Checkout migration guide

Learn how to migrate from the legacy version of Checkout to the new version.

The legacy version of Checkout presented customers with a modal dialog that collected card information, and returned a token or a source to your website. In contrast, the new version of Checkout is a smart payment page hosted by Stripe that creates payments or subscriptions. It supports Apple Pay, Dynamic 3D Secure, and many other features.

The new version of Checkout provides maximum flexibility, with support for dynamic line items, Connect, re-using existing Customers, and advanced subscription features. You can also use the client-only integration which is quicker to get started with and is suitable for simpler product catalogs.

To migrate from the legacy version to the new version, follow the guide that most closely represents your business model. Each guide recommends an integration path along with example code.

Dynamic product catalog and pricing
For example, you have a large product catalog or require support for dynamically generated line items (such as donations or taxes).
Dynamic subscriptions
For example, you are a SaaS provider billing users and need support for advanced features.
Connect platforms and marketplaces
For example, you are operating a marketplace connecting service providers with customers.
Saving payment methods for future use
For example, you are operating a business which doesn’t charge the customer until after services rendered.
Simple product catalog with fixed pricing
For example, you are selling a few products with pre-determined prices.
Simple subscriptions
For example, you are a SaaS provider with a monthly subscription plan.

As you follow the relevant migration guide, you can also reference the conversion table for a mapping of specific parameters and configuration options between the two versions of Checkout.

Dynamic product catalog and pricing

If you are selling products where the amount or line items are determined dynamically (say, with a large product catalog or for donations), see accepting one-time payments.

You may have used the legacy version of Checkout to create a token or source on the client, and passed it to your server to create a charge. The new version of Checkout’s server integration, however, reverses this flow. You first create a Session on your server, pass its ID to your client, redirect your customer to Checkout, who then gets redirected back to your application upon success.

Before

With the legacy version of Checkout, you would display the dynamic amount and description and collect card information from your customer.

client.html

<form action="/purchase" method="POST">
  <script
    src="https://checkout.stripe.com/checkout.js"
    class="stripe-button"
    data-key="pk_test_TYooMQauvdEDq54NiTphI7jx"
    data-name="Custom t-shirt"
    data-description="Your custom designed t-shirt"
    data-amount="{{ORDER_AMOUNT}}"
    data-currency="usd">
  </script>
</form>

Next, you would send the resulting token or source to your server and charge it.

Terminal

curl https://api.stripe.com/v1/customers \
  -u sk_test_4eC39HqLyjWDarjtT1zdp7dc
: \
  -d "email"="customer@example.com" \
  -d "source"="{{STRIPE_TOKEN}}"
curl https://api.stripe.com/v1/charges \
  -u sk_test_4eC39HqLyjWDarjtT1zdp7dc
: \
  -d "customer"="{{CUSTOMER_ID}}" \
  -d "description"="Custom t-shirt" \
  -d "amount"="{{ORDER_AMOUNT}}" \
  -d "currency"="usd"

After

With the new version of Checkout, first create a Checkout Session on your server.

Terminal

curl https://api.stripe.com/v1/checkout/sessions \
  -u sk_test_4eC39HqLyjWDarjtT1zdp7dc
: \
  -d "payment_method_types[]"="card" \
  -d "line_items[][price_data][product]"="{{PRODUCT_ID}}" \
  -d "line_items[][price_data][unit_amount]"=1500 \
  -d "line_items[][price_data][currency]"="usd" \
  -d "line_items[][quantity]"=1 \
  -d "mode"="payment" \
  -d "success_url"="https://example.com/success" \
  -d "cancel_url"="https://example.com/cancel"

If you use one of our Client libraries, upgrade to the latest version of the library in order to use the Checkout Sessions API.

Next, pass the Session ID to your client and redirect your customer to Checkout to complete payment.

var stripe = Stripe('pk_test_TYooMQauvdEDq54NiTphI7jx');
var checkoutButton = document.getElementById('checkout-button');

checkoutButton.addEventListener('click', function() {
  stripe.redirectToCheckout({
    // Make the id field from the Checkout Session creation API response
    // available to this file, so you can provide it as argument here
    // instead of the {{CHECKOUT_SESSION_ID}} placeholder.
    sessionId: '{{CHECKOUT_SESSION_ID}}'
  }).then(function (result) {
    // If `redirectToCheckout` fails due to a browser or network
    // error, display the localized error message to your customer
    // using `result.error.message`.
  });
});

The customer will be redirected to the success_url once they complete payment.

If you need to fulfill purchased goods after the payment, refer to Checkout Purchase Fulfillment.

Dynamic subscriptions

If you are providing subscription services that are dynamically determined or require support for other advanced features, see setting up a subscription.

You may have used the legacy version of Checkout to create a token or source on the client, and passed it to your server to create a customer and subscription. The new version of Checkout’s server integration, however, reverses this flow. You first create a Session on your server, pass its ID to your client, redirect your customer to Checkout, who then gets redirected back to your application upon success.

Before

With the legacy version of Checkout, you would display the subscription information and collect card information from your customer.

client.html

<form action="/subscribe" method="POST">
  <script
    src="https://checkout.stripe.com/checkout.js"
    class="stripe-button"
    data-key="pk_test_TYooMQauvdEDq54NiTphI7jx"
    data-name="Gold Tier"
    data-description="Monthly subscription with 30 days trial"
    data-amount="2000"
    data-label="Subscribe">
  </script>
</form>

Next, you would send the resulting token or source to your server to create a customer and a subscription.

Terminal

curl https://api.stripe.com/v1/customers \
  -u sk_test_4eC39HqLyjWDarjtT1zdp7dc
: \
  -d "email"="customer@example.com" \
  -d "source"="{{STRIPE_TOKEN}}"
curl https://api.stripe.com/v1/subscriptions \
  -u sk_test_4eC39HqLyjWDarjtT1zdp7dc
: \
  -d "customer"="{{CUSTOMER_ID}}" \
  -d "items[0][price]"="{PRICE_ID}" \
  -d "trial_period_days"=30

After

With the new version of Checkout, first create a Checkout Session on your server.

Terminal

curl https://api.stripe.com/v1/checkout/sessions \
  -u sk_test_4eC39HqLyjWDarjtT1zdp7dc
: \
  -d "payment_method_types[]"="card" \
  -d "subscription_data[trial_period_days]"=30 \
  -d "line_items[][price]"="{PRICE_ID}" \
  -d "line_items[][quantity]"=1 \
  -d "mode"="subscription" \
  -d "success_url"="https://example.com/success" \
  -d "cancel_url"="https://example.com/cancel"

If you use one of our Client libraries, upgrade to the latest version of the library in order to use the Checkout Sessions API.

Next, pass the Session ID to your client and redirect your customer to Checkout to complete payment.

var stripe = Stripe('pk_test_TYooMQauvdEDq54NiTphI7jx');
var checkoutButton = document.getElementById('checkout-button');

checkoutButton.addEventListener('click', function() {
  stripe.redirectToCheckout({
    // Make the id field from the Checkout Session creation API response
    // available to this file, so you can provide it as argument here
    // instead of the {{CHECKOUT_SESSION_ID}} placeholder.
    sessionId: '{{CHECKOUT_SESSION_ID}}'
  }).then(function (result) {
    // If `redirectToCheckout` fails due to a browser or network
    // error, display the localized error message to your customer
    // using `result.error.message`.
  });
});

The customer will be redirected to the success_url once the customer and subscription have been created.

If you need to fulfill purchased services after the payment, refer to Checkout Purchase Fulfillment.

You can also update subscription information using Checkout.

Connect platforms and marketplaces

If you are operating a Connect platform or marketplace and create payments involving connected accounts, consider using the new version of Checkout’s server integration. Follow the instructions in the Connect guide to migrate your integration.

The following example demonstrates using the Checkout Sessions API to process a direct charge. Follow the Connect guide for details on how to create destination charges.

Before

With the legacy version of Checkout, you would collect card information from your customer on the client.

client.html

<form action="/purchase" method="POST">
  <script
    src="https://checkout.stripe.com/checkout.js"
    class="stripe-button"
    data-key="pk_test_TYooMQauvdEDq54NiTphI7jx"
    data-name="Food Marketplace"
    data-description="10 cucumbers from Roger's Farm"
    data-amount="2000">
  </script>
</form>

Next, you would send the resulting token or source to your server and charge it on behalf of the connected account.

Terminal

curl https://api.stripe.com/v1/charges \
  -u sk_test_4eC39HqLyjWDarjtT1zdp7dc
: \
  -d "source"="{{TOKEN_ID}}" \
  -d "description"="10 cucumbers from Roger\"s Farm" \
  -d "amount"=2000 \
  -d "currency"="usd" \
  -d "application_fee_amount"=200 \
  -H "Stripe-Account: {{CONNECTED_STRIPE_ACCOUNT_ID}}"

After

With the new version of Checkout, first create a Checkout Session on your server on behalf of the connected account.

Terminal

curl https://api.stripe.com/v1/checkout/sessions \
  -u sk_test_4eC39HqLyjWDarjtT1zdp7dc
: \
  -d "payment_method_types[]"="card" \
  -d "line_items[][price]"="{{PRICE_ID}}" \
  -d "line_items[][quantity]"=1 \
  -d "payment_intent_data[application_fee_amount]"=200 \
  -d "mode"="payment" \
  -d "success_url"="https://example.com/success" \
  -d "cancel_url"="https://example.com/cancel" \
  -H "Stripe-Account: {{CONNECTED_STRIPE_ACCOUNT_ID}}"

If you use one of our Client libraries, upgrade to the latest version of the library in order to use the Checkout Sessions API.

Next, pass the Session ID to your client and redirect your customer to Checkout to complete payment. Make sure to provide the connected account’s ID when initializing Stripe.js.

// Initialize Stripe.js with the same connected account ID used when creating
// the Checkout Session.
var stripe = Stripe('pk_test_TYooMQauvdEDq54NiTphI7jx', {
  stripeAccount: '{{CONNECTED_ACCOUNT_ID}}'
});
var checkoutButton = document.getElementById('checkout-button');

checkoutButton.addEventListener('click', function() {
  stripe.redirectToCheckout({
    // Make the id field from the Checkout Session creation API response
    // available to this file, so you can provide it as argument here
    // instead of the {{CHECKOUT_SESSION_ID}} placeholder.
    sessionId: '{{CHECKOUT_SESSION_ID}}'
  }).then(function (result) {
    // If `redirectToCheckout` fails due to a browser or network
    // error, display the localized error message to your customer
    // using `result.error.message`.
  });
});

The customer will be redirected to the success_url once they complete payment.

If you need to fulfill purchased goods or services after the payment, refer to Checkout Purchase Fulfillment.

Saving payment methods for future use

If you are providing services that don’t charge your customers immediately, see setting up future payments.

You may have used the legacy version of Checkout to create a token or source on the client, and passed it to your server to save for later use. The new version of Checkout’s server integration, however, reverses this flow. You first create a Session on your server, pass its ID to your client, redirect your customer to Checkout, who then gets redirected back to your application upon success.

Before

With the legacy version of Checkout, you would display the charge information and collect card information from your customer.

client.html

<form action="/subscribe" method="POST">
  <script
    src="https://checkout.stripe.com/checkout.js"
    class="stripe-button"
    data-key="pk_test_TYooMQauvdEDq54NiTphI7jx"
    data-name="Cleaning Service"
    data-description="Charged after your home is spotless"
    data-amount="2000">
  </script>
</form>

Next, you would send the resulting token or source to your server to eventually create a charge.

Terminal

curl https://api.stripe.com/v1/customers \
  -u sk_test_4eC39HqLyjWDarjtT1zdp7dc
: \
  -d "email"="customer@example.com" \
  -d "source"="{{STRIPE_TOKEN}}"
curl https://api.stripe.com/v1/charges \
  -u sk_test_4eC39HqLyjWDarjtT1zdp7dc
: \
  -d "customer"="{{CUSTOMER_ID}}" \
  -d "description"="Cleaning service" \
  -d "amount"="{{ORDER_AMOUNT}}" \
  -d "currency"="usd"

After

With the new version of Checkout, first create a Checkout Session on your server using setup mode.

Terminal

curl https://api.stripe.com/v1/checkout/sessions \
  -u sk_test_4eC39HqLyjWDarjtT1zdp7dc
: \
  -d "payment_method_types[]"="card" \
  -d "mode"="setup" \
  -d "success_url"="https://example.com/success?session_id={CHECKOUT_SESSION_ID}" \
  -d "cancel_url"="https://example.com/cancel"

If you use one of our Client libraries, upgrade to the latest version of the library in order to use the Checkout Sessions API.

Next, pass the Session ID to your client and redirect your customer to Checkout to gather payment method details.

var stripe = Stripe('pk_test_TYooMQauvdEDq54NiTphI7jx');
var checkoutButton = document.getElementById('checkout-button');

checkoutButton.addEventListener('click', function() {
  stripe.redirectToCheckout({
    // Make the id field from the Checkout Session creation API response
    // available to this file, so you can provide it as argument here
    // instead of the {{CHECKOUT_SESSION_ID}} placeholder.
    sessionId: '{{CHECKOUT_SESSION_ID}}'
  }).then(function (result) {
    // If `redirectToCheckout` fails due to a browser or network
    // error, display the localized error message to your customer
    // using `result.error.message`.
  });
});

The customer will be redirected to the success_url once they complete flow.

From there, you can retrieve the Setup Intent from the Checkout flow and use it to prepare your transaction.

Simple product catalog with fixed pricing

If you are selling products with fixed pricing (such as t-shirts or e-books), see the guide on one-time payments to learn how to generate a code snippet to add to your website.

You may have used the legacy version of Checkout to create a token or source on the client, and passed it to your server to create a charge. The new version of Checkout, however, automatically creates the payment for you, and no server integration is required.

Parameter conversion

The new version of Checkout supports most of the functionality of the legacy version of Checkout. However, the two versions do not share the same API. The table below maps parameters and configuration options between the legacy version and the new version.

The legacy Checkout reference documents parameters accepted by the previous version. For a full list of configuration options accepted by the new version of Checkout, see the Stripe.js reference and the API reference for Checkout Sessions.

Legacy version	New version	Integration tips
`allowRememberMe`	Not supported	The new version of Checkout does not support Remember Me. To reuse existing customers, we recommend specifying the `customer` parameter when creating a Checkout Session.
`amount`	Automatically calculated as the sum of amounts over all `line_items`. Client-only integration: Automatically calculated as the sum of amounts over all prices.	The total amount is the sum of the line items you pass to Checkout.
`billingAddress`	`Session.billing_address_collection` Client-only integration: `billingAddressCollection`	Checkout automatically collects the billing address when required for fraud-prevention or regulatory purposes. Set this parameter to `required` to always collect the billing address.
`billingAddress`	`Session.billing_address_collection` Client-only integration: `billingAddressCollection`	Checkout automatically collects the billing address when required for fraud-prevention or regulatory purposes. Set this parameter to `required` to always collect the billing address.
`closed`	`cancelUrl`	When a customer wants to close Checkout, they either close the browser tab or navigate to the `cancelUrl`.
`currency`	`Session.currency` Client-only integration: The price’s `currency`
`description`	`Session.line_items.description` or `product.description` Client-only integration: The price’s `product.description`	If you specify a price, Checkout displays an automatically computed description of how often payments occur. If you specify `Session.line_items`, Checkout displays the `name` for each line item.
`email`	`Session.customer_email` Client-only integration: `customerEmail`	If you already know your customer’s email, specify it here so they do not need to enter it again.
`image`	Business branding Upload your business logo or icon in the Dashboard. Product images Specify images for each line item with`product.images`	Checkout uses specific images for your business’s branding and for the products you are selling. Checkout displays your business logo by default and falls back to your business icon alongside your business name.
`key`	No longer a parameter passed to Checkout	Specify the publishable key when initializing Stripe.js as `Stripe('pk_...')` instead.
`locale`	`Session.locale` Client-only integration: `locale`	You can specify a supported locale when creating a Checkout Session.
`name`	`product.name` for prices specified in `Session.line_items` Client-only integration: The price’s `product.name`	If you specify a price, Checkout displays the name of the product to which the price belongs to the customer. If you specify `Session.line_items`, Checkout displays the `name` for each line item.
`panelLabel`	`submit_type`	Checkout automatically customizes the button text depending on the items you are selling. For one-time payments, use submit_type to customize the button text.
`shippingAddress`	`session.shipping_address_collection`	Collect shipping address information by passing an array of `allowed_countries` that you want to ship to.
`token` or `source`	`successUrl`	There is no longer a callback in JavaScript when the payment completes. As your customer is paying on a different page, set the `successUrl` to redirect your customer after they’ve completed payment.
`zipCode`	Automatically collected by Checkout	Checkout automatically collects the postal code when required for fraud-prevention or regulatory purposes.
