Getting Started

Sentry is designed to be very simple to get off the ground, yet powerful to grow into. If you have never used Sentry before, this tutorial will help you getting started.

Getting started with Sentry is a three step process:

  1. Sign up for an account
  2. Configure an SDK
  3. About the DSN

Configure an SDK

Sentry captures data by using an SDK within your application’s runtime. These are platform specific, and allow Sentry to have a deep understanding of both how your application works. In case your environment is very specific, you can also roll your own SDK using our document SDK API.

Popular integrations are:

For exact configuration for the integration consult the corresponding documentation. For all SDKs however, the basics are the same.

About the DSN

After you complete setting up a project in Sentry, you’ll be given a value which we call a DSN, or Data Source Name. It looks a lot like a standard URL, but it’s actually just a representation of the configuration required by the Sentry SDKs. It consists of a few pieces, including the protocol, public and secret keys, the server address, and the project identifier.

The DSN can be found in Sentry by navigation to Account -> Projects -> [Project Name] -> [Member Name]. Its template resembles the following:


If you use the Hosted Sentry and you are signed into your account, the documentation will refer to your actual DSNs and you can select the correct one, on the top right of this page for adjusting the examples for easy copy pasting:


It is composed of five important pieces:

  • The Protocol used. This can be one of the following: http or https.
  • The public and secret keys to authenticate the SDK.
  • The destination Sentry server.
  • The project ID which the authenticated user is bound to.

You’ll have a few options for plugging the DSN into the SDK, depending on what it supports. At the very least, most SDKs will allow you to set it up as the SENTRY_DSN environment variable or by passing it into the SDK’s constructor.

For example for the JavaScript SDK it works roughly like this:

import raven

Note: If you’re using Heroku, and you’ve added Hosted Sentry via the standard addon hooks, most SDKs will automatically pick up the SENTRY_DSN environment variable that we’ve already configured for you.

Next Steps

Now that you’ve got basic reporting setup, you’ll want to explore adding additional context to your data.
