Auth and State

Authentication token

The SDK injects Authorization automatically if a token exists.

client.setAuthToken('<jwt>');

const token = client.getAuthToken();
const loggedIn = client.isAuthenticated();

client.clearAuth();

Token storage uses localStorage with a cookie fallback strategy.

Guest checkout credentials

Guest flows are backed by local identifiers stored by module:

• cart credentials
• invoice credentials
• shipping credentials
• payment credentials
• discount code

Methods that depend on missing state return validation errors instead of throwing.

Cleanup APIs

client.clearCache();
client.clearCredentials();
client.clearAll();

client.cart.clearCart();
client.invoices.clearInvoice();
client.shipping.clearAddress();
client.payments.clearPayment();
