API overview | AppSignal documentation

Base endpoint

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

https://appsignal.com/api

Responses

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.

Authentication

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

https://appsignal.com/api/[endpoint].json?token=personal_api_key

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

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

Applications

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:

/api/[app_id]/samples.json

The URL becomes:

https://appsignal.com/api/5114f7e38c5ce90000000011/samples.json?token=abc

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

https://appsignal.com/demo-organization/sites/5114f7e38c5ce90000000011
