Overview of the Optimizely Experimentation REST API.

Overview and how to get started using the Optimizely Experimentation's REST API.


Optimizely's REST API lets you create and manage Optimizely projects and experiments and analyze results from other applications.

For example, Optimizely solutions partners and technology partners use the REST API to:

  • Create Optimizely audiences based on information collected from your Data Management Platform.
  • Manage Optimizely projects from an internal system.
  • Pull results data into an internal dashboard or results widget.
  • Send email alerts when specific results are achieved.

Use the REST API

To use the Optimizely REST API, you must authenticate by generating an API token. For information on how to do so, refer to the documentation on how to Manage your API tokens.
