shoppy.customer.init()
Initializes the customer session by checking for a stored access token. If a valid token exists, fetches and returns the customer data. Call this on page load to restore logged-in state.

​
Returns

Promise<ShopifyCustomer | null> - Customer object if logged in, null otherwise.

​
Examples

​
Basic initialization

// On page load
const customer = await shoppy.customer.init()

if (customer) {
    console.log(`Logged in as ${customer.email}`)
    showAccountMenu()
} else {
    showLoginForm()
}

​
With error handling

try {
    const customer = await shoppy.customer.init()

    if (customer) {
        updateUI(customer)
    }
} catch (error) {
    // Token was invalid or expired
    console.log('Session expired, please log in again')
}

​
Combined with subscribe

// Set up subscription first
shoppy.customer.subscribe((customer) => {
    updateNavbar(customer)
})

// Then initialize - will trigger subscriber with restored state
await shoppy.customer.init()
Always call .init() early in your page lifecycle. This restores the customer session and triggers any subscribers with the current state.
