Advanced implementation patterns and operational guidance — each guide is a complete, standalone reference for one part of the platform.

### Entitlement patterns

Boolean gates, limit checks, and metered entitlements — the verdict model, resolution layering, and caching-safe recheck triggers.

[Open guide](/docs/guides/entitlement-patterns)

### Caching

What the API marks as cacheable, what to cache yourself, and the invalidation events that keep both layers correct.

[Open guide](/docs/guides/caching)

### Metering best practices

Idempotent usage submission, batching high-frequency meters, threshold UX, and drift reconciliation.

[Open guide](/docs/guides/metering)

### Webhook verification and retries

Register endpoints, verify signatures against the raw body, and process retried deliveries idempotently.

[Open guide](/docs/guides/webhooks)

### Migration guide

URL-path versioning, deprecation detection, dual-read fallbacks, and staged rollouts for breaking changes.

[Open guide](/docs/guides/migration)

### Audit and trace

Propagate request IDs end-to-end and correlate API activity, webhook deliveries, and the audit log.

[Open guide](/docs/guides/audit-trace)

### Events & Webhook Explorer

Browse every webhook event type with sample payloads, and verify signatures interactively.

[Open guide](/docs/guides/events)

### Node SDK integration

Enriched decisions with reason codes, batch checks, caching with explicit degradation, credit reservations, and the SDK's two extension points.

[Open guide](/docs/guides/sdk-node)

### Clerk identity integration

Connect your Clerk instance to sync users and organizations as customers, then resolve sessions to customer ids on every request.

[Open guide](/docs/guides/clerk-identity)

### PostHog packaging analytics

Stream entitlement denials into your PostHog project — with explicit identity mapping, volume caps, and a preview of every event before anything is sent.

[Open guide](/docs/guides/posthog-analytics)

### OpenTelemetry visibility

One-line decision spans and bounded metrics on your existing OTel setup, with a deep link from every span to the exact evaluation record.
