API overview

Base endpoint

The base endpoint for all API calls is /api on the domain.



The response type supported by the AppSignal API is JSON. On some endpoints JSONP is also supported.

Make sure all requests to endpoints end with the .json extension so no URLs will have to be updated in the future.


Parameter Type Description
token string, required Your personal API key.

All requests to AppSignal API endpoints require a personal API token given as an URL query parameter for authentication.


(Replace [endpoint] with the endpoint you need.)

Your personal API key can be found on the personal settings screen.


Parameter Type Description
app_id string, required Application id

All endpoints provided by our API are scoped on application-level, not on organization-level (more than one application).

For the API to know what data to return from which application the application id needs to be provided in the endpoint URL.

For example, given this string in the API documentation:


The URL becomes:


The app_id for an application can be found in the URL of the when an application is opened. For legacy reasons the URL will mention /sites rather than /applications. The id that follows is your application id.
