## Error Handling and Troubleshooting

This section provides comprehensive guidance on understanding and managing errors within the Stripe API. It covers various aspects of error handling, from basic concepts to advanced troubleshooting techniques, ensuring your integration is robust and resilient.

### Core Concepts and Best Practices

*   **Error Handling Overview:** Learn how to catch and respond to various types of Stripe errors, including declined payments, invalid data, and network problems. This page outlines the common error properties you'll encounter (code, message, param, etc.) and provides strategies for handling them gracefully.
*   **Advanced Error Handling:** Delve into the lower-level details of HTTP responses that represent errors. This includes understanding content errors (4xx), network errors, and server errors (5xx), and how idempotency plays a role in retrying failed requests.
*   **Error Codes:** Access a comprehensive list of Stripe error codes, along with descriptions and guidance on how to resolve them. This page also explains how to trigger specific error codes for testing purposes.
*   **Automated Testing:** Discover how to simulate API responses and errors using mock data to test your application's ability to handle various error scenarios, such as transaction declines.

### Specific Error Scenarios and Solutions

*   **Resolve Webhook Signature Verification Errors:** Troubleshoot common issues related to webhook signature verification, ensuring the integrity of events received from Stripe.
*   **Handle Webhook Event Generation Failures:** Learn how to manage rare instances where Stripe might fail to generate an Event object and how to recover using the `v2.core.health.event_generation_failure.resolved` event.
*   **Process Undelivered Webhook Events:** Understand how Stripe automatically resends undelivered webhook events and learn how to manually process them to speed up recovery.
*   **Handle Irrecoverable Webhook Events:** This page addresses situations where webhook events cannot be recovered and how Stripe notifies you of such failures.

### API Versioning and Error Handling

*   **API Upgrades:** Stay informed about changes and upgrades to the Stripe API, including understanding backward-compatible and non-backward-compatible changes, and how they might affect your integration.
*   **Set a Stripe API Version:** Learn how to target specific API versions for your requests, ensuring consistent behavior and compatibility, especially when dealing with potential breaking changes.
*   **Stripe versioning and support policy:** Understand Stripe's approach to API versioning and their support policy for different versions.

### Developer Tools for Error Management

*   **View API Request Logs:** Learn how to filter and inspect API request logs in the Developers Dashboard (or Workbench) to identify and troubleshoot issues.
*   **View Events and Event Object Payloads:** Understand how to view events triggered by your account and their associated payloads in the Developers Dashboard (or Workbench) for monitoring and debugging.
*   **Stripe Health Alerts:** Monitor the health of your API integrations with alerts and insights that notify you of issues affecting your payment flows or other Stripe product integrations.
*   **Health Alerts and Insights (Workbench):** Utilize Workbench to gain a consolidated view of critical and non-critical alerts affecting your Stripe payment processing, with actionable insights to improve integration health.
*   **Trigger Webhook Events with the Stripe CLI:** Learn how to simulate webhook events in a sandbox environment using the Stripe CLI for testing your webhook handlers.
