Get started with Experimentation Events Export
Amazon S3 export is being decommissioned.
Starting November 30, 2026, Optimizely will stop delivering Experimentation Events Export data through Amazon S3. After this date, use Google Cloud Storage (GCS) to download your data.
GCS is available to all customers today and contains data from June 2026 onward.
To migrate, use the Authentication API Authentication API to exchange your Personal Access Token for GCP credentials, then read your data with the Google Cloud CLI (cloud storage).
Data from before June 2026 is available only in Amazon S3.
Optimizely Experimentation Events Export delivers raw decision and conversion events from your experiments, so you can run analysis or downstream processing outside Optimizely.
Access the data in whichever form fits your workflow:

The oevents CLI supports Amazon S3 only, which is being decommissioned on November 16, 2026. For GCS, use the Authentication API with the Google Cloud CLI.
