An integration built with Stripe.js & Elements consists of the following steps:

1. Collect payment details on the client side
2. Attempt the payment on the server side
3. Handle the server response on the client side

Step 1: Collect payment details on the client side

Use the createPaymentMethod function, which collects the payment information and submits it directly to Stripe.

stripe.createToken(
// or stripe.createSource
  cardElement
).then(function(result) {
  if (result.error) {
    // Show error in payment form
  } else {
    // Send token.id to server
    fetch('/ajax/confirm_payment', {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json'
      },
      body: JSON.stringify({
        token_id: result.token.id
      })
    }).then(function(result) {
      // Handle server response (see Step 3)
      result.json().then(function(json) {
        handleServerResponse(json);
      })
    });
  }
});

stripe.createPaymentMethod(
  'card',
  cardElement
).then(function(result) {
  if (result.error) {
    // Show error in payment form
  } else {
    // Send paymentMethod.id to server
    fetch('/ajax/confirm_payment', {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json'
      },
      body: JSON.stringify({
        payment_method_id: result.paymentMethod.id
      })
    }).then(function(result) {
      // Handle server response (see Step 3)
      result.json().then(function(json) {
        handleServerResponse(json);
      })
    });
  }
});

const {token} =
  await stripe.createToken(
    cardElement
  );

// Send token.id to server
const response = await fetch(
  '/ajax/confirm_payment', {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json'
    },
    body: JSON.stringify({
      token_id: token.id
    })
  }
);

// Handle server response (see Step 3)
handleServerResponse(await response.json());

const {paymentMethod} =
  await stripe.createPaymentMethod(
    'card',
    cardElement
  );

// Send paymentMethod.id to server
const response = await fetch(
  '/ajax/confirm_payment', {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json'
    },
    body: JSON.stringify({
      payment_method_id: paymentMethod.id
    })
  }
);

// Handle server response (see Step 3)
await handleServerResponse(await response.json());

Step 2: Attempt the payment on the server side

In your existing integration, the final step is using tokenized payment information to create a charge on your server. With the Payment Intents API, this is sufficient if additional steps like 3D Secure authentication are not required. However, if some payments may require additional authentication, then additional code is required. Instead of creating a Charge, we’ll create a PaymentIntent.

curl https://api.stripe.com/v1/charges \
  -u sk_test_4eC39HqLyjWDarjtT1zdp7dc: \
  -d source="{{TOKEN_ID}}" \
  -d amount=1099 \
  -d currency=usd

curl https://api.stripe.com/v1/payment_intents \
  -u sk_test_4eC39HqLyjWDarjtT1zdp7dc: \
  -d payment_method="{{PAYMENT_METHOD_ID}}" \
  -d amount=1099 \
  -d currency=usd \
  -d confirmation_method=manual \
  -d confirm=true

charge = Stripe::Charge.create({
    source: data['token_id'],
    amount: 1099,
    currency: 'usd',
})

intent = Stripe::PaymentIntent.create({
    payment_method: data['payment_method_id'],
    amount: 1099,
    currency: 'usd',
    confirmation_method: 'manual',
    confirm: true,
})

return generate_payment_response(intent)

charge = stripe.Charge.create(
  source=data['token_id'],
  amount=1099,
  currency='usd',
)

intent = stripe.PaymentIntent.create(
  payment_method=data['payment_method_id'],
  amount=1099,
  currency='usd',
  confirmation_method='manual',
  confirm=True,
)

return generate_payment_response(intent)

$charge = \Stripe\Charge::create([
    'source' => $json_obj->token_id,
    'amount' => 1099,
    'currency' => 'usd',
]);

$intent = \Stripe\PaymentIntent::create([
    'payment_method' => $json_obj->payment_method_id,
    'amount' => 1099,
    'currency' => 'usd',
    'confirmation_method' => 'manual',
    'confirm' => true,
]);

generatePaymentResponse($intent);

Map<String, Object> chargeParams = new HashMap<String, Object>();
chargeParams.put("amount", 1099);
chargeParams.put("currency", "usd");
chargeParams.put("source", request.token_id);
Charge.create(chargeParams);

Map<String, Object> createPaymentIntentParams = new HashMap<String, Object>();
createPaymentIntentParams.put("currency", "usd");
createPaymentIntentParams.put("amount", 1099);
createPaymentIntentParams.put("confirm", true);
createPaymentIntentParams.put("confirmation_method", "manual");
createPaymentIntentParams.put("payment_method", request.paymentMethodId);
intent = PaymentIntent.create(createPaymentIntentParams);

Map<String, Object> responseData = generatePaymentResponse(response, intent);

(async () => {
  const charge = await stripe.charges.create({
    amount: 1099,
    currency: 'usd',
    source: request.body.token_id,
  });
})();

(async () => {
  const intent = await stripe.paymentIntents.create({
    payment_method: request.body.payment_method_id,
    amount: 1099,
    currency: 'usd',
    confirmation_method: 'manual',
    confirm: true
  });

  generate_payment_response(intent));
})();

params := &stripe.ChargeParams{
  Amount: stripe.Int64(1099),
  Currency: stripe.String(string(stripe.CurrencyUSD)),
}
params.SetSource(*paymentRequest.TokenId)
ch, _ := charge.New(params)

params := &stripe.PaymentIntentParams{
  PaymentMethod: stripe.String(*paymentRequest.PaymentMethodId),
  Amount: stripe.Int64(1099),
  Currency: stripe.String(string(stripe.CurrencyUSD)),
  Confirm: stripe.Bool(true),
  ConfirmationMethod: stripe.String(string(stripe.PaymentIntentConfirmationMethodManual)),
}

intent, err = paymentintent.New(params)

var options = new ChargeCreateOptions
{
    Amount = 999,
    Currency = "usd",
    Source = request.tokenId,
};
var service = new ChargeService();
Charge charge = service.Create(options);

var service = new PaymentIntentService();
var options = new PaymentIntentCreateOptions
{
    PaymentMethodId = request.PaymentMethodId,
    Amount = 1099,
    Currency = "usd",
    ConfirmationMethod = "manual",
    Confirm = true,
};
paymentIntent = service.Create(options);

Check the PaymentIntent status with generate_payment_response. If the payment requires additional actions such as 3D Secure authentication, the PaymentIntent’s status will be set to requires_action. If the payment is successful, then the status is set to succeeded and the payment is complete. If the payment failed, the status is set to requires_payment_method.

You can see a full server implementation using generate_payment_response in our manual confirmation quickstart.

      && intent.getNextAction().getType().equals("use_stripe_sdk")) {
    responseData.put("requires_action", true);

        return StatusCode(500, new { error = "Invalid PaymentIntent status" });
    }
}

Step 3: Handle the server response on the client side

On the client side, handle the new case when additional action is required with stripe.handleCardAction. After it completes without error, the PaymentIntent now has a status of requires_confirmation. Send the ID of the PaymentIntent to the same server endpoint to confirm the payment again.

function handleServerResponse(response) {
  if (response.error) {
    // Show error on payment form
  } else {
    // Show success message
  }
}

function handleServerResponse(response) {
  if (response.error) {
    // Show error from server on payment form
  } else if (response.requires_action) {
    // Use Stripe.js to handle required card action
    handleAction(response);
  } else {
    // Show success message
  }
}

function handleAction(response) {
  stripe.handleCardAction(
    response.payment_intent_client_secret
  ).then(function(result) {
    if (result.error) {
      // Show error in payment form
    } else {
      // The card action has been handled
      // The PaymentIntent can be confirmed again on the server
      fetch('/ajax/confirm_payment', {
        method: 'POST',
        headers: {
          'Content-Type': 'application/json'
        },
        body: JSON.stringify({
          payment_intent_id: result.paymentIntent.id
        })
      }).then(function(confirmResult) {
        return confirmResult.json();
      }).then(handleServerResponse);
    }
  });
}

function handleServerResponse(response) {
  if (response.error) {
    // Show error on payment form
  } else {
    // Show success message
  }
}

async function handleServerResponse(response) {
  if (response.error) {
    // Show error from server on payment form
  } else if (response.requires_action) {
    // Use Stripe.js to handle required card action
    await handleAction(response);
  } else {
    // Show success message
  }
}

async function handleAction(response) {
  const {
    error: errorAction,
    paymentIntent
  } = await stripe.handleCardAction(
    response.payment_intent_client_secret
  );

  if (errorAction) {
    // Show error from Stripe.js in payment form
  } else {
    const response = await fetch(
      '/ajax/confirm_payment', {
        method: 'POST',
        headers: {
          'Content-Type': 'application/json'
        },
        body: JSON.stringify({
          payment_intent_id: paymentIntent.id
        })
      }
    );

    // Step 3: handle server response
    handleServerResponse(await response.json());
  }
}

Now that you have migrated, use the test cards in the following section to verify your upgraded integration handles 3D Secure authentication.

The Stripe.js Payment Request Button works with the Payment Intents API by using the PaymentMethod obtained in a traditional PaymentRequest integration and attaching it to a PaymentIntent.

An integration built with the Payment Request API consists of the following steps:

1. Collect payment details on the client side
2. Attempt the payment on the server side
3. Handle the server response on the client side

Step 1: Collect payment details on the client side

Listen for the PaymentRequest object’s paymentmethod event, which provides a paymentMethod and a callback function that you can use to indicate when the payment process is complete.

paymentRequest.on('token', function(ev) {
  // Send token to server
  fetch(
    '/ajax/confirm_payment', {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json'
      },
      body: JSON.stringify({
        token_id: ev.token.id
      })
    }
  ).then(function(response) {
    // Handle server response (see Step 3)
    response.json().then(function(json) {
      handleServerResponse(json);
    });
  });
});

paymentRequest.on('paymentmethod', function(ev) {
  // Send paymentMethod to server
  fetch(
    '/ajax/confirm_payment', {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json'
      },
      body: JSON.stringify({
        payment_method_id: ev.paymentMethod.id
      })
    }
  ).then(function(response) {
    // Handle server response (see Step 3)
    response.json().then(function(json) {
      handleServerResponse(json);
    });
  });
});

paymentRequest.on('token',
  async ({token, complete}) => {
    // Send token to server
    const response = await fetch(
      '/ajax/confirm_payment', {
        method: 'POST',
        headers: {
          'Content-Type': 'application/json'
        },
        body: JSON.stringify({
          token_id: token.id
        })
      }
    );

    // Handle server response (see Step 3)
    handleServerResponse(await response.json(), complete);
});

paymentRequest.on('paymentmethod',
  async ({paymentMethod, complete}) => {
    // Send paymentMethod to server
    const response = await fetch(
      '/ajax/confirm_payment', {
        method: 'POST',
        headers: {
          'Content-Type': 'application/json'
        },
        body: JSON.stringify({
          payment_method_id: paymentMethod.id
        })
      }
    );

    // Step 3: handle server response
    await handleServerResponse(await response.json(), complete);
});

Step 2: Attempt the payment on the server side

In your existing integration, the final step is using tokenized payment information to create a charge on your server. With the Payment Intents API, this is sufficient if additional steps like 3D Secure authentication are not required. However, if some payments may require additional authentication, then additional code is required. Instead of creating a Charge, create a PaymentIntent.

Step 3: Handle the server response on the client side

On the client side, handle the new case when additional action is required with stripe.handleCardAction. After it completes without error, the PaymentIntent now has a status of requires_confirmation. Send the ID of the PaymentIntent to the same server endpoint to confirm the payment again.

function handleServerResponse(response, complete) {
  if (response.error) {
    complete('fail');
  } else {
    complete('success');
  }
}

function handleServerResponse(response, complete) {
  if (response.error) {
    complete('fail');
  } else if (response.requires_action) {
    complete('success');
    handleAction(response);
  } else {
    complete('success');
  }
}

function handleAction(response) {
  stripe.handleCardAction(
    response.payment_intent_client_secret
  ).then(function(result) {
    if (result.error) {
      // Show error in payment form
    } else {
      // The card action has been handled
      // The PaymentIntent can be confirmed again on the server
      fetch('/ajax/confirm_payment', {
        method: 'POST',
        headers: {
          'Content-Type': 'application/json'
        },
        body: JSON.stringify({
          payment_intent_id: result.paymentIntent.id
        })
      }).then(function(confirmResult) {
        return confirmResult.json();
      }).then(handleServerResponse);
    }
  });
}

function handleServerResponse(response, complete) {
  if (response.error) {
    complete('fail');
  } else {
    complete('success');
  }
}

async function handleServerResponse(response, complete) {
  if (response.error) {
    complete('fail');
  } else if (response.requires_action) {
    complete('success');
    await handleAction(response);
  } else {
    complete('success');
  }
}

async function handleAction(response) {
  const {
    error: errorAction,
    paymentIntent
  } = await stripe.handleCardAction(
    response.payment_intent_client_secret
  );

  if (errorAction) {
    // Show error from Stripe.js in payment form
  } else {
    const response = await fetch(
      '/ajax/confirm_payment', {
        method: 'POST',
        headers: {
          'Content-Type': 'application/json'
        },
        body: JSON.stringify({
          payment_intent_id: paymentIntent.id
        })
      }
    );

    // Step 3: handle server response
    handleServerResponse(await response.json());
  }
}

Now that you have migrated, use the test cards in the following section to verify your upgraded integration handles 3D Secure authentication.

If you’re using the legacy version of Checkout, upgrade to the new version of Checkout—the fastest way to accept payments with Stripe. With it, you can accept one-time payments and subscriptions. You can also use Checkout without using the Stripe API on your server. Follow the Checkout migration guide to migrate your existing integration.

If you prefer to build your own checkout flow instead, switch to Elements. Assuming you have upgraded to Elements, you can build a Payment Intents API integration following the Payment Intents API migration guide for Elements.

If you are preparing for Strong Customer Authentication (SCA) and need to migrate to the Payment Intents API without updating how you collect payment details, follow this guide.

Step 1: Collect payment details on the client side

To use the Payment Intents API with the legacy version of Checkout (Custom integration), first add the Stripe.js v3 script tag to your website and instantiate its Stripe object:

<script src="https://js.stripe.com/v3/"></script>

var stripe = Stripe('pk_test_TYooMQauvdEDq54NiTphI7jx');

Then, collect payment details in the same manner as your existing integration using the legacy version of Checkout.

Before

After

StripeCheckout.configure({
  // ...configuration
  token: function(token) {
    // Send token.id to your server
    fetch(
      '/ajax/confirm_payment', {
        method: 'POST',
        headers: {
          'Content-Type': 'application/json'
        },
        body: JSON.stringify({
          token_id: token.id
        })
      }
    ).then(function(response) {
      // Handle server response (see Step 3)
      response.json().then(function(json) {
        handleServerResponse(json);
      });
    });
   },
 });

Same as before

Before

After

StripeCheckout.configure({
   // ...configuration
   token: async (token) => {
     // Send token.id to your server
     const response = await fetch(
      '/ajax/confirm_payment', {
        method: 'POST',
        headers: {
          'Content-Type': 'application/json'
        },
        body: JSON.stringify({
          token_id: token.id
        })
      }
    );

    // Handle server response (see Step 3)
    handleServerResponse(await response.json());
   },
 });

Same as before

Step 2: Attempt payment on the server side

When attempting the payment on the server, pass the token when creating the PaymentIntent.

Check the PaymentIntent status with generate_payment_response. If the payment requires additional actions such as 3D Secure authentication, the PaymentIntent’s status will be set to requires_action. If the payment is successful, then the status is set to succeeded and the payment is complete. If the payment failed, the status is set to requires_payment_method.

Now that you have migrated, use the test cards in the following section to verify your upgraded integration handles 3D Secure authentication.

In order to upgrade an existing Stripe.js v2 integration to use the Payment Intents API, first update your integration to collect payment information with Elements. Elements provides pre-built UI components and offers simple PCI compliance with SAQ A reporting.

After you have upgraded to Elements, you can build a Payment Intents API integration following the Payment Intents API migration guide for Elements.

If you are preparing for Strong Customer Authentication (SCA) and need to migrate to the Payment Intents API without updating how you collect payment details, follow this guide.

Step 1: Collect payment details on the client side

To use the Payment Intents API with the Stripe.js v2, first add the Stripe.js v3 script tag to your website and instantiate its Stripe object:

<script src="https://js.stripe.com/v3/"></script>

var stripe = Stripe('pk_test_TYooMQauvdEDq54NiTphI7jx');

Then, collect payment details in the same manner as your existing integration.

Before

After

Stripe.card.createToken({
  number: $('.card-number').val(),
  cvc: $('.card-cvc').val(),
  exp_month: $('.card-expiry-month').val(),
  exp_year: $('.card-expiry-year').val(),
  address_zip: $('.address_zip').val()
}, function(status, token) {
  // Send token.id to your server
  fetch(
    '/ajax/confirm_payment', {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json'
      },
      body: JSON.stringify({
        token_id: token.id
      })
    }
  ).then(function(response) {
    // Handle server response (see Step 3)
    response.json().then(function(json) {
      handleServerResponse(json);
    });
  });
});

Same as before

Before

After

Stripe.card.createToken({
  number: $('.card-number').val(),
  cvc: $('.card-cvc').val(),
  exp_month: $('.card-expiry-month').val(),
  exp_year: $('.card-expiry-year').val(),
  address_zip: $('.address_zip').val()
}, (status, token) => {
  // Send token.id to your server
  const response = await fetch(
    '/ajax/confirm_payment', {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json'
      },
      body: JSON.stringify({
        token_id: token.id
      })
    }
  );

  // Handle server response (see Step 3)
  handleServerResponse(await response.json());
});

Same as before

Step 2: Attempt payment on the server side

When attempting the payment on the server, pass the token when creating the PaymentIntent.

Check the PaymentIntent status with generate_payment_response. If the payment requires additional actions such as 3D Secure authentication, the PaymentIntent’s status will be set to requires_action. If the payment is successful, then the status is set to succeeded and the payment is complete. If the payment failed, the status is set to requires_payment_method.

You can see a full server implementation using generate_payment_response in our manual confirmation quickstart.

Step 3: Handle the server response on the client side

On the client side, handle the new case when additional action is required with stripe.handleCardAction. After it completes without error, the PaymentIntent now has a status of requires_confirmation. Send the ID of the PaymentIntent to the same server endpoint to confirm the payment again.

Before

After

function handleServerResponse(response) {
  if (response.error) {
    // Show error on payment form
  } else {
    // Show success message
  }
}

function handleServerResponse(response) {
  if (response.error) {
    // Show error from server on payment form
  } else if (response.requires_action) {
    // Use Stripe.js to handle required card action
    handleAction(response);
  } else {
    // Show success message
  }
}

function handleAction(response) {
  stripe.handleCardAction(
    response.payment_intent_client_secret
  ).then(function(result) {
    if (result.error) {
      // Show error in payment form
    } else {
      // The card action has been handled
      // The PaymentIntent can be confirmed again on the server
      fetch('/ajax/confirm_payment', {
        method: 'POST',
        headers: {
          'Content-Type': 'application/json'
        },
        body: JSON.stringify({
          payment_intent_id: result.paymentIntent.id
        })
      }).then(function(confirmResult) {
        return confirmResult.json();
      }).then(handleServerResponse);
    }
  });
}

    // Show success message
  }
}

async function handleServerResponse(response) {
  if (response.error) {
    // Show error from server on payment form
  } else if (response.requires_action) {
    // Use Stripe.js to handle required card action
    await handleAction(response);
  } else {
    // Show success message
  }
}

async function handleAction(response) {
  const {
    error: errorAction,
    paymentIntent
  } = await stripe.handleCardAction(
    response.payment_intent_client_secret
  );

  if (errorAction) {
    // Show error from Stripe.js in payment form
  } else {
    const response = await fetch(

        method: 'POST',
        headers: {
          'Content-Type': 'application/json'
        },
        body: JSON.stringify({
          payment_intent_id: paymentIntent.id
        })
      }
    );

    // Step 3: handle server response
    handleServerResponse(await response.json());
  }
}

Now that you have migrated, use the test cards in the following section to verify your upgraded integration handles 3D Secure authentication.

For saving cards in the checkout flow, there are two differences between your existing integration and a Payment Intents API integration with manual confirmation.

On the client side, use the createPaymentMethod function instead of createToken or createSource.

stripe.createToken(
// or stripe.createSource
  cardElement
).then(function(result) {
  if (result.error) {
    // Display result.error.message in UI
  } else {
    // Send result.token to server
  }
});

stripe.createPaymentMethod(
  'card',
  cardElement
).then(function(result) {
  if (result.error) {
    // Display result.error.message in UI
  } else {
    // The PaymentMethod has successfully
    // been created
  }
});

const {token, error} =
  await stripe.createToken(
  // or stripe.createSource
    cardElement
  );
if (error) {
  // Display error.message in UI
} else {
  // Send token to server
}

const {paymentMethod, error} =
  await stripe.createPaymentMethod(
    'card',
    cardElement
  );
if (error) {
  // Display error.message in UI
} else {
  // The PaymentMethod has successfully
  // been created
}

On the server side, use the save_payment_method parameter on the PaymentIntent to attach the provided payment method to the customer. Your existing integration requires a separate API call to save the payment method—this is no longer necessary.

For saving cards outside the checkout flow, there are two differences between your existing integration and a Payment Methods API integration.

On the client side, use the createPaymentMethod function instead of createToken or createSource.

stripe.createToken(
// or stripe.createSource
  cardElement
).then(function(token) {
  // Send token to server
});

stripe.createPaymentMethod(
  'card',
  cardElement
).then(function(result) {
  if (result.error) {
    // Display error.message in your UI.
  } else {
    // The PaymentMethod has successfully been created
  }
});

const {token} =
  await stripe.createToken(
  // or stripe.createSource
    cardElement
  );

const {paymentMethod} =
  await stripe.createPaymentMethod(
    'card',
    cardElement
  );

On the server side, attach the payment method to the Customer object using the Payment Methods API instead of the Customers API.

curl https://api.stripe.com/v1/customers/{{CUSTOMER_ID}}/sources \
  -u sk_test_4eC39HqLyjWDarjtT1zdp7dc: \
  -d source="{{TOKEN_FROM_STEP_1}}"

card = Stripe::Customer.create_source(

When paying with a previously saved payment method, you must specify both the ID of the Customer and the ID of the previously saved Card, Source, or PaymentMethod. Previously, the default source on the customer is used if one was not provided. You must now explicitly pass in the desired payment method.
