Filtering Out Third Party Browser Extension Errors | Sentry for JavaScript
docs.sentry.ioSaved November 26, 2025
Summary
Sentry for JavaScript allows filtering error events using SDK options like `ignoreErrors`, `allowUrls`, and `denyUrls` to block specific error messages or errors from certain domains.
The `beforeSend` callback provides custom logic to drop or modify events before they are sent, and the `thirdPartyErrorFilterIntegration` can filter errors from third-party code by marking application files with an application key. Transactions and spans can also be filtered using `ignoreTransactions`, `beforeSendTransaction`, and `beforeSendSpan` options.
