Visual Website Optimizer API was privately announced to select users long time back but today we are happy to announce it to general public too. The API lets you pull complete test results into your internal dashboards. Results are returned for all test goals and include confidence levels, hits and conversions. amongst other metrics. The API also allows you to start and pause tests programmatically.
API interface is JSON and is currently available only by request. If you wish to use the API, email us at firstname.lastname@example.org and we will provide you an access token and documentation for using the API.
