Dynamically customize shipping options

Learn how to create different shipping rates for your customers.

Learn how to dynamically update shipping options based on the address that your customer enters when you use Checkout.

Use cases

Validate an address : Confirm whether you can ship a product to a customer’s address using your own custom validation rules. You can also create a custom UI for customers to confirm their preferred address.
Show relevant shipping options : Display only available shipping methods, based on the customer’s address. For example, show overnight shipping only for deliveries in your country.
Dynamically calculate shipping rates : Calculate and display shipping fees based on a customer’s delivery address.
Update shipping rates based on order total : Offer shipping rates based on the shipping address or order total, such as free shipping for orders over 100 USD. For checkouts allowing quantity changes or cross-sells, see Dynamically updating line items .

Limitations

Only supported in payment mode . Shipping rates aren’t available in subscription mode.
Not compatible with the Express Checkout Element . Wallets such as Apple Pay and Google Pay collect the shipping address directly, which bypasses the server-only update flow. When permissions. update _ shipping _ details is set to server _ only , these wallets are automatically disabled.

Payment Intents API

If you use the Payment Intents API, you must manually update shipping options and modify the payment amount based on a selected shipping option, or by creating a new PaymentIntent with adjusted amounts.

Configure update permissions for the Checkout Session Server-side

Set the shipping_address_collection.allowed_countries to the list of countries you want to offer shipping to.

When you create the Checkout Session, pass the permissions.update_shipping_details=server_only option to disable the client-side updateShippingAddress method and to enable updating the shipping address and shipping options from your server.

Update the client SDK Client-side

Initialize Stripe.js.

checkout.js

const stripe = Stripe('pk_test_TYooMQauvdEDq54NiTphI7jx');

Request server updates Client-side

Create an asynchronous function that makes a request to your server to update the shipping options and wrap it in runServerUpdate. A successful request updates the Session object with the new shipping options.

The following code example shows how to update the shipping options with the AddressElement.

index.html

<div id="shipping-form">
 <!-- Shipping Address Element will be mounted here -->
 <div id="shipping-address-element"></div>
 <button id="save-button">Save</button>
 <div id="error-message"></div>
 </div>

 <div id="shipping-display" style="display: none">
 <div id="address-display"></div>
 <button id="edit-button">Edit</button>
 </div>

checkout.js

// mount the Shipping Address Element
const shippingAddressElement = checkout.createShippingAddressElement();
shippingAddressElement.mount('#shipping-address-element');

const toggleViews = (isEditing) => {
 document.getElementById('shipping-form').style.display = isEditing ? 'block' : 'none';
 document.getElementById('shipping-display').style.display = isEditing ? 'none' : 'block';
}

const displayAddress = (address) => {
 const displayDiv = document.getElementById('address-display');
 displayDiv.innerHTML = `
 <div>${address.name}</div>
 <div>${address.address.line1}</div>
 <div>${address.address.city}, ${address.address.state} ${address.address.postal_code}</div>
 `;
}

const updateShippingOptions = async (shippingDetails) => {
 const response = await fetch("/calculate-shipping-options", {
 method: "POST",
 headers: { 'Content-type': 'application/json' },
 body: JSON.stringify({
 checkout_session_id: 'session_id',
 shipping_details: shippingDetails
 })
 });

 const result = await response.json();

Test the integration

Follow these steps to test your integration, and ensure your custom shipping options work correctly.

Set up a sandbox environment that mirrors your production setup. Use your Stripe sandbox API keys for this environment.
Simulate various shipping addresses to verify that your calculateShippingOptions function handles different scenarios correctly.
Verify server-side logic by using logging or debugging tools to confirm that your server:

Retrieves the Checkout Session .
Validates shipping details.
Calculates shipping options.
Updates the Checkout Session with new shipping details and options. Make sure the update response contains the new shipping details and options.

Verify client-side logic by completing the checkout process multiple times in your browser. Pay attention to how the UI updates after entering shipping details. Make sure that:

The runServerUpdate function is called when expected.
Shipping options update correctly based on the provided address.
Error messages display properly when shipping is unavailable.

Enter invalid shipping addresses or simulate server errors to test error handling, both server-side and client-side.
