In Shopify, sessions refer to the temporary storage and management of customer-specific data during their visit to your online store. A session is created when a customer interacts with your store and ends when the customer leaves or their session expires. Here’s a detailed explanation of sessions in Shopify:

1. Purpose and Use:
– Sessions allow Shopify to track and maintain information about a customer’s visit to your store.
– They enable the store to remember customer-specific data and provide a personalised experience.
– Sessions are essential for various functionalities like cart management, user authentication, order processing, and tracking customer behavior.

2. Session Data:
– During a session, Shopify stores and manages various types of data, including:
– Cart Contents: The products and quantities added to the customer’s shopping cart.
– Customer Information: Details like name, email address, shipping and billing addresses, and any custom data associated with the customer.
– Session ID: A unique identifier assigned to each session to track and link customer actions.
– Authentication Status: Whether the customer is logged in or accessing the store as a guest.
– Order History: Information about the customer’s previous orders, if applicable.
– Referral Source: The URL or source that brought the customer to your store.

3. Managing Sessions:
– Shopify automatically handles session management, including the creation, storage, and deletion of session data.
– Session data is stored server-side and associated with a unique session ID, which is typically stored in a cookie on the customer’s device.
– The session ID allows Shopify to identify and retrieve the relevant session data for each customer.

4. Session Expiration:
– Sessions have a defined lifespan and expire after a certain period of inactivity or based on configurable settings.
– The default session expiration time in Shopify is 30 minutes of inactivity, but this can be customised through your store’s settings or with the help of apps or custom code.
– When a session expires, the stored session data is cleared, and the customer’s next visit starts a new session.

5. Security and Privacy:
– Shopify takes measures to ensure the security and privacy of session data.
– Session data is stored securely and is inaccessible to other customers or external parties.
– Personally identifiable information (PII) and sensitive data are handled following industry-standard security practices and compliance requirements.

6. Impact on Store Functionality:
– Sessions play a crucial role in various store functionalities, such as adding items to the cart, applying discounts, tracking order history, and maintaining personalised experiences.
– Sessions enable customers to browse and interact with your store seamlessly, preserving their data and settings throughout their visit.

Understanding sessions in Shopify helps you grasp how customer-specific data is managed during their interaction with your store. By leveraging sessions effectively, you can provide a personalised, smooth, and engaging experience for your customers, leading to increased conversions and customer satisfaction.
