What SDK calls are local and which ones send data to VWO?

Following calls are responsible for tracking data from the server where SDK is implemented to the VWO server:

  • activate API sends a visitor-tracking call to the VWO server so that the same could be reflected in the respective server-side running A/B campaigns' report along with providing the variation assigned for a particular user.

  • isFeatureEnabled API sends a visitor-tracking call to the VWO server so that the same could be reflected in the respective server-side running Feature Test campaigns report along with providing the decision whether the feature is enabled for a particular user.

  • track API sends a conversion-tracking call to the VWO server so that the same could be reflected in the respective server-side running campaigns report. This API is applicable for A/B and Feature Test both.
