How to Get Data Collected

If your Feature Flag or Experiment is not collecting data, follow this checklist to identify the cause. The checks are divided between the Back Office and the SDK.

In the Back Office​

Make sure the following conditions are met:

  • The rule is created for the correct environment (production, staging, or development).
  • The rule is enabled (turned on).
  • The rule targets traffic that can actually be exposed (i.e. matching segments or visitors).

In the SDK​

Check these points carefully:

  • The KameleoonClient is created with the correct configuration:

    • siteCode
    • environment variable
    • networkDomain (if applicable)

  • getVisitorCode() is called only once, and its value is reused wherever the visitorCode is needed.

  • If using Hybrid Mode (with engine.js on the frontend):

    • The visitorCode is correctly synced between the SDK and the frontend.

  • For Experiment Rules:

    • setLegalConsent(true) is called to ensure that data collection is allowed.

  • For Delivery Rules:

    • isFeatureActive() or getVariation() is called.
    • The method returns true (or the expected variation).

  • For Experiment Rules:

    • getVariation() is called and returns the expected variation.

Debugging Tips​

If you’ve confirmed all of the above and data is still missing:

  • Log in the console:

    • The consent value
    • The visitorCode
    • The variation values Verify that they match what you see in the browser.

  • Enable SDK logging and check for any errors.
