Official Sentry SDK for Symfony

This is the official Symfony SDK for Sentry.

Getting Started

Using this sentry-symfony SDK provides you with the following benefits:

  • Quickly integrate and configure Sentry for your Symfony app
  • Out of the box, each event will contain the following data by default
    • The currently authenticated user
    • The Symfony environment


To install the SDK you will need to be using Composer in your project. To install it please see the docs.

composer require sentry/sentry-symfony

If you're using the Symfony Flex Composer plugin, you might encounter a message similar to this:

The recipe for this package comes from the "contrib" repository, which is open to community contributions.
Review the recipe at

Do you want to execute this recipe?

Just type y, press return, and the procedure will continue.

Caution: Due to a bug in the SensioFrameworkExtra bundle, affecting version 6.0 and below, you might run into a missing Nyholm\Psr7\Factory\Psr17Factory::class error while executing the commands mentioned above. If you are not using the PSR-7 bridge, you can work around this issue by changing the configuration of the bundle as follows:

      enabled: false

For more details about the issue see sensiolabs/SensioFrameworkExtraBundle#710.

Enable the Bundle

If you installed the package using the Flex recipe, the bundle will be automatically enabled. Otherwise, enable it by adding it to the list of registered bundles in the Kernel.php file of your project:

class AppKernel extends \Symfony\Component\HttpKernel\Kernel
    public function registerBundles(): array
        return [
            // ...
            new \Sentry\SentryBundle\SentryBundle(),

    // ...

The bundle will be enabled in all environments by default. To enable event reporting, you'll need to add a DSN (see the next step).


Add the Sentry DSN of your project. If you're using Symfony 3.4, add the DSN to your app/config/config_prod.yml file. For Symfony 4 or newer, add the DSN to your config/packages/sentry.yaml file.

Keep in mind that by leaving the dsn value empty (or undeclared), you will disable Sentry's event reporting.

    dsn: ""
        enabled: true # flushes Sentry messages at the end of each message handling
        capture_soft_fails: true # captures exceptions marked for retry too
        environment: '%kernel.environment%'
        release: '%env(VERSION)%' #your app version

The parameter options allows to fine-tune exceptions. To discover more options, please refer to the Unified APIs options and the PHP specific ones.

Optional: use custom HTTP factory/transport

Since the SDK 2.0 uses HTTPlug to remain transport-agnostic, you need to install two packages that provide php-http/async-client-implementation and psr/http-message-implementation.

This bundle depends on sentry/sdk, which is a metapackage that already solves this need, requiring our suggested HTTP packages: the Symfony HTTP client (symfony/http-client) and Guzzle's message factories (http-interop/http-factory-guzzle).

If you want to use a different HTTP client or message factory, you can override the sentry/sdk package by adding the following to your composer.json after the require section:

    "replace": {
        "sentry/sdk": "*"

For example when you want to use Guzzle's components:

composer require php-http/guzzle6-adapter guzzlehttp/psr7

If you don't have a compatible HTTP client and/or message factory implementation installed php-http/discovery will try to install it for you using a Composer plugin.

Maintained versions

  • 4.x is actively maintained and developed on the master branch, and uses Sentry SDK 3.0;
  • 3.x is supported only for fixes and uses Sentry SDK 2.0;
  • 2.x is no longer maintained; from this version onwards it requires Symfony 3+ and PHP 7.1+;
  • 1.x is no longer maintained; you can use it for Symfony < 2.8 and PHP 5.6/7.0;
  • 0.8.x is no longer maintained.

Upgrading to 4.0

The 4.0 version of the bundle uses the newest version (3.x) of the underlying Sentry SDK. If you need to migrate from previous versions, please check the document.

Custom serializers

The option class_serializers can be used to send customized objects serialization.

            YourValueObject: 'ValueObjectSerializer'

Several serializers can be added and the serializable check is done by using the instanceof type operator. The serializer must implement the __invoke method, which needs to return an array, containing the information that should be send to Sentry. The class name is always sent by default.

Serializer example:

final class ValueObjectSerializer
    public function __invoke(YourValueObject $vo): array
        return [
            'value' => $vo->value()
