# Sentry for Fastify

[Fastify](https://fastify.dev/) doesn't need its own Sentry SDK. Set up Sentry for the runtime your app runs on, and the SDK instruments Fastify automatically: `fastifyIntegration` captures errors from your routes and hooks, and creates spans for incoming requests when tracing is enabled.

## [Customize Error Capturing](https://docs.sentry.io/platforms/javascript/guides/fastify.md#customize-error-capturing)

Errors with a 3xx or 4xx status code are skipped. To change which errors are captured, pass a `shouldHandleError` callback to `fastifyIntegration()`. See the [Fastify integration](https://docs.sentry.io/platforms/javascript/guides/node/configuration/integrations/fastify.md#shouldhandleerror) for all options.
