# Update payment details Learn how to update the payment method used for future invoices. Use the following steps to create a Checkout page that collects your customer’s payment details and returns a Payment Method. Then use the Stripe REST APIs to update the payment method used for future *invoices* (Invoices are statements of amounts owed by a customer. They track the status of payments from draft through paid or otherwise finalized. Subscriptions automatically generate invoices, or you can manually create a one-off invoice). > This guide uses Checkout to update subscription payment methods. You can instead implement the [Billing customer portal](https://docs.stripe.com/customer-management.md) to provide a Stripe-hosted dashboard for your customers to manage their subscriptions and billing details. ## Set up Stripe [Server-side] First, you need a Stripe account. [Register now](https://dashboard.stripe.com/register). Use our official libraries for access to the Stripe API from your application: #### Ruby ```bash # Available as a gem sudo gem install stripe ``` ```ruby # If you use bundler, you can add this line to your Gemfile gem 'stripe' ``` ## Create a Checkout Session [Server-side] To create a setup mode Session, use the `mode` parameter with a value of `setup` when creating the Session. See the [Checkout Session API reference](https://docs.stripe.com/api/checkout/sessions/create.md) for a complete list of parameters that you can use for Session creation. Append the `{CHECKOUT_SESSION_ID}` template variable to the `success_url` to get access to the Session ID after your customer successfully completes a Checkout Session. Finally, use the [setup_intent_data.metadata](https://docs.stripe.com/api/checkout/sessions/create.md#create_checkout_session-setup_intent_data-metadata) dictionary to pass your customer’s existing Stripe `subscription_id` to the Checkout Session. Note that there other ways to pass this data to your server, but we’ll use metadata for this guide. #### curl ```bash curl https://api.stripe.com/v1/checkout/sessions \ -u <>: \ -d "payment_method_types[]"="card" \ -d "mode"="setup" \ -d "customer"="cus_FOsk5sbh3ZQpAU" \ -d "setup_intent_data[metadata][subscription_id]"="sub_8epEF0PuRhmltU" \ -d "success_url"="https://example.com/success?session_id={CHECKOUT_SESSION_ID}" ``` ## Redirect to Checkout [Client-side] Checkout relies on [Stripe.js](https://docs.stripe.com/payments/elements.md), Stripe’s foundational JavaScript library for building payment flows. #### HTML + JS To get started, include the following script tag on your website – always load it directly from **https://js.stripe.com**. You can’t include it in a bundle or host it yourself. See [Stripe samples](https://github.com/stripe-samples) for examples. ```javascript npm install @stripe/stripe-js ``` Next, create an instance of the [Stripe object](https://docs.stripe.com/js.md#stripe-function) by providing your publishable [API key](https://docs.stripe.com/keys.md) as the first parameter: ```javascript import {loadStripe} from '@stripe/stripe-js'; const stripe = await loadStripe('<>'); ``` To use Checkout on your website, you must add a snippet of code that includes the Session `id` from the [previous step](https://docs.stripe.com/payments/checkout/subscriptions/update-payment-details.md#create-checkout-session). When your customer is ready to save or update their payment method, call [redirectToCheckout](https://docs.stripe.com/js.md#stripe-redirect-to-checkout) and provide the Session `id` as a parameter. ```javascript const checkoutButton = document.getElementById('checkout-button'); checkoutButton.addEventListener('click', () => { 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}}' }) // If `redirectToCheckout` fails due to a browser or network // error, display the localized error message to your customer // using `error.message`. }); ``` #### React To get started, install the Stripe.js module. Always load Stripe.js directly from **https://js.stripe.com**. You can’t include it in a bundle or host it yourself. ```npm npm install @stripe/stripe-js ``` ### Add Stripe.js to your page Call `loadStripe` with your publishable key. It returns a `Promise` that resolves with the `Stripe` object once Stripe.js has loaded. When your customer is ready to save or update their payment method, call [redirectToCheckout](https://docs.stripe.com/js.md#stripe-redirect-to-checkout) and provide the Session `id` as a parameter. ```jsx import React from 'react'; import ReactDOM from 'react-dom'; import { loadStripe } from '@stripe/stripe-js'; // Make sure to call `loadStripe` outside of a component’s render to avoid // recreating the `Stripe` object on every render. const stripePromise = loadStripe('<>'); function App() { const handleClick = async (event) => { // Call your backend to create the Checkout session. const { sessionId } = await fetchCheckoutSession(); // When the customer clicks on the button, redirect them to Checkout. const stripe = await stripePromise; const { error } = await stripe.redirectToCheckout({ sessionId }); // If `redirectToCheckout` fails due to a browser or network // error, display the localized error message to your customer // using `error.message`. }; return ( ); } ReactDOM.render(, document.getElementById('root')); ``` This code is typically invoked from an event handler that triggers in response to an action taken by your customer, such as clicking on a payment button. ## Retrieve the Checkout Session [Server-side] After a customer successfully completes their Checkout Session, you need to retrieve the Session object. There are two ways to do this: - **Asynchronously**: Handle `checkout.session.completed` *webhooks* (A webhook is a real-time push notification sent to your application as a JSON payload through HTTPS requests), which contain a Session object. Learn more about [setting up webhooks](https://docs.stripe.com/webhooks.md). - **Synchronously**: Obtain the Session ID from the `success_url` when a user redirects back to your site. Use the Session ID to [retrieve](https://docs.stripe.com/api/checkout/sessions/retrieve.md) the Session object. ```curl curl https://api.stripe.com/v1/checkout/sessions/cs_test_MlZAaTXUMHjWZ7DcXjusJnDU4MxPalbtL5eYrmS2GKxqscDtpJq8QM0k \ -u "<>:" ``` The right choice depends on your tolerance for dropoff, as customers may not always reach the `success_url` after a successful payment. It’s possible for them close their browser tab before the redirect occurs. Handling webhooks prevents your integration from being susceptible to this form of dropoff. After you have retrieved the Session object, get the value of the `setup_intent` key, which is the ID for the SetupIntent created during the Checkout Session. A [SetupIntent](https://docs.stripe.com/payments/setup-intents.md) is an object used to set up the customer’s bank account information for future payments. Example `checkout.session.completed` payload: ```json { "id": "evt_1Ep24XHssDVaQm2PpwS19Yt0", "object": "event", "api_version": "2019-03-14", "created": 1561420781, "data": { "object": { "id": "cs_test_MlZAaTXUMHjWZ7DcXjusJnDU4MxPalbtL5eYrmS2GKxqscDtpJq8QM0k", "object": "checkout.session", "billing_address_collection": null, "client_reference_id": null, "customer": "cus_FOsk5sbh3ZQpAU", "customer_email": null, "display_items": [], "mode": "setup","setup_intent": "seti_1EzVO3HssDVaQm2PJjXHmLlM", "submit_type": null, "subscription": null, "success_url": "https://example.com/success" } }, "livemode": false, "pending_webhooks": 1, "request": { "id": null, "idempotency_key": null }, "type": "checkout.session.completed" } ``` Note the `setup_intent` ID for the next step. ## Retrieve the SetupIntent [Server-side] Using the `setup_intent` ID, retrieve the SetupIntent object using the [/v1/setup_intents/:id](https://docs.stripe.com/api/setup_intents/retrieve.md) endpoint. ```curl curl https://api.stripe.com/v1/setup_intents/seti_1EzVO3HssDVaQm2PJjXHmLlM \ -u "<>:" ``` Example response: ```json { "id": "seti_1EzVO3HssDVaQm2PJjXHmLlM", "object": "setup_intent", "application": null, "cancellation_reason": null, "client_secret": null, "created": 1561420781,"customer": "cus_FOsk5sbh3ZQpAU", "description": null, "last_setup_error": null, "livemode": false, "metadata": {"subscription_id": "sub_8epEF0PuRhmltU" }, "next_action": null, "on_behalf_of": null,"payment_method": "pm_1F0c9v2eZvKYlo2CJDeTrB4n", "payment_method_types": [ "card" ], "status": "succeeded", "usage": "off_session" } ``` Note the `customer` ID, `subscription_id`, and `payment_method` ID for the next steps. > If you’re requesting this information synchronously from the Stripe API (as opposed to handling webhooks), you can combine the previous step with this step by [expanding](https://docs.stripe.com/api/expanding_objects.md) the SetupIntent object in the request to the /v1/checkout/session endpoint. Doing this prevents you from having to make two network requests to access the newly created PaymentMethod ID. ## Set a default payment method [Server-side] There are two ways to ensure that a payment method is used for future invoices: - Set it as the Customer’s `invoice_settings.default_payment_method` - Set it as the Subscription’s `default_payment_method` Setting `invoice_settings.default_payment_method` on the Customer will cause all future invoices for that customer to be paid with the specified payment method. Setting `default_payment_method` on the Subscription will cause all future invoices for that subscription to be paid with the specified payment method, overriding any `invoice_settings.default_payment_method` set on the associated Customer. ### Set invoice_settings.default_payment_method on the Customer Using the customer ID and the PaymentMethod ID you retrieved, set the `invoice_settings.default_payment_method` for the Customer using the [/v1/customers/:id](https://docs.stripe.com/api/customers/update.md) endpoint. ```curl curl https://api.stripe.com/v1/customers/cus_FOsk5sbh3ZQpAU \ -u "<>:" \ -d "invoice_settings[default_payment_method]"=pm_1F0c9v2eZvKYlo2CJDeTrB4n ``` All future invoices for this customer will now charge the new PaymentMethod created with the setup mode Checkout Session. ### Set default_payment_method on the Subscription Using the subscription ID and the PaymentMethod ID you retrieved, set the `default_payment_method` for the subscription using the [/v1/subscriptions/:id](https://docs.stripe.com/api/subscriptions/update.md) endpoint. #### curl ```bash curl https://api.stripe.com/v1/subscriptions/sub_8epEF0PuRhmltU \ -u <>: \ -X "POST" \ -d "default_payment_method"="pm_1F0c9v2eZvKYlo2CJDeTrB4n" ``` All future invoices for this subscription will now charge the new PaymentMethod created with the setup mode Checkout Session, overriding any `invoice_settings.default_payment_method` set on the associated Customer. ## See also Congrats! You can now set a default payment method for future invoices. When testing your integration with your test API key, you can use a [test card number](https://docs.stripe.com/testing.md#cards) to ensure that it works correctly. - [Test Cards](https://docs.stripe.com/testing.md#cards)
