How to automate Optimizely

Native integrations

The platform has product integrations across its suite. Connect your analytics first, so every experiment reports on the same goals you already track.

Automation idea: send each experiment's result to your team chat when it reaches significance, with the winning variant named.

API and webhooks

The developer documentation lists REST APIs for several products, including campaign and content APIs, and SDKs for feature experimentation. Use the SDKs to run tests in your own code.

Automation idea: wire a feature flag to a gradual rollout, so a new checkout step goes to a small share of visitors first.

MCP server

The vendor publishes MCP servers for parts of its platform, including an Analytics MCP server and a CMS (SaaS) MCP server. Check which products your plan includes before you plan around them.

Automation idea: ask an assistant to summarise last quarter's experiments and list which hypotheses were confirmed.
