API Endpoints

Authorization is done with an oauth token from the FxA Oauth Server

GET /v1/{ app }/experiments.bundle.js

Returns a javascipt bundle for running experiments locally.

POST /v1/{ app }/variables

Returns an object mapping configuration variables to values based on currently running experiments. Only variables affected by experiments are returned therefore the result may be an empty object.

Parameters

• subject - (optional) an object with subject attributes used by experiments
• enrolled - (optional) an array of experiment names that this subject is enrolled in

Authorization is optional. When used the service stores which experiments the user is enrolled in, so the enrolled parameter is not required.

The user id from the oauth token is made available to experiments automatically if the request is authenticated, so it does not need to be set in the subject
