# Running headless

Running headless BigCommerce with Engage comes with a few considerations:

1. **Abandoned cart** will not work, since it is tied to the BigCommerce front-end. To use abandoned cart, the tracking script must be manually implemented by whoever builds your custom front-end.

2. The **Engage widgets within the app** can't be used for merchants running the headless version since this is tied to the front-end. The information displayed -- vouchers, promotions, points and member levels -- can all be accessed through the Engage `/contacts` API.

3. The **syncing and creation of vouchers and assignment of promotions** in BigCommerce when customer log in is NOT available for merchants running the headless version.

4. **Soft identification** is tied to the front-end and is not available if running as headless.
