Chargebee Integration

This integration guide covers the full stack for working with Chargebee's billing platform, from framework-specific implementations like Laravel Cashier to REST API patterns. It emphasizes retrieval-led reasoning and provides practical code examples for webhook validation, customer management, and subscription handling across seven language SDKs. The skill includes security best practices (environment variables, credential rotation) and links to comprehensive reference docs for API schemas and error codes. What's useful here is the clear hierarchy: it pushes you toward framework integrations first, then SDKs, and only REST as a fallback. The webhook handler pattern with idempotency checks is production-ready out of the box.
