Import name: sentry_sdk.integrations.flask.FlaskIntegration

The Flask integration adds support for the Flask Web Framework.

  1. Install sentry-sdk from PyPI with the flask extra:

     $ pip install --upgrade sentry-sdk[flask]==0.4.3
  2. To configure the SDK, initialize it with the integration before or after your app has been initialized:

    import sentry_sdk
    from sentry_sdk.integrations.flask import FlaskIntegration
    app = Flask(__name__)


  • The Flask integration will be installed for all of your apps. It hooks into Flaskā€™s signals, not anything on the app object.

  • A bit of data is attached to each event:

    • Personally identifiable information (such as user ids, usernames, cookies, authorization headers, ip addresses) is excluded unless send_default_pii is set to true.

    • Request data is attached to all events.

    • If you have Flask-Login installed and configured, user data is attached to the event.

  • All exceptions leading to a Internal Server Error are reported.

  • Logging with app.logger or really any logger will create breadcrumbs when the Logging integration is enabled (done by default).
