TS
refreshClientSession(): Promise<Boolean>
Update the checkout with the latest client session.

​
Overview

When updating client sessions dynamically, merchants must call refreshClientSession to ensure the Universal Checkout has access to the most recent session changes. This method synchronizes the client-side representation with server-side updates.

​
Usage Guidelines

  • Call refreshClientSession immediately after updating the client session via PATCH /client-session
  • Ensures the checkout UI displays the correct updated information (currency, amount, etc.)
  • Returns a boolean indicating the refresh operation’s success

​
Important Limitations

  • This method only updates the client session data (currency, amount, etc.) in the checkout
  • It does not refresh the list of available payment methods or saved payment methods
  • It’s critical to call this method after updating the client session to avoid payment declines especially for certain payment methods that are frontend-driven (Apple Pay, Google Pay, PayPal, and Klarna)
  • Some payment methods have specific limitations:
    • PayPal does not support currency updates and may require a complete SDK reload

​
Example

TS
// After you've updated the client session via the API endpoint
// PATCH /client-session

// Initialize Universal Checkout
const checkout = await Primer.showUniversalCheckout(clientToken, options);

// Refresh client session to access the latest changes
const success = await checkout.refreshClientSession();
For complete information on how to update a client session, see our Manage client sessions documentation.

​
Platform Support

This method is currently available on the Web SDK. Mobile platforms (iOS, Android, React Native) require re-initializing the checkout to refresh the client session.
