Change history

Optimizely Feature Experimentation logs actions performed for a project and for a flag, such as creating an event, modifying a rule, and adding and removing audiences. These actions are listed in the change history, which displays the record of user activity for each of your projects and flags. These actions are also available through webhooks, see Create a Webhook.

If an experiment starts to behave strangely or stops working correctly, you can troubleshoot by checking the change history to see which changes were made, when, and by which collaborator. The detailed change history creates an activity trail that provides additional security to individuals and teams with multiple collaborators.

See Change history in Feature Experimentation in the user documentation for what project-level and flag-level changes are tracked.

Project history

Each project's change history is available using the Feature Experimentation REST API and in the UI.

Access project history with the REST API

See the Retrieve changes for a project endpoint documentation for information on how to get a list of changes for a given project. You can use optional filters to refine the list of changes.
