Bugsnag API

Bugsnag provides a simple JSON-based API to access information about your Bugsnag account, project and errors.

Bugsnag captures errors in real-time from your web, mobile and desktop applications, helping you to understand and resolve them as fast as possible. Create a free account to start capturing exceptions from your applications.



  • API access is over HTTPS using the endpoint
  • Data is sent and received using JSON
  • Timestamps are returned in ISO 8601 format: YYYY-MM-DDTHH:MM:SSZ


All requests to the Bugsnag API require authentication. To authenticate API requests you can either use your Bugsnag user credentials, or your account-wide auth token.

User Authentication

To access the Bugsnag API as a user, you can use your Bugsnag user credentials via Basic Authentication. Simply send the email address and password associated with the user:

curl -u

Account Authentication

Alternatively you can authenticate using your account auth token, which you can find on your Bugsnag "Account Settings" dashboard under the "API" section.

There are two ways to send the API token with requests, you can send the token in an Authorization header:

$ curl -H "Authorization: token YOUR-TOKEN-HERE"

Alternatively, you can authenticate using a parameter:

$ curl


Many API methods take optional parameters. For GET requests, any parameters not specified as a segment in the path can be passed as an HTTP query string parameter.

For POST, PATCH, and DELETE requests, parameters not included in the URL should be encoded as JSON with a Content-Type of ‘application/json’.


  • Sending invalid JSON will result in a 400 Bad Request response
  • Sending the wrong type of JSON values will result in a 400 Bad Request response
  • Trying to access the API without authenticating or with an invalid auth token will result in a 401 Unauthorized response
  • Trying to access resources which do not exist will result in a 404 Not Found response
  • Trying to access resources which you do not have access to will result in a 404 Not Found response, in order to avoid disclosing the existence of user data

Hypermedia URLs

All API resources may have one or more *_url properties linking to other resources. These are meant to provide explicit URLs so that API clients don’t need to construct URLs on their own. It is highly recommended that API clients use these. Doing so will make future upgrades of the API easier for developers.


Pagination info is included in the Link header. It is important to follow these Link header values instead of constructing your own URLs since the pagination method can differ between resources.

The URL for pagination is shown inside angled brackets, and the type of pagination link is described in the rel field:

Link: <>; rel="next"

The possible values for rel are:

  • next - Shows the URL for the next page of results
  • prev - Shows the URL for the previous page of results

Ruby Library

Check out the Bugsnag API Toolkit for Ruby for quick read/write access to the Bugsnag API from your Ruby applications.
