# Shopify A CRM connection is crucial for maintaining the quality and delivery of signals. It serves two main purposes:\ \ 1\. **Customer Activity Tracking**: We analyze past orders to determine whether a customer is a first-time buyer or a repeat customer.\ \ 2\. **Backup Mechanism**: In case of a failure in the browser, we can directly retrieve purchase data from Shopify, allowing us to link attribution to EdgeTag data effectively. {% hint style="warning" %} For the NC/RC feature to work, this step is necessary. {% endhint %} ### How does it work? We check for orders every 15 minutes. When you first add a channel, we will review the last 15 minutes for any orders. After the first successful synchronization, we will store the timestamp of the last synced order in the database. \ \ During subsequent checks, we will look for orders between the timestamp of the last synced order and the current time. If there are any new orders, we will update the database with the timestamp of the latest synced order. \ \ This process will be repeated every 15 minutes to ensure that no orders are missed. --- # 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.
