.

This setting improves compatibility with apps that use custom add-to-cart actions. Without it enabled, customers may be redirected to the store’s default cart page instead of seeing the Upcart drawer.

Next, update your Globo settings:

1. Open the **Globo Product Options** app.
2. Locate and disable the option:

   **“Redirect to the shopping cart page after adding a product.”**

Disabling this ensures that the Upcart drawer opens correctly after a product is added to the cart.

## Why This Happens

Globo Product Options replaces Shopify’s default **Add to Cart** process with a custom script. When this happens, Upcart cannot detect the cart update unless **Enhanced Ajax API Compatibility** is enabled.

Turning on this setting allows Upcart to recognize custom add-to-cart actions and prevents unwanted redirects to the default cart page.
