  if (result.applePay) {
    collect.mount("collect-container", document, {
      paymentMethods: ["apple_pay"], // and or google_pay
      buttonOptions: {
        onClick: (event) => {
          ...
          const update = {
            total: ...,
            lineItems: [...],
            shippingMethods: [...],
            couponCode: ...,
          };
           
          if (event.source === "apple_pay") { // or google_pay
            collect.startApplePaySession(update); // or collect.startGooglePaySession(update)
          }
        },
      },
    });
  }
});
collect.supportWalletPayments().then((result) => {
  if (result.applePay) {
    collect.mount("collect-container", document, {
      paymentMethods: ["apple_pay"],
      applePayButtonOptions: {
        onClick: (event) => {
          ...
          const update = {
            total: ...,
            lineItems: [...],
            shippingMethods: [...],
            couponCode: ...,
          };
           
          collect.startApplePaySession(update);
        },
      },
    });
  }
});

# AbortApplePaySession() optional

This method is used to force close an Apple Pay payment sheet. Will have no effect if the Apple Pay payment sheet is not active at the time this method is called.

# Wallet Event Methods

# Complete(walletRequestUpdate) required

Method parameter: WalletRequestUpdate

This method is used to perform billing/shipping address validation before completing payment authorization and closing wallet payment sheet session. You can only pass WalletError object as part of the arguments/options.

collect.on("payment_authorized", (e) => {
    let update = {
        "error": {
            "code": "invalid_payment_data",
            "message": "Payment data is not valid"
        }
    };
    e.complete(update); // e.complete() for no error
}

# UpdateWith(walletRequestUpdate) optional

Method parameter: WalletRequestUpdate

Updates wallet request total, displayed items, shipping methods, coupon code and possibly error when wallet payment sheet is modified. This method should be used inside the following event handlers:

• Shipping Address Change
• Shipping Method Change
• Coupon Code Change

IMPORTANT WalletRequest.total is NOT calculated on-the-fly and it will be overwritten. You will need to handle the cost adjustment due to event triggers.

collect.on("shipping_address_change", (e) => {
  const options = {
    lineItems: [
      {
        label: "Express Shipping",
        amount: "7.00",          // wallet does NOT calculate total cost on-the-fly
      },
    ],
    total: {
      label: "Total",
      amount: OlsServer.calcShipping(e.shippingAddress, walletRequest.total.amount),
    },
  };
 
  e.updateWith(options);
});

In case you just wanted to display error without modifying existing line items, shipping methods, or total, simply just pass in WalletError as an option to updateWith method. Refer to Payment Sheet Errors and Input Validation for more detailed usage.

collect.on("shipping_address_change", (e) => {
  ...
  const options = {
    error: {
      code: "invalid_shipping_address",
      contactField: "locality",
      message: "We don't support shipping to SINALOA, choose different address",
    }
  };
 
  e.updateWith(options);
});
