Agent Notifications

Agent provides an endpoint that sends notifications to subscribers via Server-Sent Events. This is Agent's equivalent of Notification Listeners found in Optimizely SDKs.

For details on the notification types, what causes them to be triggered, and the data they provide, see the Set up notification listener documentation in Go.

Configuration

By default, the notifications endpoint is disabled. To enable it, change config.yaml:

# config.yaml
api:
    enableNotifications: true

Or, enable it by setting an environment variable:

# set an env. variable
export OPTIMIZELY_API_ENABLENOTIFICATIONS=1

Usage

Send a GET request to /v1/notifications/event-stream to subscribe:

curl -N -H "Accept:text/event-stream" -H "X-Optimizely-Sdk-Key:<YOUR SDK KEY>"\
  http://localhost:8080/v1/notifications/event-stream

This connection will remain open, and any notifications triggered by other requests received by Agent are pushed as events to this stream. Try sending requests to /v1/activate or /v1/track to see notifications being triggered.

Filtering

To subscribe only to a particular category of notifications, add a filter query parameter. For example, to subscribe only to Decision notifications:

# filter on decision notifications
curl -N -H "Accept:text/event-stream" -H "X-Optimizely-Sdk-Key:<YOUR SDK KEY>"\
  http://localhost:8080/v1/notifications/event-stream?filter=decision
