Stripe Payments API

The Payment Intents API is the modern way to handle payments, designed to manage the entire lifecycle of a transaction, including complex authentication steps like 3D Secure. The older Charges API primarily handles one-time payments but lacks the robust flow needed to satisfy European Strong Customer Authentication regulations. Stripe now strongly recommends using Payment Intents for all new integrations.

You can simulate various failure scenarios in the Stripe Payments API by using specific test card numbers provided in their documentation. For example, using the card number 4000 0000 0000 0002 will trigger a generic decline, forcing your application's error handling to kick in. This allows you to verify that your UI correctly informs the user when a payment fails.

Webhooks are HTTP endpoints that Stripe calls to notify your application about events, such as a successful payment or a refund. When a payment is processed offline or asynchronously, your server receives an event, allowing you to fulfill the customer's order securely. You must verify the webhook signatures to ensure the request actually came from Stripe.

Yes, the Stripe Payments API provides seamless integration for digital wallets like Apple Pay and Google Pay through the Payment Request Button Element. This allows customers to checkout quickly using their stored billing information without manually entering their card details. Implementing these wallets can significantly increase conversion rates, especially on mobile devices.
