Updating your integration to support Strong Customer Authentication consists of the following steps:
- Identify your payment flow
- Determine your integration path
- Implement the new integration path
- Test dynamic authentication
Start updating your integration today. After your integration is live, 3D Secure authentication is displayed when required by SCA.
1. Identify your payment flow
First, identify the payment flow that most closely matches your business. Read more about various flows to design a payment flow for SCA.
|Example Business Scenario
|You charge the customer’s cards immediately after they confirm payment.
|You charge the customer on a recurring basis.
|Gym membership for fixed-amount recurring charges, or utility bill for metered billing
|Payments with separate authorize and capture within 7 days.
|You separately authorize and capture card payments within 7 days after the customer confirms payment.
|Payment captured more than seven days after authorization.
|You charge the customer’s card more than 7 days after they submit payment details.
|Crowdfunding, or car rental if final amount may change.
|Other off-session payments
|You save the customer’s cards and charge some time later when the customer is not available to complete authentication.
2. Determine your integration path
Choose an integration option based on your payment flow below:
3. Implement the new integration path
You need to make server-side and client-side changes.
Follow the migration guide to learn how to migrate from the Charges API to the Payment Intents API.
In order to dynamically display 3D Secure authentication for card payments, client-side changes are also required alongside server-side changes for the Payment Intents API.
Using Stripe Checkout
4. Test dynamic authentication
To verify that your updated integration handles 3D Secure correctly, be sure to test both successful and unsuccessful authentication flows, using the regulatory test cards.
By default, 3D Secure authentication is only shown when the customer’s bank requires it, so your checkout conversion isn’t negatively affected. As of September 14, 2019, your updated integration displays the 3D Secure authentication flow automatically whenever required by SCA.
