Read results
Understand reports, aggregate rows, and analyst readouts.
Fabric Experiments uses exposure-first attribution: conversions are interpreted in the context of who was exposed to which variant.
Local reports are available through the CLI:
fx report homepage-ctaHosted reports use the aggregate API:
GET /api/v1/orgs/{orgId}/experiments/{experimentId}/aggregate?metric=signupThe response includes one row per variant with exposure count, conversion count, conversion sum, failure count, and computed timestamp.
Agent readouts
When an experiment reaches a terminal state, audit-forward can dispatch the analyst workflow. The analyst fetches aggregate rows, asks the configured LLM for a short readout, and posts to Slack if FX_SLACK_WEBHOOK_URL is set.
