# How it works The integration is installed into your Shopify store just like any other Shopify application. Once it's configured with your Givex API credentials, the integration serves as a two-way bridge between Shopify and Givex, handling data calls between the systems whenever a customer requests a balance lookup on their card, purchases a new card, or attempt to redeem an existing card. It's good to note that as this integration depends on access to checkout customisation and the Shopify Gift Card API, it's currently available only to merchants on the Shopify Plus platform. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
